2 Feedback and Troubleshooting

If things do not work, especially simple things like ant -version, then something is wrong with your configuration. Before filing bug reports and emailing all the ant mailing lists

1. Check your environment variables. Are ANT_HOME and JAVA_HOME correct? If they have quotes or trailing slashes, remove them.

2. Unset CLASSPATH; if that is wrong things go horribly wrong. Ant does not need the

CLASSPATH variable defined to anything to work.

3. Make sure there are no versions of crimson.jar or other XML parsers in JRE/ext

4. Is your path correct? is Ant on it? What about JDK/bin? have you tested this? If you are using Jikes, is it on the path? A createProcess error (especially with ID=2 on windows) usually means executable not found on the path.

5. Which version of ant are you running? Other applications distribute a copy -it may be being picked up by accident.

6. If a task is failing to run is optional.jar in ANT_HOME/lib? Are there any libraries which it depends on missing?

7. If a task doesn't do what you expect, run ant -verbose or ant -debug to see what is happening

If you can't fix your problem, start with the Ant User Mailing List . These are other ant users who will help you learn to use ant. If they cannot fix it then someone may suggest filing a bug report, which will escalate the issue. Remember of course, that support, like all open source development tasks, is voluntary. If you haven't invested time in helping yourself by following the steps above, it is unlikely that anyone will invest the time in helping you.

Also, if you don't understand something, the Ant User Mailing List is the place to ask questions. Not the developer list, nor the individuals whose names appears in the source and documentation. If they answered all such emails, nobody would have any time to improve ant.

To provide feedback on this software, please subscribe to the Ant User Mailing List

If you want to contribute to Ant or stay current with the latest development, join the Ant

Development Mailing List

Archives of both lists can be found at http://archives.apache.org/eyebrowse/ViewLists . A searchable archive can be found at http://marc.theaimsgroup.com

. If you know of any additional archive sites, please report them to the lists.

Ant Manual 1.5.4 12/9/2003 7:47 PM

3 Introduction

This is the manual for version 1.5.4 of Apache Ant . If your version of Ant (as verified with ant -version) is older or newer than this version then this is not the correct manual set.

Please use the documentation appropriate to your current version. Also, if you are using a version older than the most recent release, we recommend an upgrade to fix bugs as well as provide new functionality.

Apache Ant is a Java-based build tool. In theory, it is kind of like make, without make's wrinkles.

3.1 Why?

Why another build tool when there is already make, gnumake, nmake, jam, and others?

Because all those tools have limitations that Ant's original author couldn't live with when developing software across multiple platforms. Make-like tools are inherently shell-based: they evaluate a set of dependencies, then execute commands not unlike what you would issue on a shell. This means that you can easily extend these tools by using or writing any program for the OS that you are working on; however, this also means that you limit yourself to the OS, or at least the OS type, such as Unix, that you are working on.

Makefiles are inherently evil as well. Anybody who has worked on them for any time has run into the dreaded tab problem. "Is my command not executing because I have a space in front of my tab?!!" said the original author of Ant way too many times. Tools like Jam took care of this to a great degree, but still have yet another format to use and remember.

Ant is different. Instead of a model where it is extended with shell-based commands, Ant is extended using Java classes. Instead of writing shell commands, the configuration files are

XML-based, calling out a target tree where various tasks get executed. Each task is run by an object that implements a particular Task interface.

Granted, this removes some of the expressive power that is inherent in being able to construct a shell command such as `find . -name foo -exec rm {}`, but it gives you the ability to be cross-platform - to work anywhere and everywhere. And hey, if you really need to execute a shell command, Ant has an <exec > task that allows different commands to be executed based on the OS it is executing on.

4 Installing Ant

4.1 Getting Ant

4.1.1 Binary Edition

The latest stable version of Ant is available from the Ant web page http://ant.apache.org/ .

If you like living on the edge, you can download the latest version from http://cvs.apache.org/builds/ant/nightly/ .

4.1.2 Source Edition

If you prefer the source edition, you can download the source for the latest Ant release from http://ant.apache.org/srcdownload.cgi

. Again, if you prefer the edge, you can access the code as it is being developed via CVS. The Jakarta website has details on accessing CVS .

Please checkout the ant module. See the section Building Ant on how to build Ant from the source code. You can also access the Ant CVS repository on-line.

4.2 System Requirements

Ant has been used successfully on many platforms, including Linux, commercial flavours of

Unix such as Solaris and HP-UX, Windows 9x and NT, Novell Netware 6 and MacOS X.

To build and use Ant, you must have a JAXP-compliant XML parser installed and available on your classpath.

The binary distribution of Ant includes the latest version of the Apache Xerces2 XML parser.

Please see http://java.sun.com/xml/ for more information about JAXP. If you wish to use a different JAXP-compliant parser, you should remove xercesImpl.jar and xml-apis.jar from Ant's lib directory. You can then either put the jars from your preferred parser into

Ant's lib directory or put the jars on the system classpath.

For the current version of Ant, you will also need a JDK installed on your system, version

1.1 or later. Some tasks work better on post-1.1 systems; some tasks only work on Java

1.2 and successors. A future version of Ant -Ant 2.0- will require JDK 1.2 or later, though

Ant 1.x strives to retain 1.1 compatibility.

Note: The Microsoft JVM/JDK is not adequate on its own, although the MS compiler is supported.

Note #2: If a JDK is not present, only the JRE runtime, then many tasks will not work.

4.3 Installing Ant

The binary distribution of Ant consists of the following directory layout:

ant

+--- bin // contains launcher scripts

|

+--- lib // contains Ant jars plus necessary dependencies

|

+--- docs // contains documentation

| +--- ant2 // a brief description of ant2 requirements

| |

| +--- images // various logos for html documentation

| |

| +--- manual // Ant documentation (a must read ;-)

|

14/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

+--- etc // contains xsl goodies to:

// - create an enhanced report from xml output of various tasks.

// - migrate your build files and get rid of 'deprecated' warning

// - ... and more ;-)

Only the bin and lib directories are required to run Ant. To install Ant, choose a directory and copy the distribution file there. This directory will be known as ANT_HOME.

Windows 95, Windows 98 & Windows ME Note:

On these systems, the script used to launch Ant will have problems if ANT_HOME is a long filename (i.e. a filename which is not of the format known as "8.3"). This is due to limitations in the OS's handling of the "for" batch-file statement. It is recommended, therefore, that Ant be installed in a short, 8.3 path, such as C:\Ant

.

• On these systems you will also need to configure more environment space to cater for the environment variables used in the Ant lauch script. To do this, you will need to add or update the following line in the config.sys file shell=c:\command.com c:\ /p /e:32768

4.3.1 Setup

Before you can run ant there is some additional set up you will need to do:

• Add the bin directory to your path.

• Set the ANT_HOME environment variable to the directory where you installed Ant. On some operating systems the ant wrapper scripts can guess ANT_HOME (Unix dialects and Windows NT/2000) - but it is better to not rely on this behavior.

• Optionally, set the JAVA_HOME environment variable (see the Advanced section below). This should be set to the directory where your JDK is installed.

Note: Do not install Ant's ant.jar file into the lib/ext directory of the JDK/JRE. Ant is an application, whilst the extension directory is intended for JDK extensions. In particular there are security restrictions on the classes which may be loaded by an extension.

4.3.2 Optional Tasks

Ant supports a number of optional tasks. An optional task is a task which typically requires an external library to function. The optional tasks are packaged together with the core Ant tasks.

The external libraries required by each of the optional tasks is detailed in the Library

Dependencies section. These external libraries may either be placed in Ant's lib directory, where they will be picked up automatically, or made available on the system CLASSPATH environment variable.

4.3.3 Windows

Assume Ant is installed in c:\ant\. The following sets up the environment: set ANT_HOME=c:\ant set JAVA_HOME=c:\jdk1.2.2 set PATH=%PATH%;%ANT_HOME%\bin

15/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

4.3.4 Unix (bash)

Assume Ant is installed in /usr/local/ant. The following sets up the environment: export ANT_HOME=/usr/local/ant export JAVA_HOME=/usr/local/jdk-1.2.2 export PATH=${PATH}:${ANT_HOME}/bin

4.3.5 Unix (csh)

setenv ANT_HOME /usr/local/ant setenv JAVA_HOME /usr/local/jdk-1.2.2 set path=( $path $ANT_HOME/bin )

4.3.6 Advanced

There are lots of variants that can be used to run Ant. What you need is at least the following:

• The classpath for Ant must contain ant.jar and any jars/classes needed for your chosen

JAXP-compliant XML parser.

• When you need JDK functionality (such as for the javac task or the rmic task), then for

JDK 1.1, the classes.zip file of the JDK must be added to the classpath; for JDK 1.2 or

JDK 1.3, tools.jar must be added. The scripts supplied with Ant, in the bin directory, will add the required JDK classes automatically, if the JAVA_HOME environment variable is set.

• When you are executing platform-specific applications, such as the exec task or the cvs task, the property ant.home must be set to the directory containing where you installed

Ant. Again this is set by the Ant scripts to the value of the ANT_HOME environment variable.

The supplied ant shell scripts all support an ANT_OPTS environment variable which can be used to supply extra options to ant. Some of the scripts also read in an extra script stored in the users home directory, which can be used to set such options. Look at the source for your platform's invocation script for details.

4.4 Building Ant

To build Ant from source, you can either install the Ant source distribution or checkout the ant module from CVS.

Once you have installed the source, change into the installation directory.

Set the JAVA_HOME environment variable to the directory where the JDK is installed. See

Installing Ant for examples on how to do this for your operating system.

Make sure you have downloaded any auxiliary jars required to build tasks you are interested in. These should either be available on the CLASSPATH or added to the lib directory. See

Library Dependencies for a list of jar requirements for various features. Note that this will make the auxiliary jars available for the building of Ant only. For running Ant you will still need to make the jars available as described under Installing Ant .

Your are now ready to build Ant: build -Ddist.dir=<directory_to_contain_Ant_distribution> dist

(Windows)

16/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

build.sh -Ddist.dir=<directory_to_contain_Ant_distribution> dist

(Unix)

This will create a binary distribution of Ant in the directory you specified.

The above action does the following:

• If necessary it will bootstrap the Ant code. Bootstrapping involves the manual compilation of enough Ant code to be able to run Ant. The bootstrapped Ant is used for the remainder of the build steps.

• Invokes the bootstrapped Ant with the parameters passed to the build script. In this case, these parameters define an Ant property value and specify the "dist" target in

Ant's own build.xml file.

On most occasions you will not need to explicitly bootstrap Ant since the build scripts do that for you. If however, the build file you are using makes use of features not yet compiled into the bootstrapped Ant, you will need to manually bootstrap. Run bootstrap.bat

(Windows) or bootstrap.sh (UNIX) to build a new bootstrap version of Ant.

If you wish to install the build into the current ANT_HOME directory, you can use: build install

(Windows) build.sh install

(Unix)

You can avoid the lengthy Javadoc step, if desired, with: build install-lite

(Windows) build.sh install-lite

(Unix)

This will only install the bin and lib directories.

Both the install and install-lite targets will overwrite the current Ant version in

ANT_HOME

.

4.5 Library Dependencies

The following libraries are needed in your CLASSPATH or in the install directory's lib directory if you are using the indicated feature. Note that only one of the regexp libraries is needed for use with the mappers. You will also need to install the Ant optional jar containing the task definitions to make these tasks available. Please refer to the Installing Ant /

Optional Tasks section above.

4.6 Platform Issues

4.6.1 Unix

You should use a GNU version of tar to untar the ant source tree, if you have downloaded this as a tar file.

Ant does not preserve file permissions when a file is copied, moved or archived. Use

<chmod> to set permissions, and when creating a tar archive, use the mode attribute of

<tarfileset> to set the permissions in the tar file.

• Ant is not symbolic link aware in moves, deletes and when recursing down a tree of directories to build up a list of files. Unexpected things can happen.

18/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

4.6.2 Microsoft Windows

Windows 9x (win95, win98, win98SE and winME) has a batch file system which does not work fully with long file names, so we recommend that ant and the JDK are installed into directories without spaces, and with 8.3 filenames. The Perl and Python launcher scripts do not suffer from this limitation.

All versions of windows are usually case insensitive, although mounted file systems (Unix drives, Clearcase views) can be case sensitive underneath, confusing patternsets.

Ant can often not delete a directory which is open in an Explorer window. There is nothing we can do about this short of spawning a program to kill the shell before deleting directories.

4.6.3 Apple MacOS X

MacOS X is the first of the Apple platforms that Ant supports completely; it is treated like any other Unix.

4.6.4 Novell Netware

To give the same level of sophisticated control as Ant's startup scripts on other platforms, it was decided to make the main ant startup on NetWare be via a Perl Script, "runant.pl". This is found in the bin directory (for instance - bootstrap\bin or dist\bin).

One important item of note is that you need to set up the following to run ant:

CLASSPATH

- put ant.jar, xercesImpl.jar, xml-apis.jar and any other needed jars on the system classpath.

ANT_OPTS

- On NetWare, ANT_OPTS needs to include a parameter of the form, "envCWD=ANT_HOME", with ANT_HOME being the fully expanded location of Ant, not an environment variable. This is due to the fact that the NetWare System Console has no notion of a current working directory.

It is suggested that you create up an ant.ncf that sets up these parameters, and calls perl

ANT_HOME/dist/bin/runant.pl

The following is an example of such an NCF file(assuming ant is installed in 'sys:/apacheant/'):

envset CLASSPATH=SYS:/apache-ant/bootstrap/lib/ant.jar

envset CLASSPATH=$CLASSPATH;SYS:/apache-ant/lib/xercesImpl.jar

envset CLASSPATH=$CLASSPATH;SYS:/apache-ant/lib/xml-apis.jar

envset CLASSPATH=$CLASSPATH;SYS:/apache-ant/lib/optional/junit.jar

envset CLASSPATH=$CLASSPATH;SYS:/apache-ant/bootstrap/lib/optional.jar

setenv ANT_OPTS=-envCWD=sys:/apache-ant

envset ANT_OPTS=-envCWD=sys:/apache-ant

setenv ANT_HOME=sys:/apache-ant/dist/lib

envset ANT_HOME=sys:/apache-ant/dist/lib

perl sys:/apache-ant/dist/bin/runant.pl

19/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Ant works on JVM version 1.3 or higher. You may have some luck running it on JVM 1.2, but serious problems have been found running Ant on JVM 1.1.7B. These problems are caused by JVM bugs that will not be fixed.

JVM 1.3 is supported on Novell NetWare versions 5.1 and higher.

4.6.5 Other platforms

Support for other platforms is not guaranteed to be complete, as certain techniques to hide platform details from build files need to be written and tested on every particular platform.

Contributions in this area are welcome.

5 Running Ant

5.1 Command Line

If you've installed Ant as described in the Installing Ant section, running Ant from the command-line is simple: just type ant.

When no arguments are specified, Ant looks for a build.xml file in the current directory and, if found, uses that file as the build file and runs the target specified in the default attribute of the <project> tag. To make Ant use a build file other than build.xml, use the command-line option -buildfile file, where file is the name of the build file you want to use.

If you use the -find [file] option, Ant will search for a build file first in the current directory, then in the parent directory, and so on, until either a build file is found or the root of the filesystem has been reached. By default, it will look for a build file called build.xml.

To have it search for a build file other than build.xml, specify a file argument. Note: If you include any other flags or arguments on the command line after the -find flag, you must include the file argument for the -find flag, even if the name of the build file you want to find is build.xml.

You can also set properties on the command line. This can be done with the -

Dproperty=value

option, where property is the name of the property, and value is the value for that property. If you specify a property that is also set in the build file (see the property task), the value specified on the command line will override the value specified in the build file. Defining properties on the command line can also be used to pass in the value of environment variables - just pass -DMYVAR=%MYVAR% (Windows) or -DMYVAR=$MYVAR

(Unix) to Ant. You can then access these variables inside your build file as ${MYVAR}. You can also access environment variables using the property task's environment attribute.

Options that affect the amount of logging output by Ant are: -quiet, which instructs Ant to print less information to the console; -verbose, which causes Ant to print additional information to the console; and -debug, which causes Ant to print considerably more additional information.

It is also possible to specify one or more targets that should be executed. When omitted, the target that is specified in the default attribute of the project

tag is used.

The -projecthelp option prints out a list of the build file's targets. Targets that include a description

attribute are listed as "Main targets", those without a description are listed as "Subtargets", then the "Default" target is listed.

Command-line Options Summary

ant [options] [target [target2 [target3] ...]]

Options:

-help print this message

-projecthelp print project help information

-version print the version information and exit

-diagnostics print information that might be helpful to

diagnose or report problems.

-quiet, -q be extra quiet

21/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

-verbose, -v be extra verbose

-debug print debugging information

-emacs produce logging information without adornments

-logfile <file> use given file for log

-l <file> ''

-logger <classname> the class which is to perform logging

-listener <classname> add an instance of class as a project listener

-buildfile <file> use given buildfile

-file <file> ''

-f <file> ''

-D<property>=<value> use value for given property

-propertyfile <name> load all properties from file with -D

properties taking precedence

-inputhandler <class> the class which will handle input requests

-find <file> search for buildfile towards the root of the

filesystem and use it

For more information about -logger and -listener see Loggers & Listeners .

For more information about -inputhandler see InputHandler .

Examples

ant runs Ant using the build.xml file in the current directory, on the default target. ant -buildfile test.xml runs Ant using the test.xml file in the current directory, on the default target. ant -buildfile test.xml dist runs Ant using the test.xml file in the current directory, on the target called dist. ant -buildfile test.xml -Dbuild=build/classes dist runs Ant using the test.xml file in the current directory, on the target called dist, setting the build property to the value build/classes.

Files

The Ant wrapper script for Unix will source (read and evaluate) the file ~/.antrc before it does anything. On Windows, the Ant wrapper batch-file invokes %HOME%\antrc_pre.bat at the start and %HOME%\antrc_post.bat at the end. You can use these files, for example, to set/unset environment variables that should only be visible during the execution of Ant. See the next section for examples.

Environment Variables

The wrapper scripts use the following env ironment variables (if set):

JAVACMD

- full path of the Java executable. Use this to invoke a different JVM than

JAVA_HOME/bin/java(.exe)

.

22/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

ANT_OPTS

- command-line arguments that should be passed to the JVM. For example, you can define system properties or set the maximum Java heap size here.

ANT_ARGS

- Ant command-line arguments. For example, set ANT_ARGS to point to a different logger, include a listener, and to include the -find flag. Note: If you include -find in ANT_ARGS, you should include the name of the build file to find, even if the file is called build.xml.

5.2 Cygwin Users

The Unix launch script that come with Ant works correctly with Cygwin. You should not have any problems launching Ant form the Cygwin shell. It is important to note however, that once Ant is runing it is part of the JDK which operates as a native Windows application. The

JDK is not a Cygwin executable, and it therefore has no knowledge of the Cygwin paths, etc.

In particular when using the <exec> task, executable names such as "/bin/sh" will not work, even though these work from the Cygwin shell from which Ant was launched. You can use an executable name such as "sh" and rely on that command being available in the

Windows path.

5.3 Running Ant via Java

If you have installed Ant in the do-it-yourself way, Ant can be started with: java -Dant.home=c:\ant org.apache.tools.ant.Main [options] [target]

These instructions actually do exactly the same as the ant command. The options and target are the same as when running Ant with the ant command. This example assumes you have set your classpath to include:

• ant.jar

• jars/classes for your XML parser

• the JDK's required jar/zip files

23/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

6 Using Ant

6.1 Writing a Simple Buildfile

Ant's buildfiles are written in XML. Each buildfile contains one project and at least one

(default) target. Targets contain task elements. Each task element of the buildfile can have an id attribute and can later be referred to by the value supplied to this. The value has to be unique. (For additional information, see the Tasks section below.)

6.1.1 Projects

A project has three attributes:

Attribute Description Required name the name of the project. default the default target to use when no target is supplied.

No

Yes. basedir the base directory from which all path calculations are done. This attribute might be overridden by setting the "basedir" property beforehand. When this is done, it must be omitted in the project tag. If neither the attribute nor the property have been set, the parent directory of the buildfile will be used.

No

Optionally, a description for the project can be provided as a top-level <description> element (see the description type).

Each project defines one or more targets. A target is a set of tasks you want to be executed. When starting Ant, you can select which target(s) you want to have executed.

When no target is given, the project's default is used.

6.1.2 Targets

A target can depend on other targets. You might have a target for compiling, for example, and a target for creating a distributable. You can only build a distributable when you have compiled first, so the distribute target depends on the compile target. Ant resolves these dependencies.

It should be noted, however, that Ant's depends attribute only specifies the order in which targets should be executed - it does not affect whether the target that specifies the dependency(s) gets executed if the dependent target(s) did not (need to) run.

Ant tries to execute the targets in the depends attribute in the order they appear (from left to right). Keep in mind that it is possible that a target can get executed earlier when an earlier target depends on it:

<target name="A"/>

<target name="B" depends="A"/>

<target name="C" depends="B"/>

<target name="D" depends="C,B,A"/>

Suppose we want to execute target D. From its depends attribute, you might think that first target C, then B and then A is executed. Wrong! C depends on B, and B depends on A, so first A is executed, then B, then C, and finally D.

A target gets executed only once, even when more than one target depends on it (see the previous example).

24/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

A target also has the ability to perform its execution if (or unless) a property has been set.

This allows, for example, better control on the building process depending on the state of the system (java version, OS, command-line property defines, etc.). To make a target

sense this property, you should add the if (or unless) attribute with the name of the property that the target should react to. Note: Ant will only check whether the property has been set, the value doesn't matter. A property set to the empty string is still an existing property. For example:

<target name="build-module-A" if="module-A-present"/>

<target name="build-own-fake-module-A" unless="module-A-present"/>

In the first example, if the module-A-present property is set (to any value), the target will be run. In the second example, if the module-A-present property is set (again, to any value), the target will not be run.

If no if and no unless attribute is present, the target will always be executed.

The optional description attribute can be used to provide a one-line description of this target, whic h is printed by the -projecthelp command-line option. Targets without such a description are deemed internal and will not be listed, unless either the -verbose or -debug option is used.

It is a good practice to place your tstamp tasks in a so-called initialization target, on which all other targets depend. Make sure that target is always the first one in the depends list of the other targets. In this manual, most initialization targets have the name "init".

A target has the following attributes:

Attribute Description name the name of the target. depends a comma-separated list of names of targets on which this target depends. if the name of the property that must be set in order for this target to execute. unless the name of the property that must not be set in order for this target to execute. description a short description of this target's function.

Required

Yes

No

No

No

No

A target name can be any alphanumeric string valid in the encoding of the XML file. The empty string "" is in this set, as is comma "," and space " ". Please avoid using these, as they will not be supported in future Ant versions because of all the confusion they cause.

IDE support of unusual target names, or any target name containing spaces, varies with the

IDE.

Targets beginning with a hyphen such as "-restart" are valid, and can be used to name targets that should not be called directly from the command line.

6.1.3 Tasks

A task is a piece of code that can be executed.

A task can have multiple attributes (or arguments, if you prefer). The value of an attribute might contain references to a property. These references will be resolved before the task is executed.

25/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Tasks have a common structure:

<name attribute1="value1" attribute2="value2" ... /> where name is the name of the task, attributeN is the attribute name, and valueN is the value for this attribute.

There is a set of built-in tasks , along with a number of optional tasks , but it is also very easy to write your own .

All tasks share a task name attribute. The value of this attribute will be used in the logging messages generated by Ant.

Tasks can be assigned an id attribute:

<taskname id="taskID" ... /> where taskname is the name of the task, and taskID is a unique identifier for this task. You can refer to the corresponding task object in scripts or other tasks via this name. For example, in scripts you could do:

<script ... >

task1.setFoo("bar");

</script> to set the foo attribute of this particular task instance. In another task (written in Java), you can access the instance via project.getReference("task1").

Note

1

: If "task1" has not been run yet, then it has not been configured (ie., no attributes have been set), and if it is going to be configured later, anything you've done to the instance may be overwritten.

Note

2

: Future versions of Ant will most likely not be backward-compatible with this behaviour, since there will likely be no task instances at all, only proxies.

6.1.4 Properties

A project can have a set of properties. These might be set in the buildfile by the property task, or might be set outside Ant. A property has a name and a value; the name is casesensitive. Properties may be used in the value of task attributes. This is done by placing the property name between "${" and "}" in the attribute value. For example, if there is a

"builddir" property with the value "build", then this could be used in an attribute like this:

${builddir}/classes. This is resolved at run-time as build/classes.

6.1.5 Built-in Properties

Ant provides access to all system properties as if they had been defined using a <property> task. For example, ${os.name} expands to the name of the operating system.

For a list of system properties see the Javadoc of System.getProperties

.

In addition, Ant has some built-in properties:

26/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

basedir the absolute path of the project's basedir (as set

with the basedir attribute of <project>). ant.file the absolute path of the buildfile. ant.version the version of Ant ant.project.name the name of the project that is currently executing;

it is set in the name attribute of <project>. ant.java.version the JVM version Ant detected; currently it can hold

the values "1.1", "1.2", "1.3" and "1.4".

6.1.6 Example Buildfile

<project name="MyProject" default="dist" basedir=".">

<description>

simple example build file

</description>

<!-- set global properties for this build -->

<property name="src" location="src"/>

<property name="build" location="build"/>

<property name="dist" location="dist"/>

<target name="init">

<!-- Create the time stamp -->

<tstamp/>

<!-- Create the build directory structure used by compile -->

<mkdir dir="${build}"/>

</target>

<target name="compile" depends="init"

description="compile the source " >

<!-- Compile the java code from ${src} into ${build} -->

<javac srcdir="${src}" destdir="${build}"/>

</target>

<target name="dist" depends="compile"

description="generate the distribution" >

<!-- Create the distribution directory -->

<mkdir dir="${dist}/lib"/>

<!-- Put everything in ${build} into the MyProject-${DSTAMP}.jar file -->

<jar jarfile="${dist}/lib/MyProject-${DSTAMP}.jar" basedir="${build}"/>

</target>

<target name="clean"

description="clean up" >

<!-- Delete the ${build} and ${dist} directory trees -->

<delete dir="${build}"/>

<delete dir="${dist}"/>

</target>

</project>

Notice that we are declaring properties outside any target. The <property>,<typedef> and

<taskdef>

tasks are special in that they can be declared outside any target. When you do this they are evaluated before any targets are executed. No other tasks can be declared outside targets.

27/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

We have given some targets descriptions; this causes the projecthelp invocation option to list them as public targets with the descriptions; the other target is internal and not listed.

Finally, for this target to work the source in the src subdirectory should be stored in a directory tree which matches the package names. Check the <javac> task for details.

6.1.7 Token Filters

A project can have a set of tokens that might be automatically expanded if found when a file is copied, when the filtering-copy behavior is selected in the tasks that support this. These might be set in the buildfile by the filter task.

Since this can potentially be a very harmful behavior, the tokens in the files must be of the form @token@, where token is the token name that is set in the <filter> task. This token syntax matches the syntax of other build systems that perform such filtering and remains sufficiently orthogonal to most programming and scripting languages, as well as with documentation systems.

Note: If a token with the format @token@ is found in a file, but no filter is associated with that token, no changes take place; therefore, no escaping method is available - but as long as you choose appropriate names for your tokens, this should not cause problems.

Warning: If you copy binary files with filtering turned on, you can corrupt the files. This feature should be used with text files only.

6.1.8 Path-like Structures

You can specify PATH- and CLASSPATH-type references using both ":" and ";" as separator characters. Ant will convert the separator to the correct character of the current operating system.

Wherever path-like values need to be specified, a nested element can be used. This takes the general form of:

<classpath>

<pathelement path="${classpath}"/>

<pathelement location="lib/helper.jar"/>

</classpath>

The location attribute specifies a single file or directory relative to the project's base directory (or an absolute filename), while the path attribute accepts colon- or semicolonseparated lists of locations. The path attribute is intended to be used with predefined paths

- in any other case, multiple elements with location attributes should be preferred.

As a shortcut, the <classpath> tag supports path and location attributes of its own, so:

<classpath>

<pathelement path="${classpath}"/>

</classpath> can be abbreviated to:

<classpath path="${classpath}"/>

28/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

In addition, DirSet s, FileSet s, and FileList s can be specified via nested <dirset>,

<fileset>

, and <filelist> elements, respectively. Note: The order in which the files building up a FileSet are added to the path-like structure is not defined.

<classpath>

<pathelement path="${classpath}"/>

<fileset dir="lib">

<include name="**/*.jar"/>

</fileset>

<pathelement location="classes"/>

<dirset dir="${build.dir}">

<include name="apps/**/classes"/>

<exclude name="apps/**/*Test*"/>

</dirset>

<filelist refid="third-party_jars">

</classpath>

This builds a path that holds the value of ${classpath}, followed by all jar files in the lib directory, the classes directory, all directories named classes under the apps subdirectory of ${build.dir}, except those that have the text Test in their name, and the files specified in the referenced FileList.

If you want to use the same path-like structure for several tasks, you can define them with a <path> element at the same level as targets, and reference them via their id attribute - see References for an example.

A path-like structure can include a reference to another path-like structure via nested

<path>

elements:

<path id="base.path">

<pathelement path="${classpath}"/>

<fileset dir="lib">

<include name="**/*.jar"/>

</fileset>

<pathelement location="classes"/>

</path>

<path id="tests.path">

<path refid="base.path"/>

<pathelement location="testclasses"/>

</path>

The shortcuts previously mentioned for <classpath> are also valid for <path>.For example:

<path id="base.path">

<pathelement path="${classpath}"/>

</path> can be written as:

<path id="base.path" path="${classpath}"/>

29/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

6.1.9 Command-line Arguments

Several tasks take arguments that will be passed to another process on the command line.

To make it easier to specify arguments that contain space characters, nested arg elements can be used.

Attribute Description Required value file path line a single command-line argument; can contain space characters.

The name of a file as a single command-line argument; will be replaced with the absolute filename of the file.

A string that will be treated as a path-like string as a single command-line argument; you can use ; or : as path separators and Ant will convert it to the platform's local conventions.

Exactly one of these. a space-delimited list of command-line arguments.

It is highly recommended to avoid the line version when possible. Ant will try to split the command line in a way similar to what a (Unix) shell would do, but may create something that is very different from what you expect under some circumstances.

6.1.10 Examples

<arg value="-l -a"/> is a single command-line argument containing a space character.

<arg line="-l -a"/> represents two separate command-line arguments.

<arg path="/dir;/dir2:\dir3"/> is a single command-line argument with the value \dir;\dir2;\dir3 on DOS-based systems and /dir:/dir2:/dir3 on Unix-like systems.

6.1.11 References

The id attribute of the buildfile's elements can be used to refer to them. This can be useful if you are going to replicate the same snippet of XML over and over again - using a

<classpath> structure more than once, for example.

The following example:

<project ... >

<target ... >

<rmic ...>

<classpath>

<pathelement location="lib/"/>

<pathelement path="${java.class.path}/"/>

<pathelement path="${additional.path}"/>

</classpath>

</rmic>

</target>

<target ... >

<javac ...>

30/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<classpath>

<pathelement location="lib/"/>

<pathelement path="${java.class.path}/"/>

<pathelement path="${additional.path}"/>

</classpath>

</javac>

</target>

</project> could be rewritten as:

<project ... >

<path id="project.class.path">

<pathelement location="lib/"/>

<pathelement path="${java.class.path}/"/>

<pathelement path="${additional.path}"/>

</path>

<target ... >

<rmic ...>

<classpath refid="project.class.path"/>

</rmic>

</target>

<target ... >

<javac ...>

<classpath refid="project.class.path"/>

</javac>

</target>

</project>

All tasks that use nested elements for PatternSet s, FileSet s or path-like structures accept references to these structures as well.

7 Concepts

7.1 build.sysclasspath

The value of the build.sysclasspath property control how the system classpath, ie. the classpath in effec t when Ant is run, affects the behaviour of classpaths in Ant. The default behavior varies from Ant to Ant task.

The values and their meanings are:

only

Only the system classpath is used and classpaths specified in build files, etc are ignored. This situation could be considered as the person running the build file knows more about the environment than the person writing the build file

ignore The system classpath is ignored. This situation is the reverse of the above. The person running the build trusts the build file writer to get the build file right

last first

The classpath is concatenated to any specified classpaths at the end. This is a compromise, where the build file writer has priority.

Any specified classpaths are concatenated to the system classpath. This is the other form of compromise where the build runner has priority.

7.2 Common Attributes of all Tasks

All tasks share the following attributes:

Attribute Description Required

id Unique identifier for this task instance, can be used to reference this task in scripts.

No taskname A different name for this task instance - will show up in the logging output. description Room for your comments

No

</description>

7.3.2 Directory-based Tasks

Some tasks use directory trees for the actions they perform. For example, the javac task, which compiles a directory tree with .java files into .class files, is one of these directorybased tasks. Because some of these tasks do so much work with a directory tree, the task itself can act as an implicit FileSet .

32/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Whether the fileset is implicit or not, it can often be very useful to work on a subset of the directory tree. This section describes how you can select a subset of such a directory tree when using one of these directory-based tasks.

Ant gives you two ways to create a subset of files in a fileset, both of which can be used at the same time:

• Only include files and directories that match any include patterns and do not match any exclude patterns in a given PatternSet .

• Select files based on selection criteria defined by a collection of selector nested elements.

Patternset

We said that Directory-based tasks can sometimes act as an implicit <fileset> , but in addtion to that, a FileSet acts as an implicit <patternset> .

The inclusion and exclusion elements of the implicit PatternSet can be specified inside the directory-based task (or explicit fileset) via either:

• the attributes includes and excludes.

• nested elements <include> and <exclude>.

• external files specified with the attributes includesfile and excludesfile.

• external files specified with the nested elements <includesfile> and <excludesfile>.

When dealing with an external file, each line of the file is taken as a pattern that is added to the list of include or exclude patterns.

When both inclusion and exclusion are used, only files/directories that match at least one of the include patterns and don't match any of the exclude patterns are used. If no include pattern is given, all files are assumed to match the include pattern (with the possible exception of the default excludes).

Patterns

As described earlier, patterns are used for the inclusion and exclusion of files. These patterns look very much like the patterns used in DOS and UNIX:

'*' matches zero or more characters, '?' matches one character.

Examples:

*.java

matches .java, x.java and FooBar.java, but not FooBar.xml (does not end with

.java

).

?.java

matches x.java, A.java, but not .java or xyz.java (both don't have one character before .java).

Combinations of *'s and ?'s are allowed.

Matching is done per-directory. This means that first the first directory in the pattern is matched against the first directory in the path to match. Then the second directory is matched, and so on. For example, when we have the pattern /?abc/*/*.java and the path

/xabc/foobar/test.java

, the first ?abc is matched with xabc, then * is matched with

33/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

foobar

, and finally *.java is matched with test.java. They all match, so the path matches the pattern.

To make things a bit more flexible, we add one extra feature, which makes it possible to match multiple directory levels. This can be used to match a complete directory tree, or a file anywhere in the directory tree. To do this, ** must be used as the name of a directory.

When ** is used as the name of a directory in the pattern, it matches zero or more directories. For example: /test/** matches all files/directories under /test/, such as

/test/x.java

, or /test/foo/bar/xyz.html, but not /xyz.xml.

There is one "shorthand" - if a pattern ends with / or \, then ** is appended. For example, mypackage/test/

is interpreted as if it were mypackage/test/**.

Example patterns:

**/CVS/* Matches all files in CVS directories that can be located anywhere in the directory tree.

Matches:

CVS/Repository

org/apache/CVS/Entries

org/apache/jakarta/tools/ant/CVS/Entries

But not:

org/apache/CVS/foo/bar/Entries (foo/bar/ part does not match) org/apache/jakarta/** Matches all files in the org/apache/jakarta directory tree.

Matches:

org/apache/jakarta/tools/ant/docs/index.html

org/apache/jakarta/test.xml

But not:

org/apache/xyz.java

(jakarta/ part is missing). org/apache/**/CVS/* Matches all files in CVS directories that are located anywhere in the directory tree under org/apache.

Matches:

org/apache/CVS/Entries

org/apache/jakarta/tools/ant/CVS/Entries

But not:

org/apache/CVS/foo/bar/Entries

(foo/bar/ part does not match)

**/test/** Matches all files that have a test element in their path, including test as a filename.

When these patterns are used in inclusion and exclusion, you have a powerful way to select just the files you want.

Selectors

The <fileset> , whether implicit or explicit in the directory-based task, also acts as an

<and> selector container. This can be used to create arbitrarily complicated selection criteria for the files the task should work with. See the Selector documentation for more information.

Standard Tasks/Filesets

34/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Many of the standard tasks in ant take one or more filesets which follow the rules given here. This list, a subset of those, is a list of standard ant tasks that can act as an implicit fileset:

• <checksum>

• <copydir> (deprecated)

• <delete>

• <dependset>

• <fixcrlf>

• <javac>

<replace>

<rmic>

<style> (aka <xslt>)

<tar>

<zip>

• <ddcreator>

• <ejbjar>

• <ejbc>

• <cab>

• <icontract>

• <native2ascii>

• <netrexxc>

• <renameextensions>

• <depend>

• <ilasm>

• <csc>

• <vbc>

• <translate>

• <vajexport>

• <image>

• <jlink> (deprecated)

• <jspc>

• <wljspc>

Examples

<copy todir="${dist}">

<fileset dir="${src}"

includes="**/images/*"

excludes="**/*.gif"

/>

</copy>

This copies all files in directories called images that are located in the directory tree defined by ${src} to the destination directory defined by ${dist}, but excludes all *.gif files from the copy.

<copy todir="${dist}">

<fileset dir="${src}">

<include name="**/images/*"/>

<exclude name="**/*.gif"/>

</fileset>

</copy>

35/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

The same as the example above, but expressed using nested elements.

<delete dir="${dist}">

<include name="**/images/*"/>

<exclude name="**/*.gif"/>

</delete>

Deleting the original set of files, the delete task can act as an implicit fileset.

Default Excludes

There are a set of definitions that are excluded by default from all directory-based tasks.

They are:

**/*~

**/#*#

**/.#*

**/%*%

**/._*

**/CVS

**/CVS/**

**/.cvsignore

**/SCCS

**/SCCS/**

**/vssver.scc

**/.svn

**/.svn/**

**/.DS_Store

If you do not want these default excludes applied, you may disable them with the defaultexcludes="no"

attribute.

7.3.3 DirSet

DirSets are groups of directories. These directories can be found in a directory tree starting in a base directory and are matched by patterns taken from a number of PatternSets .

DirSets can appear inside tasks that support this feature or at the same level as target (i.e., as children of <project>).

PatternSets can be specified as nested <patternset> elements. In addition, DirSet holds an implicit PatternSet and supports the nested <include>, <includesfile>, <exclude> and

<excludesfile> elements of <patternset> directly, as well as <patternset>'s attributes.

Attribute

dir

Description

The root of the directory tree of this DirSet.

Required

Yes

No includes A comma- or space -separated list of patterns of directories that must be included; all directories are included when omitted. includesfile The name of a file; each line of this file is taken to be an include pattern. excludes A comma- or space -separated list of patterns of directories that must be excluded; no directories are excluded when omitted. excludesfile The name of a file; each line of this file is taken to be an exclude pattern.

No

No

No

36/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

casesensitive Specifies whether case-sensitivty should be applied (true|yes|on or false|no|off). followsymlinks Shall symbolic links be followed? Defaults to true. See fileset's documentation .

Examples

<dirset dir="${build.dir}">

<include name="apps/**/classes"/>

<exclude name="apps/**/*Test*"/>

</dirset>

No; defaults to true.

No

Groups all directories named classes found under the apps subdirectory of ${build.dir}, except those that have the text Test in their name.

<dirset dir="${build.dir}">

<patternset id="non.test.classes">

<include name="apps/**/classes"/>

<exclude name="apps/**/*Test*"/>

</patternset>

</dirset>

Groups the same directories as the above example, but also establishes a PatternSet that can be referenced in other <dirset> elements, rooted at a different directory.

<dirset dir="${debug_build.dir}">

<patternset refid="non.test.classes"/>

</dirset>

Groups all directories in directory ${debug_build.dir}, using the same patterns as the above example.

7.3.4 FileList

FileLists are explicitly named lists of files. Whereas FileSets act as filters, returning only those files that exist in the file system and match specified patterns, FileLists are useful for specifying files that may or may not exist. Multiple files are specified as a list of files, relative to the specified directory, with no support for wildcard expansion (filenames with wildcards will be included in the list unchanged). FileLists can appear inside tasks that support this feature or at the same level as <target> (i.e., as children of <project>).

Attribute Description Required

dir files

The base directory of this FileList. Yes

The list of file names.

Examples

<filelist

Yes

id="docfiles"

dir="${doc.src}"

files="foo.xml,bar.xml"/>

The files ${doc.src}/foo.xml and ${doc.src}/bar.xml. Note that these files may not

(yet) actually exist.

37/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<filelist

id="docfiles"

dir="${doc.src}"

files="foo.xml

bar.xml"/>

Same files as the example above.

<filelist refid="docfiles"/>

Same files as the example above.

7.3.5 FileSet

FileSets are groups of files. These files can be found in a directory tree starting in a base directory and are matched by patterns taken from a number of PatternSets and Selectors .

FileSets can appear inside tasks that support this feature or at the same level as target - i.e., as children of project.

PatternSets can be specified as nested <patternset> elements. In addition, FileSet holds an implicit PatternSet and supports the nested <include>, <includesfile>, <exclude> and

<excludesfile>

elements of PatternSet directly, as well as PatternSet's attributes.

Selectors are available as nested elements.within the FileSet. If any of the selectors within the FileSet do not select the file, the file is not considered part of the FileSet. This makes

FileSets euqivalent to an <and> selector container.

Attribute Description Required

dir file the root of the directory tree of this FileSet. shortcut for specifying a single file fileset defaultexcludes indicates whether default excludes should be used or not (yes | no); default excludes are used when omitted.

Either dir or file must be specified

No includes No includesfile excludes comma- or space-separated list of patterns of files that must be included; all files are included when omitted. the name of a file; each line of this file is taken to be an include pattern. comma- or space-separated list of patterns of files that must be excluded; no files (except default excludes) are excluded when omitted.

No

No excludesfile the name of a file; each line of this file is taken to be an exclude pattern.

No casesensitive Must the file system be treated in a case sensitive way? Defaults to true.

No followsymlinks Shall symbolic links be followed? Defaults to true. See the note below .

No

Note: All files/directories for which the canonical path is different from its path are considered symbolic links. On Unix systems this usually means the file really is a symbolic links but it may lead to false results on other platforms.

Examples

<fileset dir="${server.src}" casesensitive="yes">

<include name="**/*.java"/>

38/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<exclude name="**/*Test*"/>

</fileset>

Groups all files in directory ${server.src} that are Java source files and don't have the text Test in their name.

<fileset dir="${server.src}" casesensitive="yes">

<patternset id="non.test.sources">

<include name="**/*.java"/>

<exclude name="**/*Test*"/>

</patternset>

</fileset>

Groups the same files as the above example, but also establishes a PatternSet that can be referenced in other <fileset> elements, rooted at a different directory.

<fileset dir="${client.src}" >

<patternset refid="non.test.sources"/>

</fileset>

Groups all files in directory ${client.src}, using the same patterns as the above example.

<fileset dir="${server.src}" casesensitive="yes">

<filename name="**/*.java"/>

<filename name="**/*Test*" negate="true"/>

</fileset>

Groups the same files as the top example, but using the <filename> selector.

<fileset dir="${server.src}" casesensitive="yes">

<filename name="**/*.java"/>

<not>

<filename name="**/*Test*"/>

</not>

</fileset>

Groups the same files as the previous example using a combination of the <filename> selector and the <not> selector container.

7.3.6 Mapping File Names

Some tasks take source files and create target files. Depending on the task, it may be quite obvious which name a target file will have (using javac , you know there will be .class files for your .java files) - in other cases you may want to specify the target files, either to help

Ant or to get an extra bit of functionality.

While source files are usually specified as fileset s, you don't specify target files directly - instead, you tell Ant how to find the target file(s) for one source file. An instance of org.apache.tools.ant.util.FileNameMapper

is responsible for this. It constructs target file names based on rules that can be parameterized with from and to attributes - the exact meaning of which is implementation-dependent.

These instances are defined in <mapper> elements with the following attributes:

39/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Attribute Description Required

type specifies one of the built-in implementations. classname specifies the implementation by class name.

Exactly one of both classpath the classpath to use when looking up classname. No classpathref the classpath to use, given as reference to a path defined elsewhere. No from to the from attribute for the given implementation. the to attribute for the given implementation.

Depends on implementation.

Depends on implementation.

Note that Ant will not automatically convert / or \ characters in the to and from attributes to the correct directory separator of your current platform. If you need to specify this separator, use ${file.separator} instead.

Parameters specified as nested elements

The classpath can be specified via a nested <classpath>, as well - that is, a path -like structure.

The built-in mapper types are:

All built-in mappers are case-sensitive.

identity

The target file name is identical to the source file name. Both to and from will be ignored.

Examples:

<mapper type="identity"/>

Source file name Target file name

A.java foo/bar/B.java

C.properties

A.java foo/bar/B.java

C.properties

Classes/dir/dir2/A.properties Classes/dir/dir2/A.properties

flatten

The target file name is identical to the source file name, with all leading directory information stripped off. Both to and from will be ignored.

Examples:

<mapper type="flatten"/>

Source file name Target file name

A.java A.java foo/bar/B.java B.java

C.properties C.properties

Classes/dir/dir2/A.properties A.properties

merge

The target file name will always be the same, as defined by to - from will be ignored.

Examples:

<mapper type="merge" to="archive.tar"/>

40/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Source file name

A.java foo/bar/B.java

Target file name

archive.tar archive.tar

C.properties archive.tar

Classes/dir/dir2/A.properties archive.tar

glob

Both to and from define patterns that may contain at most one *. For each source file that matches the from pattern, a target file name will be constructed from the to pattern by substituting the * in the to pattern with the text that matches the * in the from pattern.

Source file names that don't match the from pattern will be ignored.

Examples:

<mapper type="glob" from="*.java" to="*.java.bak"/>

Source file name Target file name

A.java A.java.bak foo/bar/B.java foo/bar/B.java.bak

C.properties ignored

Classes/dir/dir2/A.properties ignored

<mapper type="glob" from="C*ies" to="Q*y"/>

Source file name

A.java foo/bar/B.java

Target file name

ignored ignored

C.properties Q.property

Classes/dir/dir2/A.properties Qlasses/dir/dir2/A.property

regexp

Both to and from define regular expressions. If the source file name matches the from pattern, the target file name will be constructed from the to pattern, using \0 to \9 as backreferences for the full match (\0) or the matches of the subexpressions in parentheses.

Source files not matching the from pattern will be ignored.

Note that you need to escape a dollar-sign ($) with another dollar-sign in Ant.

The regexp mapper needs a supporting library and an implementation of org.apache.tools.ant.util.regexp.RegexpMatcher

that hides the specifics of the library.

Ant comes with implementations for the java.util.regex package of JDK 1.4

, jakarta-regexp and jakarta-ORO . If you compile from sources and plan to use one of them, make sure the libraries are in your CLASSPATH. For information about using gnu.regexp

or gnu.rex

with

Ant, see this article.

This means, you need optional.jar from the Ant release you are using and one of the supported regular expression libraries. Make sure, both will be loaded from the same classpath, that is either put them into your CLASSPATH, ANT_HOME/lib directory or a nested

<classpath>

element of the mapper - you cannot have optional.jar in ANT_HOME/lib and the library in a nested <classpath>.

Ant will choose the regular-expression library based on the following algorithm:

41/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

• If the system property ant.regexp.matcherimpl has been set, it is taken as the name of the class implementing org.apache.tools.ant.util.regexp.RegexpMatcher

that should be used.

• If it has not been set, first try the JDK 1.4 classes, then jakarta-ORO and finally try jakarta-regexp.

Examples:

<mapper type="regexp" from="^(.*)\.java$$" to="\1.java.bak"/>

Source file name

A.java

Target file name

A.java.bak foo/bar/B.java

C.properties foo/bar/B.java.bak ignored

Classes/dir/dir2/A.properties ignored

<mapper type="regexp" from="^(.*)/([^/]+)/([^/]*)$$" to="\1/\2/\2-\3"/>

Source file name

A.java foo/bar/B.java

C.properties

Target file name

ignored foo/bar/bar-B.java ignored

Classes/dir/dir2/A.properties Classes/dir/dir2/dir2-A.properties

<mapper type="regexp" from="^(.*)\.(.*)$$" to="\2.\1"/>

Source file name

A.java foo/bar/B.java

C.properties

Target file name

java.A java.foo/bar/B properties.C

Classes/dir/dir2/A.properties properties.Classes/dir/dir2/A

package

Sharing the same syntax as the glob mapper , the package mapper replaces directory separators found in the matched source pattern with dots in the target pattern placeholder.

This mapper is particularly useful in combination with <uptodate> and <junit> output.

Example:

<mapper type="package"

from="*Test.java" to="TEST-*Test.xml"/>

Source file name Target file name

org/apache/tools/ant/util/PackageMapperTest.ja va

TEST-org.apache.tools.ant. util.PackageMapperTest.xml

org/apache/tools/ant/util/Helper.java

ignored

7.3.7 FilterChains and FilterReaders

Look at Unix pipes - they offer you so much flexibility - say you wanted to copy just those lines that contained the st ring blee from the first 10 lines of a file 'foo' to a file 'bar' - you would do something like cat foo|head -n10|grep blee > bar

42/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Ant was not flexible enough. There was no way for the <copy> task to do something similar. If you wanted the <copy> task to get the first 10 lines, you would have had to create special attributes:

<copy file="foo" tofile="bar" head="10" contains="blee"/>

The obvious problem thus surfaced: Ant tasks would not be able to accomodate such data transformation attributes as they would be endless. The task would also not know in which order these attributes were to be interpreted. That is, must the task execute the contains attribute first and then the head attribute or vice-versa? What Ant tasks needed was a mechanism to allow pluggable filter (data tranformer) chains. Ant would provide a few filters for which there have been repeated requests. Users with special filtering needs would be able to easily write their own and plug them in.

The solution was to refactor data transformation oriented tasks to support FilterChains. A

FilterChain is a group of ordered FilterReaders. Users can define their own FilterReaders by just extending the java.io.FilterReader class. Such custom FilterReaders can be easily plugged in as nested elements of <filterchain> by using <filterreader> elements.

Example:

<copy file="${src.file}" tofile="${dest.file}">

<filterchain>

<filterreader classname="your.extension.of.java.io.FilterReader">

<param name="foo" value="bar"/>

</filterreader>

<filterreader classname="another.extension.of.java.io.FilterReader">

<classpath>

<pathelement path="${classpath}"/>

</classpath>

<param name="blah" value="blee"/>

<param type="abra" value="cadabra"/>

</filterreader>

</filterchain>

</copy>

Ant provides some built-in filter readers. These filter readers can also be declared using a syntax similar to the above syntax. However, they can be declared using some simpler syntax also.

Example:

<loadfile srcfile="${src.file}" property="${src.file.head}">

<filterchain>

<headfilter lines="15"/>

</filterchain>

</loadfile> is equivalent to:

<loadfile srcfile="${src.file}" property="${src.file.head}">

<filterchain>

<filterreader classname="org.apache.tools.ant.filters.HeadFilter">

43/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<param name="lines" value="15"/>

</filterreader>

</filterchain>

</loadfile>

The following built-in tasks support nested <filterchain> elements.

Copy ,

LoadFile ,

LoadProperties ,

Move

A FilterChain is formed by defining zero or more of the following nested elements.

ClassConstants

ExpandProperties

HeadFilter

LineContains

LineContainsRegExp

PrefixLines

ReplaceTokens

StripJavaComments

StripLineBreaks

StripLineComments

TabsToSpaces

TailFilter

7.3.8 FilterReader

The filterreader element is the generic way to define a filter. User defined filter elements are defined in the build file using this. Please note that built in filter readers can also be defined using this syntax. A FilterReader element must be supplied with a class name as an attribute value. The class resolved by this name must extend java.io.FilterReader. If the custom filter reader needs to be parameterized, it must implement org.apache.tools.type.Parameterizable.

Attribute Description Required

classname The class name of the filter reader. Yes

Nested Elements:

<filterreader> supports <classpath> and <param> as nested elements. Each <param> element may take in the following attributes - name, type and value.

The following FilterReaders are supplied with the default distribution.

ClassConstants

This filters basic constants defined in a Java Class, and outputs them in lines composed of the format name=value

Example:

44/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

This loads the basic constants defined in a Java class as Ant properties.

<loadproperties srcfile="foo.class">

<filterchain>

<filterreader classname="org.apache.tools.ant.filters.ClassConstants"/>

</filterchain>

</loadproperties>

Convenience method:

<loadproperties srcfile="foo.class">

<filterchain>

<classconstants/>

</filterchain>

</loadproperties>

7.3.9 ExpandProperties

If the data contains data that represents Ant properties (of the form ${...}), that is substituted with the property's actual value.

Example:

This results in the property modifiedmessage holding the value "All these moments will be lost in time, like teardrops in the rain"

<echo

message="All these moments will be lost in time, like teardrops in the

${weather}"

file="loadfile1.tmp"

/>

<property name="weather" value="rain" />

<loadfile property="modifiedmessage" srcFile="loadfile1.tmp">

<filterchain>

<filterreader classname="org.apache.tools.ant.filters.ExpandProperties"/>

</filterchain>

</loadfile>

Convenience method:

<echo

message="All these moments will be lost in time, like teardrops in the

${weather}"

file="loadfile1.tmp"

/>

7.3.20 FilterSet

FilterSets are groups of filters. Filters can be defined as token-value pairs or be read in from a file. FilterSets can appear inside tasks that support this feature or at the same level as

<target> - i.e., as children of <project>.

FilterSets support the id and refid attributes. You can define a FilterSet with an id attribute and then refer to that definition from another FilterSet with a refid attribute. It is also possible to nest filtersets into filtersets to get a set union of the contained filters.

In addition, FilterSets can specify begintoken and/or endtoken attributes to define what to match.

Filtersets are used for doing replacements in tasks such as <copy>, etc.

Filterset

Attribute Description Default Required

begintoken The string marking the beginning of a token (eg., @[email protected]). @ endtoken The string marking the end of a token (eg., @[email protected]).

Filter

Attribute Description

@

Required

No

No token value

The token to replace (eg., @[email protected]) Yes

The value to replace it with (eg., Thursday, April 26, 2001). Yes

Filtersfile

Attribute Description Required

file A properties file of name -value pairs from which to load the tokens. Yes

Examples

You are copying the version.txt file to the dist directory from the build directory but wish to replace the token @[email protected] with today's date.

<copy file="${build.dir}/version.txt" toFile="${dist.dir}/version.txt">

<filterset>

<filter token="DATE" value="${TODAY}"/>

</filterset>

</copy>

You are copying the version.txt file to the dist directory from the build directory but wish to replace the token %DATE* with today's date.

51/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<copy file="${build.dir}/version.txt" toFile="${dist.dir}/version.txt">

<filterset begintoken="%" endtoken="*">

<filter token="DATE" value="${TODAY}"/>

</filterset>

</copy>

Copy all the docs but change all dates and appropriate notices as stored in a file.

<copy toDir="${dist.dir}/docs">

<fileset dir="${build.dir}/docs">

<include name="**/*.html">

</fileset>

<filterset begintoken="%" endtoken="*">

<filtersfile file="${user.dir}/dist.properties"/>

</filterset>

</copy>

Define a FilterSet and reference it later.

<filterset id="myFilterSet" begintoken="%" endtoken="*">

<filter token="DATE" value="${TODAY}"/>

</filterset>

<copy file="${build.dir}/version.txt" toFile="${dist.dir}/version.txt">

<filterset refid="myFilterSet"/>

</copy>

7.3.21 PatternSet

Patterns can be grouped to sets and later be referenced by their id attribute. They are defined via a patternset element, which can appear nested into a FileSet or a directorybased task that constitutes an implicit FileSet. In addition, patternsets can be defined as a stand alone element at the same level as target — i.e., as children of project as well as as children of target.

Patterns can be specified by nested <include>, or <exclude> elements or the following attributes.

Attribute Description

includes comma- or space-separated list of patterns of files that must be included. All files are included when omitted. includesfile the name of a file; each line of this file is taken to be an include pattern. You can specify more than one include file by using a nested includesfile elements. excludes comma- or space-separated list of patterns of files that must be excluded; no files (except default excludes) are excluded when omitted. excludesfile the name of a file; each line of this file is taken to be an exclude pattern. You can specify more than one exclude file by using a nested excludesfile elements.

Parameters specified as nested elements

include

and exclude

Each such element defines a single pattern for files to include or exclude.

Attribute Description Required

52/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

name the pattern to in/exclude. Yes if unless

Only use this pattern if the named property is set. No

Only use this pattern if the named property is not set. No includesfile

and excludesfile

If you want to list the files to include or exclude external to your build file, you should use the includesfile/excludesfile attributes or elements. Using the attribute, you can only specify a single file of each type, while the nested elements can be specified more than once - the nested elements also support if/unless attributes you can use to test the existence of a property.

Attribute Description

name

Required

the name of the file holding the patterns to in/exclude. Yes if unless

Only read this file if the named property is set.

Only read this file if the named property is not set.

No

No patternset

Patternsets may be nested within one another, adding the nested patterns to the parent patternset.

Examples

<patternset id="non.test.sources">

<include name="**/*.java"/>

<exclude name="**/*Test*"/>

</patternset>

Builds a set of patterns that matches all .java files that do not contain the text Test in their name. This set can be referred to via <patternset refid="non.test.sources"/>, by tasks that support this feature, or by FileSets.

Note that while the includes and excludes attributes accept multiple elements separated by commas or spaces, the nested <include> and <exclude> elements expect their name attribute to hold a single pattern.

The nested elements allow you to use if and unless arguments to specify that the element should only be used if a property is set, or that it should be used only if a property is not set.

For example

<patternset id="sources">

<include name="std/**/*.java"/>

<include name="prof/**/*.java" if="professional"/>

<exclude name="**/*Test*"/>

</patternset> will only include the files in the sub-directory prof if the property professional is set to some value.

The two sets

53/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<patternset includesfile="some-file"/> and

<patternset>

<includesfile name="some-file"/>

<patternset/> are identical. The include patterns will be read from the file some-file, one pattern per line.

<patternset>

<includesfile name="some-file"/>

<includesfile name="${some-other-file}"

if="some-other-file"

/>

<patternset/> will also read include patterns from the file the property some -other-file points to, if a property of that name has been defined.

7.3.22 Selectors

Selectors are a mechanism whereby the files that make up a fileset can be selected based on criteria other than filename as provided by the <include> and <exclude> tags.

7.3.22.1 HOW TO USE A SELECTOR

A selector is an element of FileSet, and appears within it. It can also be defined outside of any target by using the <selector> tag and then using it as a reference.

Different selectors have different attributes. Some selectors can contain other selectors, and these are called

Selector Containers

. There is also a category of selectors that allow user-defined extensions, called

Custom Selectors

. The ones built in to Ant are called

Core

Selectors

.

7.3.22.2 CORE SELECTORS

Core selectors are the ones that come standard with Ant. They can be used within a fileset and can be contained within Selector Containers.

The core selectors are:

• <contains> - Select files that contain a particular text string

• <date> - Select files that have been modified either before or after a particular date and time

• <depend> - Select files that have been modified more recently than equivalent files elsewhere

• <depth> - Select files that appear so many directories down in a directory tree

• <filename> - Select files whose name matches a particular pattern. Equivalent to the include and exclude elements of a patternset.

• <present> - Select files that either do or do not exist in some other location

• <size> - Select files that are larger or smaller than a particular number of bytes.

7.3.22.3 CONTAINS SELECTOR

The <contains> tag in a FileSet limits the files defined by that fileset to only those which contain the string specified by the text attribute.

54/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Attribute Description

text Specifies the text that every file must contain casesensitive Whether to pay attention to case when looking for the string in the text attribute. Default is true.

Here is an example of how to use the Contains Selector:

<fileset dir="${doc.path}" includes="**/*.html">

<contains text="script" casesensitive="no"/>

Required

Yes

No

</fileset>

Selects all the HTML files that contain the string script.

7.3.22.4 DATE SELECTOR

The <date> tag in a FileSet will put a limit on the files specified by the include tag, so that tags whose last modified date does not meet the date limits specified by the selector will not end up being selected.

Attribute Description Required

datetime Specifies the date and time to test for using a string of the format

MM/DD/YYYY HH:MM AM_or_PM. millis The number of milliseconds since 1970 that should be tested for. It is usually much easier to use the datetime attribute.

At least one of the two. granularity The number of milliseconds leeway to give before deciding whether a files modification time matches a date. This is needed because not every file system supports tracking the last modified time to the millisecond level. The file will be selected provided the condition could be true were the granularity added or subtracted from the actual time. Default is 0 milliseconds except on

Windows systems, where it is 2000 milliseconds (2 seconds).

No when Indicates how to interpret the date, whether the files to be selected are those No whose last modified times should be before, after, or equal to the specified value. Acceptable values for this attribute are: before - select files whose last modified date is before the indicated date after - select files whose last modified date is after the indicated date equal - select files whose last modified date is this exact date

The default is equal.

Here is an example of how to use the Date Selector:

<fileset dir="${jar.path}" includes="**/*.jar">

<date datetime="01/01/2001 12:00 AM" when="before"/>

</fileset>

Selects all JAR files which were last modified before midnight January 1, 2001.

7.3.22.5 DEPEND SELECTOR

The <depend> tag selects files whose last modified date is later than another, equivalent file in another location.

The <depend> tag supports the use of a contained

<mapper>

element to define the location of the file to be compared against. If no <mapper> element is specified, the identity type mapper is used.

The <depend> selector is case-sensitive.

55/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Attribute Description

targetdir The base directory to look for the files to compare against. The precise location depends on a combinatio n of this attribute and the <mapper> element, if any.

Required

Yes granularity The number of milliseconds leeway to give before deciding a file is out of date.

This is needed because not every file system supports tracking the last modified time to the millisecond level. Default is 0 milliseconds except on Windows systems, where it is 2000 milliseconds (2 seconds).

No

Here is an example of how to use the Depend Selector:

<fileset dir="${ant.1.5}/src/main" includes="**/*.java">

<depend targetdir="${ant.1.4.1}/src/main"/>

</fileset>

Selects all the Java source files which were modified in the 1.5 release.

7.3.22.6 DEPTH SELECTOR

The <depth> tag selects files based on how many directy levels deep they are in relation to the base directory of the fileset.

Attribute Description

min The minimum number of directory levels below the base directory that a file must be in order to be selected. Default is no limit. max The maximum number of directory levels below the base directory that a file can be and still be selected. Default is no limit.

Required

At least one of the two.

Here is an example of how to use the Depth Selector:

<fileset dir="${doc.path}" includes="**/*">

<depth max="1"/>

</fileset>

Selects all files in the base directory and one directory below that.

7.3.22.7 FILENAME SELECTOR

The <filename> tag acts like the <include> and <exclude> tags within a fileset. By using a selector instead, however, one can combine it with all the other selectors using whatever selector container is desired.

The <filename> selector is case-sensitive.

Attribute Description Required

name The name of files to select. The name parameter can contain the standard Ant wildcard characte rs.

Yes casesensitive Whether to pay attention to case when looking at file names. Default is negate

"true".

Whether to reverse the effects of this filename selection, therefore emulating an exclude rather than include tag. Default is "false".

No

No

Here is an example of how to use the Filename Selector:

56/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<fileset dir="${doc.path}" includes="**/*">

<filename name="**/*.css"/>

</fileset>

Selects all the cascading style sheet files.

7.3.22.8 PRESENT SELECTOR

The <present> tag selects files that have an equivalent file in another directory tree.

The <present> tag supports the use of a contained <mapper> element to define the location of the file to be tested against. If no <mapper> element is specified, the identity type mapper is used.

The <present> selector is case-sensitive.

Attribute Description Required

targetdir The base directory to look for the files to compare against. The precise location depends on a combination of this attribute and the <mapper> element, if any.

Yes present Whether we are requiring that a file is present in the src directory tree only, or in No both the src and the target directory tree. Valid values are: srconly - select files only if they are in the src directory tree but not in the target directory tree both - select files only if they are present both in the src and target directory trees

Default is both. Setting this attribute to "srconly" is equivalent to wrapping the selector in the <not> selector container.

Here is an example of how to use the Present Selector:

<fileset dir="${ant.1.5}/src/main" includes="**/*.java">

<present present="srconly" targetdir="${ant.1.4.1}/src/main"/>

</fileset>

Selects all the Java source files which are new in the 1.5 release.

7.3.22.9 SIZE SELECTOR

The <size> tag in a FileSet will put a limit on the files specified by the include tag, so that tags which do not meet the size limits specified by the selector will not end up being selected.

Attribute Description Required

Yes

No value The size of the file which should be tested for. units The units that the value attribute is expressed in. When using the standard single letter SI designations, such as "k","M", or "G", multiples of 1000 are used. If you want to use power of 2 units, use the IEC standard: "Ki" for 1024, "Mi" for

1048576, and so on. The default is no units, which means the value attribute expresses the exact number of bytes. when Indicates how to interpret the size, whether the files to be selected should be larger, smaller, or equal to that value. Acceptable values for this attribute are: less - select files less than the indicated size more - select files greater than the indicated size equal - select files this exact size

The default is equal.

Here is an example of how to use the Size Selector:

No

57/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<fileset dir="${jar.path}">

<patternset>

<include name="**/*.jar"/>

</patternset>

<size value="4" units="Ki" when="more"/>

</fileset>

Selects all JAR files that are larger than 4096 bytes.

7.3.22.10 SELECTOR CONT AINERS

To create more complex selections, a variety of selectors that contain other selectors are available for your use. They combine the selections of their child selectors in various ways.

The selector containers are:

• <and> - select a file only if all the contained selectors select it.

• <majority> - select a file if a majority of its selectors select it.

• <none> - select a file only if none of the contained selectors select it.

• <not> - can contain only one selector, and reverses what it selects and doesn't select.

• <or> - selects a file if any one of the contained selectors selects it.

• <selector> - contains only one selector and forwards all requests to it without alteration.

This is the selector to use if you want to define a reference. It is usable as an element of

<project>.

All selector containers can contain any other selector, including other containers, as an element. Using containers, the selector tags can be arbitrarily deep. Here is a complete list of allowable selector elements within a container:

• <and>

• <contains>

• <custom>

• <date>

• <depend>

<depth>

<filename>

<majority>

<none>

<not>

• <or>

• <present>

• <selector>

• <size>

7.3.22.11 AND SELECTOR

The <and> tag selects files that are selected by all of the elements it contains. It returns as soon as it finds a selector that does not select the file, so it is not guaranteed to check every selector.

Here is an example of how to use the And Selector:

<fileset dir="${dist}" includes="**/*.jar">

<and>

<size value="4" units="Ki" when="more"/>

<date datetime="01/01/2001 12:00 AM" when="before"/>

</and>

</fileset>

58/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Selects all the JAR file larger than 4096 bytes which haven't been update since the last millenium.

7.3.22.12 MAJORITY SELECTOR

The <majority> tag selects files provided that a majority of the contained elements also select it. Ties are dealt with as specified by the allowtie attribute.

Attribute Description Required

allowtie Whether files should be selected if there are an even number of selectors selecting them as are not selecting them. Default is true.

No

Here is an example of how to use the Majority Selector:

<fileset dir="${docs}" includes="**/*.html">

<majority>

<contains text="project" casesensitive="false"/>

<contains text="taskdef" casesensitive="false"/>

<contains text="IntrospectionHelper" casesensitive="true"/>

</majority>

</fileset>

Selects all the HTML files which contain at least two of the three phrases "project",

"taskdef", and "IntrospectionHelper" (this last phrase must match case exactly).

7.3.22.13 NONE SELECTOR

The <none> tag selects files that are not selected by any of the elements it contains. It returns as soon as it finds a selector that selects the file, so it is not guaranteed to check every selector.

Here is an example of how to use the None Selector:

<fileset dir="${src}" includes="**/*.java">

<none>

<present targetdir="${dest}"/>

<present targetdir="${dest}">

<mapper type="glob" from="*.java" to="*.class"/>

</present>

</none>

</fileset>

Selects only Java files which do not have equivalent java or class files in the dest directory.

7.3.22.14 NOT SELECTOR

The <not> tag reverses the meaning of the single selector it contains.

Here is an example of how to use the Not Selector:

<fileset dir="${src}" includes="**/*.java">

<not>

<contains text="test"/>

</not>

</fileset>

Selects all the files in the src directory that do not contain the string "test".

59/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

7.3.22.15 OR SELECTOR

The <or> tag selects files that are selected by any one of the elements it contains. It returns as soon as it finds a selector that selects the file, so it is not guaranteed to check every selector.

Here is an example of how to use the Or Selector:

<fileset dir="${basedir}">

<or>

<depth max="0"/>

<filename name="*.png"/>

<filename name="*.gif"/>

<filename name="*.jpg"/>

</or>

</fileset>

Selects all the files in the top directory along with all the image files below it.

7.3.22.16 SELECTOR REFERENCE

The <selector> tag is used to create selectors that can be reused through references. It is the only selector which can be used outside of any target, as an element of the <project> tag. It can contain only one other selector, but of course that selector can be a container.

Here is an example of how to use the Selector Reference:

<project default="all" basedir="./ant">

<selector id="completed">

<none>

<depend targetdir="build/classes">

<mapper type="glob" from="*.java" to="*.class"/>

</depend>

<depend targetdir="docs/manual/api">

<mapper type="glob" from="*.java" to="*.html"/>

</depend>

</none>

</selector>

<target>

<zip>

<fileset dir="src/main" includes="**/*.java">

<selector refid="completed"/>

</fileset>

</zip>

</target>

</project>

Zips up all the Java files which have an up-to-date equivalent class file and javadoc file associated with them.

7.3.22.17 CUSTOM SELECTORS

You can write your own selectors and use them within the selector containers by specifying them within the <custom> tag.

First, you have to write your selector class in Java. The only requirement it must meet in order to be a selector is that it implements the

60/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

org.apache.tools.ant.types.selectors.FileSelector

interface, which contains a single method. See Programming Selectors in Ant for more information.

Once that is written, you include it in your build file by using the <custom> tag.

Attribute Description

classname The name of your class that implements org.apache.tools.ant.types.selectors.FileSelector. classpath The classpath to use in order to load the custom selector class. If neither this classpath nor the classpathref are specified, the class will be loaded from the classpath that Ant uses. classpathref A reference to a classpath previously defined. If neither this reference nor the classpath above are specified, the class will be loaded from the classpath that

Ant uses.

Here is how you use <custom> to use your class as a selector:

<fileset dir="${mydir}" includes="**/*">

<custom classname="com.mydomain.MySelector">

<param name="myattribute" value="myvalue"/>

</custom>

</fileset>

Required

Yes

No

No

A number of core selectors can also be used as custom selectors by specifying their attributes using <param> elements. These are

• Contains Selector with classname org.apache.tools.ant.types.selectors.ContainsSelector

• Date Selector with classname org.apache.tools.ant.types.selectors.DateSelector

• Depth Selector with classname org.apache.tools.ant.types.selectors.DepthSelector

• Filename Selector with classname org.apache.tools.ant.types.selectors.FilenameSelector

• Size Selector with classname org.apache.tools.ant.types.selectors.SizeSelector

Here is the example from the Depth Selector section rewritten to use the selector through

<custom>

.

<fileset dir="${doc.path}" includes="**/*">

<custom classname="org.apache.tools.ant.types.selectors.DepthSelector">

<param name="max" value="1"/>

</custom>

</fileset>

Selects all files in the base directory and one directory below that.

For more details concerning writing your own selectors, consult Programming Selectors in

Ant .

7.3.23 XMLCatalog

An XMLCatalog is a catalog of public resources such as DTDs or entities that are referenced in an XML document. Catalogs are typically used to make web references to resources point to a locally cached copy of the resource.

61/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

This allows the XML Parser, XSLT Processor or other consumer of XML documents to efficiently allow a local substitution for a resource available on the web.

This data type provides a catalog of resource locations based on the OASIS "Open Catalog" standard . The catalog entries are used both for Entity resolution and URI resolution, in accordance with the org.xml.sax.EntityResolver and javax.xml.transform.URIResolver

interfaces as defined in the Java API for XML

Processing (JAXP) Specification .

For example, in a web.xml file, the DTD is referenced as:

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application

2.2//EN"

"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

The XML processor, without XMLCatalog support, would need to retrieve the DTD from the

URL specified whenever validation of the document was required.

This can be very time consuming during the build process, especially where network throughput is limited. Alternatively, you can do the following:

1. Copy web-app_2_2.dtd onto your local disk somewhere (either in the filesystem or even embedded inside a jar or zip file on the classpath).

2. Create an <xmlcatalog> with a <dtd> element whose location attribute points to the file.

3. Success! The XML processor will now use the local copy instead of calling out to the internet.

XMLCatalogs can appear inside tasks that support this feature or at the same level as target

- i.e., as children of project for reuse across different tasks, e.g. XML Validation and XSLT Transformation. The XML Validate task uses XMLCatalogs for entity resolution.

The XSLT Transformation task uses XMLCatalogs for both entity and URI resolution.

XMLCatalogs are specified as either a reference to another XMLCatalog, defined previously in a build file, or as a list of dtd or entity locations. A separate classpath for entity resolution may be specified inline via nested classpath elements; otherwise the system classpath is used for this as well.

XMLCatalogs can also be nested inside other XMLCatalogs. For example, a "superset"

XMLCatalog could be made by including several nested XMLCatalogs that referred to other, previously defined XMLCatalogs.

Currently, only <dtd> and <entity> elements may be specified inline; these roughly correspond to OASIS catalog entry types PUBLIC and URI respectively.

7.3.23.1 ENTITY/DTD/URI RESOLUTION ALGORITHM

When an entity, DTD, or URI is looked up by the XML processor, the XMLCatalog searches its list of entries to see if any match. That is, it attempts to match the publicId attribute of each entry with the PublicID or URI of the entity to be resolved. Assuming a matching entry is found, XMLCatalog then executes the following steps:

62/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

1. Filesystem lookup

The location is first looked up in the filesystem. If the location is a relative path, the ant project basedir attribute is used as the base directory. If the location specifies an absolute path, it is used as is. Once we have an absolute path in hand, we check to see if a valid and readable file exists at that path. If so, we are done. If not, we proceed to the next step.

2. Classpath lookup

The location is next looked up in the classpath. Recall that jar files are merely fancy zip files. For classpath lookup, the location is used as is (no base is prepended). We use a

Classloader to attempt to load the resource from the classpath. For example, if hello.jar is in the classpath and it contains foo/bar/blat.dtd it will resolve an entity whose location is foo/bar/blat.dtd

. Of course, it will not resolve an entity whose location is blat.dtd.

3. URL-space lookup

Finally, we attempt to make a URL out of the location. At first this may seem like this would defeat the purpose of XMLCatalogs -- why go back out to the internet? But in fact, this can be used to (in a sense) implement HTTP redirects, substituting one URL for another.

The mapped-to URL might also be served by a local web server. If the URL resolves to a valid and readable resource, we are done. Otherwise, we give up. In this case, the XML processor will perform its normal resolution algorithm. Depending on the processor configuration, further resolution failures may or may not result in fatal (i.e. build-ending) errors.

7.3.23.2 XMLCATALOG ATTRIBUTES

Attribute Description

id a unique name for an XMLCatalog, used for referencing the XMLCatalog's contents from another XMLCatalog

Required

No refid the id of another XMLCatalog whose contents you would like to be used for this

XMLCatalog

No

7.3.23.3 XMLCATALOG NESTED ELEMENTS

dtd/entity

The dtd and entity elements used to specify XMLCatalogs are identical in their structure

Attribute Description Required

publicId The public identifier used when defining a dtd or entity, e.g. "-//Sun

Microsystems, Inc.//DTD Web Application 2.2//EN"

Yes location The location of the local replacement to be used for the public identifier specified.

This may be specified as a file name, resource name found on the classpath, or a

URL. Relative paths will be resolved according to the base, which by default is

Yes the Ant project basedir.

classpath

The classpath to use for entity resolution . The nested <classpath> is a path -like structure.

Examples

Set up an XMLCatalog with a single dtd referenced locally in a user's home directory:

63/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<xmlcatalog>

<dtd

publicId="-//OASIS//DTD DocBook XML V4.1.2//EN"

location="/home/dion/downloads/docbook/docbookx.dtd"/>

</xmlcatalog>

Set up an XMLCatalog with a multiple dtds to be found either in the filesystem (relative to the Ant project basedir) or in the classpath:

<xmlcatalog id="commonDTDs">

<dtd

publicId="-//OASIS//DTD DocBook XML V4.1.2//EN"

location="docbook/docbookx.dtd"/>

<dtd

publicId="-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"

location="web-app_2_2.dtd"/>

</xmlcatalog>

Set up an XMLCatalog with a combination of DTDs and entities as well as a nested

XMLCatalog:

<xmlcatalog id="allcatalogs">

<dtd

publicId="-//ArielPartners//DTD XML Article V1.0//EN"

location="com/arielpartners/knowledgebase/dtd/article.dtd"/>

<entity

publicId="LargeLogo"

location="com/arielpartners/images/ariel-logo-large.gif"/>

<xmlcatalog refid="commonDTDs"/> </xmlcatalog>

To reference the above XMLCatalog in an xslt task:

<xslt basedir="${source.doc}"

destdir="${dest.xdocs}"

extension=".xml"

style="${source.xsl.converter.docbook}"

includes="**/*.xml"

force="true">

<xmlcatalog refid="allcatalogs"/>

</xslt>

7.4 Optional Types

7.4.1 ClassFileSet

A classfileset is a specialised type of fileset which, given a set of "root" classes, will include all of the class files upon which the root classes depend. This is typically used to create a jar with all of the required classes for a particular application. classfilesets are typically used by reference. They are declared with an "id" value and this is then used as a reference where a normal fileset is expected.

This type requires the jakarta-BCEL library.

64/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Attributes

The class fileset support the following attributes in addition to those supported by the standard fileset :

Attribute Description Required

rootclass A single root class name No

Nested Elements

Root

When more than one root class is required, multiple nested <root> elements may be used

Attribute Description Required

classname The fully qualified name of the root class Yes

RootFileSet

A root fileset is used to add a set of root classes from a fileset. In this case the entries in the fileset are expected to be Java class files. The name of the Java class is determined by the relative location of the classfile in the fileset. So, the file org/apache/tools/ant/Project.class corresponds to the Java class org.apache.tools.ant.Project.

Examples

<classfileset id="reqdClasses" dir="${classes.dir}">

<root classname="org.apache.tools.ant.Project" />

</classfileset>

This example creates a fileset containing all the class files upon which the org.apache.tools.ant.Project

class depends. This fileset could then be used to create a jar.

<jar destfile="minimal.jar">

<fileset refid="reqdClasses"/>

</jar>

<classfileset id="reqdClasses" dir="${classes.dir}">

<rootfileset dir="${classes.dir}" includes="org/apache/tools/ant/Project*.class"/>

</classfileset>

This example constructs the classfileset using all the class with names starting with Project in the org.apache.tools.ant package.

7.4.2 Extension

Utility type that represents either an available "Optional Package" (formerly known as

"Standard Extension") as described in the manifest of a JAR file, or the requirement for such an optional package.

Note that this type works with extensions as defined by the "Optional Package" specification. For more information about optional packages, see the document Optional

Package Versioning in the documentation bundle for your Java2 Standard Edition package, in file guide/extensions/versioning.html or online at http://java.sun.com/j2se/1.3/docs/guide/extensions/versioning.html

9 Core Tasks

9.1 Ant

Description

Runs Ant on a supplied buildfile. This can be used to build subprojects.

When the antfile attribute is omitted, the file "build.xml" in the supplied directory (dir attribute) is used.

If no target attribute is supplied, the default target of the new project is used.

By default, all of the properties of the current project will be available in the new project.

Alternatively, you can set the inheritAll attribute to false and only "user" properties (i.e., those passed on the command-line) will be passed to the new project. In either case, the set of properties passed to the new project will override the properties that are set in the new project (See also the property task ).

You can also set properties in the new project from the old project by using nested property tags. These properties are always passed regardless of the setting of inheritAll. This allows you to parameterize your subprojects. Properties defined on the command line can not be overridden by nested <property> elements.

References to data types can also be passed to the new project, but by default they are not.

If you set the inheritrefs attribute to true, all references will be copied, but they will not override references defined in the new project.

Nested

<reference>

elements can also be used to copy references from the calling project to the new project, optionally under a different id. References taken from nested elements will override existing references in the new project.

Inherited references are not available to top level tasks of the child project.

Parameters

Attribute Description antfile dir target the buildfile to use. Defaults to "build.xml". This file is expected to be a filename relative to the dir attribute given. the directory to use as a basedir for the new Ant project. Defaults to the current project's basedir, unless inheritall has been set to false, in which case it doesn't have a default value. This will override the basedir setting of the called project. the target of the new Ant project that should be executed. Defaults to the new project's default target. output Filename to write the ant output to. This is relative to the value of the dir attribute if it has been set or to the base directory of the current project otherwise. inheritAll If true, pass all properties to the new Ant project. Defaults to true. inheritRefsIf true, pass all references to the new Ant project. Defaults to false.

Parameters specified as nested elements property

74/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

See the description of the property task . Note that the refid attribute points to a reference in the calling project, not in the new one.

reference

Used to chose references that shall be copied into the new project, optionally changing their id.

Attribute Description Required refid The id of the reference in the calling project.

Yes torefid The id of the reference in the new project. No, defaults to the value of refid.

Basedir of the new project

The basedir value of the new project is affected by the two attributes dir and inheritall, see the following table for details:

new project's basedir dir attribute inheritAll

attribute value provided value provided true false value of dir attribute value of dir attribute omitted true false basedir of calling project (the one whose build file contains the

<ant> task). basedir attribute of the <project> element of the new project omitted

Examples

<ant antfile="subproject/subbuild.xml" dir="subproject" target="compile"/>

<ant dir="subproject"/>

<ant antfile="subproject/property_based_subbuild.xml">

<property name="param1" value="version 1.x"/>

<property file="config/subproject/default.properties"/>

</ant>

<ant inheritAll="false" antfile="subproject/subbuild.xml">

<property name="output.type" value="html"/>

</ant>

The build file of the calling pro ject defines some <path> elements like this:

<path id="path1">

...

</path>

<path id="path2">

...

</path> and the called build file (subbuild.xml) also defines a <path> with the id path1, but path2 is not defined:

<ant antfile="subbuild.xml" inheritrefs="true"/> will not override subbuild's definition of path1, but make the parent's definition of path2 available in the subbuild.

75/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<ant antfile="subbuild.xml"/> as well as

<ant antfile="subbuild.xml" inheritrefs="false"/> will neither override path1 nor copy path2.

<ant antfile="subbuild.xml" inheritrefs="false">

<reference refid="path1"/>

</ant> will override subbuild's definition of path1.

<ant antfile="subbuild.xml" inheritrefs="false">

<reference refid="path1" torefid="path2"/>

</ant> will copy the parent's definition of path1 into the new project using the id path2.

9.2 AntCall

Description

Call another target within the same build-file optionally specifying some properties (param's in this context)

By default, all of the properties of the current project will be available in the new project.

Alternatively, you can set the inheritAll attribute to false and only "user" properties (i.e., those passed on the command-line) will be passed to the new project. In either case, the set of properties passed to the new project will override the properties that are set in the new project (See also the property task ).

You can also set properties in the new project from the old project by using nested param tags. These properties are always passed regardless of the setting of inheritAll. This allows you to parameterize your subprojects. Properties defined on the command line can not be overridden by nested <param> elements.

Nested

<reference>

elements can be used to copy references from the calling project to the new project, optionally under a different id. References taken from nested elements will override existing references in the new project.

When a target is invoked by antcall, all of its dependent targets will also be called within the context of any new parameters. For example. if the target "doSomethingElse" depended on the target "init", then the antcall of "doSomethingElse" will call "init" during the call. Of course, any properties defined in the antcall task or inherited from the calling target will be fixed and not overridable in the init task -or indeed in the "doSomethingElse" task.

Parameters

Attribute Description target The target to execute.

Required

Yes

76/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

inheritAll If true, pass all properties to the new Ant project. Defaults to true. No inheritRefsIf true, pass all references to the new Ant project. Defaults to false. No

Note on inheritRefs

<antcall>

will not override existing references, even if you set inheritRefs to true. As the called build files is the same build file as the calling one, this means it will not override any reference set via an id attribute at all. The only references that can be inherited by the child project are those defined by nested <reference> elements or references defined by tasks directly (not using the id attribute).

Inherited references are not available to top level tasks of the child project.

Parameters specified as nested elements

param

Specifies the properties to set before running the specified target. See property for usage guidelines.

reference

Used to chose references that shall be copied into the new project, optionally changing their id.

Attribute Description Required

refid The id of the reference in the calling project. Yes torefid The id of the reference in the new project. No, defaults to the value of refid.

Examples

<target name="default">

<antcall target="doSomethingElse">

<param name="param1" value="value"/>

</antcall>

</target>

<target name="doSomethingElse">

<echo message="param1=${param1}"/>

</target>

Will run the target 'doSomethingElse' and echo 'param1=value'.

<antcall ... >

<reference refid="path1" torefid="path2"/>

</antcall> will copy the parent's definition of path1 into the new project using the id path2.

9.3 AntStructure

Description

Generates a DTD for Ant buildfiles which contains information about all tasks currently known to Ant.

77/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Note that the DTD generated by this task is incomplete, you can always add XML entities using

<taskdef>

or

<typedef>

. See here for a way to get around this problem.

This task doesn't know about required attributes, all will be listed as #IMPLIED.

Parameters

Attribute Description Required output file to write the DTD to.

Yes

Examples

<antstructure output="project.dtd"/>

9.4 Apply/ExecOn

The name execon is deprecated and only kept for backwards compatibility.

Description

Executes a system command. When the os attribute is specified, then the command is only executed when Ant is run on one of the specified operating systems.

The files and/or directories of a number of FileSet s are passed as arguments to the system command.

If you specify a nested mapper and the dest attribute, the timestamp of each source file is compared to the timestamp of a target file which is defined by the nested mapper element and searched for in the given dest.

At least one fileset is required, and you must not specify more than one mapper.

Parameters

Attribute executable dest dir relative

Description the command to execute without any command line arguments. the directory where the <apply> expects the target files will be placed by the command, when it is executed. the directory in which the command should be executed. whether the filenames should be passed on the command line as absolute or relative pathnames (relative to the base directory of the corresponding fileset for source files or the dest attribute for target files).

Required

Yes

Yes, if you specify a nested mapper

No

No, default is

false

No

No

No os output list of Operating Systems on which the command may be executed. the file to which the output of the command should be redirected. append whether output should be appended to or overwrite an existing file.

Defaults to false. If you set parallel to false, you will probably want to set this one to true. outputproperty the name of a property in which the output of the command should be stored. resultproperty the name of a property in which the return code of the command should be stored. Only of inte rest if failonerror=false. If you set timeout parallel to false, only the result of the first execution will be stored.

Stop the command if it doesn't finish within the specified time (given in milliseconds).

No

No

No

78/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

failonerror Stop the buildprocess if the command exits with a returncode other than 0. failifexecutionfailsStop the build if we can't start the program. Defaults to true.

No

No skipemptyfilesets Don't run the command, if no source files have been found or are newer than their corresponding target files. parallel type

Run the command only once, appending all files as arguments. If false, command will be executed once for every file. Defaults to false.

One of file, dir or both. If set to file, only the names of plain files will be sent to the command. If set to dir, only the names of directories are considered.

No, default is

false

No

No, default is

file newenvironment Do not propagate old environment when new environment variables are specified.

No, default is

false vmlauncher Run command using the Java VM's execution facilities where available. If set to false the underlying OS's shell, either directly or through the antRun scripts, will be used. Under some operating systems, this gives access to facilities not normally available through the VM including, under Windows, being able to execute scripts, rather than their associated interpreter. If you want to specify the name of the executable as a relative path to the directory given by the dir attribute, it may become necessary to set vmlauncher to false as well.

No, default is

true

Parameters specified as nested elements

fileset

You can use any number of nested <fileset> elements to define the files for this task and refer to <fileset>s defined elsewhere.

arg

Command line arguments should be specified as nested <arg> elements. See Command line arguments .

srcfile

By default the file names of the source files will be added to the end of the command line. If you need to place it somewhere different, use a nested <srcfile> element between your

<arg>

elements to mark the insertion point.

targetfile

<targetfile>

is similar to <srcfile> and marks the position of the target filename on the command line. If omitted, the target filenames will not be added to the command line at all.

This element can only be specified, if you also define a nested mapper and the dest attribute.

env

It is possible to specify environment variables to pass to the system command via nested

<env>

elements. See the description in the section about exec

Examples

<apply executable="ls">

<arg value="-l"/>

<fileset dir="/tmp">

<patternset>

<exclude name="**/*.txt"/>

</patternset>

</fileset>

79/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<fileset refid="other.files"/>

<arg value="arg1"/>

<srcfile/>

<arg value="arg2"/>

<fileset dir="/tmp"/>

</apply> invokes somecommand arg1 SOURCEFILENAME arg2 for each file in /tmp replacing

SOURCEFILENAME with the absolute filename of each file in turn. If parallel had been set to true, SOURCEFILENAME would be replaced with the absolute filenames of all files separated by spaces.

<apply executable="cc" dest="src/C" parallel="false">

<arg value="-c"/>

<arg value="-o"/>

<targetfile/>

<srcfile/>

<fileset dir="src/C" includes="*.c"/>

SOURCEFILE with the absolute name of the .c file.

9.5 Available

Description

Sets a property if a resource is available at runtime. This resource can be a file, a directory, a class in the classpath, or a JVM system resource.

If the resource is present, the property value is set to true by default; otherwise, the property is not set. You can set the value to something other than the default by specifying the value attribute.

Normally, this task is used to set properties that are useful to avoid target execution depending on system parameters.

9.6 Basename

Description

Task to determine the basename of a specified file, optionally minus a specified suffix.

When this task executes, it will set the specified property to the value of the last path element of the specified file. If file is a directory, the basename will be the last directory element. If file is a full-path, relative-path, or simple filename, the basename will be the simple file name, without any directory elements.

Defaults to "MD5". Other popular algorithms like "SHA" may be used as well.

Specifies the provider of the algorithm. No fileext property

The generated checksum file's name will be the original filename with

"." and fileext added to it. Defaults to the algorithm name being used.

This attribute can mean two different things, it depends on the presence of the verifyproperty attribute.

If you don't set the verifyproperty attribute , property specifies the name of the property to be set with the generated checksum value.

If you set the verifyproperty attribute, property specifies the checksum you expect to be generated (the checksum itself, not a name of a property containing the checksum).

This cannot be specified when fileext is being used or when the number of files for which checksums is to be generated is greater than 1. forceoverwrite Overwrite existing files even if the destination files are newer.

Defaults to "no". verifyproperty Specifies the name of the property to be set with "true" or "false" depending upon whether the generated checksum matches the existing checksum. When this is set, the generated checksum is not written to a file or property, but rather, the content of the file or property is used to check against the generated checksum. readbuffersize The size of the buffer )in bytes) to use when reading a file. Defaults to "8192" - you may get a better performance on big files if you increase this value.

Ant Manual 1.5.4 12/9/2003 7:47 PM

Parameters specified as nested elements

fileset

FileSets are used to select files to generate checksums for.

Examples

Example 1

<checksum file="foo.bar"/>

Generates a MD5 checksum for foo.bar and stores the checksum in the destination file foo.bar.MD5. foo.bar.MD5 is overwritten only if foo.bar is newer than itself.

Example 2

<checksum file="foo.bar" forceOverwrite="yes"/>

Generates a MD5 checksum for foo.bar and stores the checksum in foo.bar.MD5. If foo.bar.MD5 already exists, it is overwritten.

Example 3

<checksum file="foo.bar" property="foobarMD5"/>

Generates a MD5 checksum for foo.bar and stores it in the Project Property foobarMD5.

Example 4

<checksum file="foo.bar" verifyProperty="isMD5ok"/>

Generates a MD5 checksum for foo.bar, compares it against foo.bar.MD5 and sets isMD5ok to either true or false, depending upon the result.

Example 5

<checksum file="foo.bar" algorithm="SHA" fileext="asc"/>

Generates a SHA checksum for foo.bar and stores the checksum in the destination file foo.bar.asc. foo.bar.asc is overwritten only if foo.bar is newer than itself.

Example 6

<checksum file="foo.bar" property="${md5}" verifyProperty="isEqual"/>

Generates a MD5 checksum for foo.bar, compares it against the value of the property md5, and sets isEqual to either true or false, depending upon the result.

Example 7

<checksum>

<fileset dir=".">

<include name="foo*"/>

</fileset>

</checksum>

Works just like Example 1, but generates a .MD5 file for every file that begins with the name foo.

Example 8

<condition property="isChecksumEqual">

<checksum>

<fileset dir=".">

<include name="foo.bar"/>

</fileset>

</checksum>

</condition>

85/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Works like Example 4, but only sets isChecksumEqual to true, if the checksum matches - it will never be set to false. This example demonstrates use with the Condition task.

Note:

When working with more than one file, if condition and/or verifyproperty is used, the result will be true only if the checksums matched correctly for all files being considered.

9.11 Chmod

Description

Changes the permissions of a file or all files inside specified directories. Right now it has effect only under Unix. The permissions are also UNIX style, like the argument for the chmod command.

See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task holds an implicit FileSet and supports all of FileSet's attributes and nested elements directly. More FileSets can be specified using nested <fileset> elements.

Parameters

Attribute file dir perm includes

Description the file or single directory of which the permissions must be changed. the directory which holds the files whose permissions must be changed. the new permissions.

Required exactly one of the two or nested <fileset> elements.

Yes comma- or space-separated list of patterns of files that must be included.

No

No excludes comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted. defaultexcludes indicates whether default excludes should be used or not

("yes"/"no"). Default excludes are used when omitted. parallel process all specified files using a single chmod command.

Defaults to true. type One of file, dir or both. If set to file, only the permissions of plain files are going to be changed. If set to dir, only the directories are considered.

Examples

<chmod file="${dist}/start.sh" perm="ugo+rx"/>

No

No

No, default is file makes the "start.sh" file readable and executable for anyone on a UNIX system.

<chmod dir="${dist}/bin" perm="ugo+rx" includes="**/*.sh"/> makes all ".sh" files below ${dist}/bin readable and executable for anyone on a UNIX system.

<chmod perm="g+w">

<fileset dir="shared/sources1">

86/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<exclude name="**/trial/**"/>

</fileset>

<fileset refid="other.shared.sources"/>

</chmod> makes all files below shared/sources1 (except those below any directory named trial) writable for members of the same group on a UNIX system. In addition all files belonging to a FileSet with id other.shared.sources get the same permissions.

9.12 Concat

Description

Concatenates a file, or a series of files, to a single file or the console. The destination file will be created if it does not exist, though the the append attribute may be used to alter this behavior.

FileSet s and/or FileList s are used to select which files are to be concatenated. There is no singular 'file' attribute to specify a single file to cat -- a fileset or filelist must also be used in these cases.

Parameters

Attribute Description destfile The destination file for the concatenated stream. If not specified the console will be used instead. append Specifies whether or not the file specified by 'destfile' should be overwritten.

Defaults to "no".

Required

No

No encoding Specifies the encoding for the input files. Please see http://java.sun.com/products/jdk/1.2/docs/guide/internat/encoding.doc.html

for a list of possible values. Defaults to the platform's default character encoding.

No

Parameters specified as nested elements

fileset

FileSet s are used to select files to be concatenated. Note that the order in which the files selected from a fileset are concatenated is not guaranteed. If this is an issue, use multiple filesets or consider using filelists.

filelist

FileList s are used to select files to be concatenated. The file ordering in the files attribute will be the same order in which the files are concatenated.

Examples

Concatenate a string to a file:

<concat destfile="README">Hello, World!</concat>

Concatenate a series of files to the console:

<concat>

<fileset dir="messages" includes="*important*"/>

</concat>

Concatenate a single file, appending if the destination file exists:

<concat destfile="NOTES" append="true">

<filelist dir="notes" files="note.txt"/>

</concat>

87/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Concatenate a series of files, overwriting if the destination file exists:

<concat destfile="${docbook.dir}/all-sections.xml">

<filelist dir="${docbook.dir}/sections"

files="introduction.xml,overview.xml"/>

<fileset dir="${docbook.dir}"

includes="sections/*.xml"

excludes="introduction.xml,overview.xml"/>

</concat>

9.13 Condition

Description

Sets a property if a certain condition holds true - this is a generalization of Available and

Uptodate .

If the condition holds true, the property value is set to true by default; otherwise, the property is not set. You can set the value to something other than the default by specifying the value attribute.

Conditions are specified as nested elements , you must specify exactly one condition.

Parameters

Attribute Description property The name of the property to set.

Required

Yes value The value to set the property to. Defaults to "true".

No

Parameters specified as nested elements

All conditions to test are specified as nested elements, for a complete list see here .

Examples

<condition property="javamail.complete">

<and>

<available classname="javax.activation.DataHandler"/>

<available classname="javax.mail.Transport"/>

</and>

</condition> sets the property javamail.complete if both the JavaBeans Activation Framework and

JavaMail are available in the classpath.

<condition property="isMacOsButNotMacOsX">

<and>

<os family="mac"/>

<not>

<os family="unix"/>

</not>

</and>

</condition> sets the property isMacOsButNotMacOsX if the current operating system is MacOS, but not

MacOS X - which Ant considers to be in the Unix family as well.

88/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<condition property="isSunOSonSparc">

<os name="SunOS" arch="sparc"/>

</condition> sets the property isSunOSonSparc if the current operating system is SunOS and if it is running on a sparc architecture.

9.13.1 Conditions

These are the nested elements that can be used as conditions in the <condition> and

<waitfor> tasks.

# Condition Description

1 not

2

3 and or

The <not> element expects exactly one other condition to be nested into this element, negating the result of the condition. It doesn't have any attributes and accepts all nested elements of the condition task as nested elements as well.

The <and> element doesn't have any attributes and accepts an arbitrary number of conditions as nested elements - all nested elements of the condition task are supported. This condition is true if all of its contained conditions are, conditions will be evaluated in the order they have been specified in the build file.

The <and> condition has the same shortcut semantics as the Java && operator, as soon as one of the nested conditions is false, no other condition will be evaluated.

The <or> element doesn't have any attributes and accepts an arbitrary number of conditions as nested elements - all nested elements of the condition task are supported. This condition is true if at least one of its contained conditions is, conditions will be evaluated in the order they have been specified in the build file.

The <or> condition has the same shortcut semantics as the Java || operator, as soon as one of the nested conditions is true, no other condition will be evaluated.

4 available This condition is identical to the Available task, all attributes and nested elements of that task are supported, the property and value attributes are redundant and will be ignored.

5 uptodate This condition is identical to the Uptodate task, all attributes and nested elements of that task are supported, the property and value attributes are redundant and will be ignored.

6 os Test whether the current operating system is of a given type. Each defined attribute is tested and the result is true only if all the tests succeed.

Attribute Description Required family name

The name of the operating system family to expect.No

The name of the operating system to expect. No arch The architecture of the operating system to expect. No version The version of the operating system to expect. No

Supported values for the family attribute are:

9.14 Copy

Description

90/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Copies a file or FileSet to a new file or directory. By default, files are only copied if the source file is newer than the destination file, or when the destination file does not exist.

However, you can explicitly overwrite files with the overwrite attribute.

FileSet s are used to select a set of files to copy. To use a <fileset>, the todir attribute must be set.

Note: If you employ filters in your copy operation, you should limit the copy to text files.

Binary files will be corrupted by the copy operation. This applies whether the filters are implicitly defined by the filter task or explicitly provided to the copy operation as filtersets

Parameters

Attribute file

Description

The file to copy.

Required

Yes, unless a nested <fileset> element is used.

No; defaults to false. preservelastmodifiedGive the copied files the same last modified time as the original source files. (Note: Ignored on Java 1.1) tofile todir

The file to copy to.

The directory to copy to. overwrite filtering flatten

Overwrite existing files even if the destination files are newer.

Indicates whether token filtering using the global build-file filters should take place during the copy. Note: Nested

<filterset> elements will always be used, even if this attribute is not specified, or its value is false (no, or off).

Ignore the directory structure of the source files, and copy all files into the directory specified by the todir attribute.

Note that you can achieve the same effect by using a flatten mapper . includeEmptyDirs Copy any empty directories included in the FileSet(s). failonerror Log a warning message, but do not stop the build, when the file to copy does not exist. Only meaningful when copying a single file.

With the file attribute, either tofile or todir can be used. With nested <fileset> elements, if the set of files is greater than 1, or if only the dir attribute is specified in the <fileset>, or if the file attribute is also specified, then only todir is allowed.

No; defaults to false.

No; defaults to false.

No; defaults to false.

No; defaults to true.

No; defaults to true. verbose Log the files that are being copied. No; defaults to false. encoding The encoding to assume when filtercopying the files. since Ant 1.5.

No - defaults to default JVM encoding

Parameters specified as nested elements

fileset

FileSet s are used to select sets of files to copy. To use a fileset, the todir attribute must be set.

91/305

Ant Manual 1.5.4 12/9/2003 7:47 PM mapper

You can define filename transformations by using a nested mapper element. The default mapper used by <copy> is the identity mapper .

filterset

FilterSet s are used to replace tokens in files that are copied. To use a FilterSet, use the nested <filterset> element.

filterchain

The Copy task supports nested FilterChain s.

If <filterset> and <filterchain> elements are used inside the same <copy> task, all

<filterchain> elements are processed first followed by <filterset> elements.

Examples

Copy a single file

<copy file="myfile.txt" tofile="mycopy.txt"/>

Copy a single file to a directory

<copy file="myfile.txt" todir="../some/other/dir"/>

Copy a directory to another directory

<copy todir="../new/dir">

<fileset dir="src_dir"/>

</copy>

Copy a set of files to a directory

<copy todir="../dest/dir">

<fileset dir="src_dir">

<exclude name="**/*.java"/>

</fileset>

</copy>

<copy todir="../dest/dir">

<fileset dir="src_dir" excludes="**/*.java"/>

</copy>

Copy a set of files to a directory, appending .bak to the file name on the fly

<copy todir="../backup/dir">

<fileset dir="src_dir"/>

<mapper type="glob" from="*" to="*.bak"/>

</copy>

Copy a set of files to a directory, replacing @[email protected] with Foo Bar in all files.

<copy todir="../backup/dir">

<fileset dir="src_dir"/>

<filterset>

<filter token="TITLE" value="Foo Bar"/>

</filterset>

</copy>

Unix Note: File permissions are not retained when files are copied; they end up with the default UMASK permissions instead. This is caused by the lack of any means to query or set

92/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

file permissions in the current Java runtimes. If you need a permission-preserving copy function, use <exec executable="cp" ... > instead.

Windows Note: If you copy a file to a directory where that file already exists, but with different casing, the copied file takes on the case of the original. The workaround is to delete the file in the destination directory before you copy it.

9.15 Copydir – Deprecated

This task has been deprecated. Use the Copy task instead.

Description

Copies a directory tree from the source to the destination.

It is possible to refine the set of files that are being copied. This can be done with the

includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the

includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes src

) as well as the nested <include>, <exclude> and <patternset> elements.

Parameters

Attribute src dest includes

Description the directory to copy. the directory to copy to. comma- or space-separated list of patterns of files that must be included. All files are included when omitted.

Required

Yes

Yes

No

No

No includesfile excludes the name of a file. Each line of this file is taken to be an include pattern comma- or space-separated list of patterns of files that must be excluded.

No files (except default excludes) are excluded when omitted. excludesfile the name of a file. Each line of this file is taken to be an exclude pattern defaultexcludesindicates whether default excludes should be used or not ("yes"/"no"). filtering

Default excludes are used when omitted. indicates whether token filtering should take place during the copy

No

No

No

No flatten ignore directory structure of source directory, copy all files into a single directory, specified by the dest attribute (default is false). forceoverwrite overwrite existing files even if the destination files are newer (default is false).

Examples

No

<copydir src="${src}/resources"

dest="${dist}"

/> copies the directory ${src}/resources to ${dist}.

<copydir src="${src}/resources"

dest="${dist}"

includes="**/*.java"

93/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

excludes="**/Test.java"

/> copies the directory ${src}/resources to ${dist} recursively. All java files are copied, except for files with the name Test.java.

<copydir src="${src}/resources"

dest="${dist}"

includes="**/*.java"

excludes="mypackage/test/**"/> copies the directory ${src}/resources to ${dist} recursively. All java files are copied, except for the files under the mypackage/test directory.

9.16 Copyfile – Deprecated

This task has been deprecated. Use the Copy task instead.

Description

Copies a file from the source to the destination. The file is only copied if the source file is newer than the destination file, or when the destination file does not exist.

Parameters

Attribute Description src dest filtering the filename of the file to copy. the filename of the file where to copy to. indicates whether token filtering should take place during the copy forceoverwrite overwrite existing files even if the destination files are newer (default is false).

Examples

<copyfile src="test.java" dest="subdir/test.java"/>

<copyfile src="${src}/index.html" dest="${dist}/help/index.html"/>

9.17 Cvs

<cvs dest="${ws.dir}" command="update"/> updates the package/module that has previously been checked out into "${ws.dir}".

<cvs command="-q diff -u -N" output="patch.txt"/> silently (-q) creates a file called patch.txt which contains a unified (-u) diff which includes new files added via "cvs add" (-N) and can be used as input to patch. The equivalent, using

<commandline> elements, is:

<cvs output="patch">

<commandline>

<argument value="-q"/>

<argument value="diff"/>

<argument value="-u"/>

<argument value="-N"/>

You may include as many <commandline> elements as you like. Each will inherit the failonerror

, compression, and other "global" parameters from the <cvs> element.

<cvs command="update -A -d"/>

Updates from the head of repository ignoring sticky bits (-A) and creating any new directories as necessary (-d).

Note: the text of the command is passed to cvs "as-is" so any cvs options should appear before the command, and any command options should appear after the command as in the diff example above. See the cvs manual for details, specifically the Guide to CVS commands

9.18 CvsChangeLog

Description

Generates an XML-formatted report file of the change logs recorded in a CVS repository.

Important: This task needs "cvs" on the path. If it isn't, you will get an error (such as error

2 on windows). If <cvs> doesn't work, try to execute cvs.exe from the command line in the target directory in which you are working.

Parameters

Attribute Description dir The directory from which to run the CVS log command. destfile The file in which to write the change log report. usersfile Property file that contains name-value pairs mapping user IDs and names that should be used in the report in place of the user ID. daysinpast Sets the number of days into the past for which the change log information should be retrieved. start The earliest date from which change logs are to be included in the report.

Required

No; defaults to

${basedir}.

Yes

No

No

No end The latest date to which change logs are to be included in the report. No

Parameters specified as nested elements

user

The nested <user> element allows you to specify a mapping between a user ID as it appears on the CVS server and a name to include in the formatted report.

Generates an XML-formatted report file of the changes between two tags or dates recorded in a CVS repository.

Important: This task needs "cvs" on the path. If it isn't, you will get an error (such as error

2 on windows). If <cvs> doesn't work, try to execute cvs.exe from the command line in the target directory in which you are working.

Parameters

<cvstagdiff cvsRoot=":pserver:[email protected]:/home/cvspublic"

destfile="tagdiff.xml"

package="ant"

startTag="ANT_14"

endTag="ANT_141"

/>

Generates a tagdiff report for all the changes that have been made in the ant module between the tags ANT_14 and ANT_141. It writes these changes into the file tagdiff.xml.

<cvstagdiff

destfile="tagdiff.xml"

package="ant"

startDate="2002-01-01"

endDate="2002-31-01"

/>

Generates a tagdiff report for all the changes that have been made in the ant module in january 2002. In this example cvsRoot has not been set. The current cvsRoot will be used

(assuming the build is started from a folder stored in cvs. It writes these changes into the file tagdiff.xml.

Ant Manual 1.5.4 12/9/2003 7:47 PM

endDate="2002-31-01"

/>

Generates a tagdiff report for all the changes that have been made in the ant module in january 2002, with rootdir indicating that the actual location of the ant module in cvs is apache/ant

rather than ant. In this example cvsRoot has not been set. The current cvsRoot

will be used (assuming the build is started from a folder stored in cvs. It writes these changes into the file tagdiff.xml.

Generate Report

Ant includes a basic XSLT stylesheet that you can use to generate a HTML report based on the xml output. The following example illustrates how to generate a HTML report from the

XML report.

<style in="tagdiff.xml"

out="tagdiff.html"

style="${ant.home}/etc/tagdiff.xsl">

<param name="title" expression="Ant Diff"/>

<param name="module" expression="ant"/>

<param name="cvsweb" expression="http://cvs.apache.org/viewcvs/"/>

</style>

9.21 Delete

Description

Deletes a single file, a specified directory and all its files and subdirectories, or a set of files specified by one or more FileSet s. When specifying a set of files, empty directories are not removed by default. To remove empty directories, use the includeEmptyDirs attribute.

If you use this task to delete temporary files created by editors and it doesn't seem to work, read up on the default exclusion set in Directory-based Tasks, and see the defaultexcludes

attribute below.

Parameters

Attribute file dir

Description

The file to delete, specified as either the simple filename (if the file exists in the current base directory), a relative-path filename, or a full-path filename.

The directory to delete, including all its files and subdirectories.

Note: dir is not used to specify a directory name for file; file and dir are independent of each other.

WARNING: Do not set dir to ".", "${basedir}", or the fullpathname equivalent unless you truly intend to recursively remove

Required

At least one of the two, unless a <fileset> is specified.

100/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

verbose the entire contents of the current base directory (and the base directory itself, if different from the current working directory).

Show the name of each deleted file ("true"/"false"). Default is

"false" when omitted. quiet failonerror

If the specified file or directory does not exist, do not display a diagnostic message (unless Ant has been invoked with the -verbose or -debug switches) or modify the exit status to reflect an error. When set to "true", if a file or directory cannot be deleted, no error is reported. This setting emulates the -f option to the Unix rm command. Default is "false". Setting this to "true" implies setting failonerror to "false".

Controls whether an error (such as a failure to delete a file) stops the build or is merely reported to the screen. Only relevant if quiet is "false". Default is "true". includeEmptyDirs Set to "true" to delete empty directories when using filesets.

Default is "false". includes Deprecated. Use <fileset>. Comma- or space -separated list of patterns of files that must be deleted. All files are relative to the directory specified in dir. includesfile excludes

Deprecated. Use <fileset>. The name of a file. Each line of this file is taken to be an include pattern

Deprecated. Use <fileset>. Comma- or space -separated list of patterns of files that must be excluded from the deletion list. All files are relative to the directory specified in dir. No files (except default excludes) are excluded when omitted. excludesfile Deprecated. Use <fileset>. The name of a file. Each line of this file is taken to be an exclude pattern defaultexcludes Indicates whether default excludes should be used or not

("yes"/"no"). Default excludes are used when omitted.

Examples

<delete file="/lib/ant.jar"/> deletes the file /lib/ant.jar.

<delete dir="lib"/> deletes the lib directory, including all files and subdirectories of lib.

<delete>

<fileset dir="." includes="**/*.bak"/>

</delete> deletes all files with the extension .bak from the current directory and any subdirectories.

<delete includeEmptyDirs="true">

<fileset dir="build"/>

</delete> deletes all files and subdirectories of build, including build itself.

101/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

9.22 Deltree – Deprecated

This task has been deprecated. Use the Delete task instead.

Description

Deletes a directory with all its files and subdirectories.

Parameters

Attribute Description Required dir the directory to delete. Yes

Examples

<deltree dir="dist"/> deletes the directory dist, including its files and subdirectories.

<deltree dir="${dist}"/> deletes the directory ${dist}, including its files and subdirectories.

9.23 DependSet

A task to manage arbitrary dependencies between files.

Description

The dependset task compares a set of source files with a set of target files. If any of the source files is more recent than any of the target files, all of the target files are removed.

Source files and target files are specified via nested FileSets and/or nested FileLists .

Arbitrarily many source and target filesets/filelists may be specified, but at least one filelist/fileset is required for both sources and targets.

Use a FileSet when you want to use wildcard include or exclude patterns and don't care about missing files. Use a FileList when you want to consider the non-existence of a file as if it were out of date. If there are any non-existing files in any source or target FileList, all target files will be removed.

DependSet is useful to capture dependencies that are not or cannot be determined algorithmically. For example, the <style> task only compares the source XML file and XSLT stylesheet against the target file to determined whether to restyle the source. Using dependset you can extend this dependency checking to include a DTD or XSD file as well as other stylesheets imported by the main stylesheet.

Parameters

(none)

Parameters Specified as Nested Elements

srcfileset

The nested srcfileset element specifies a FileSet . All files included in this fileset will be compared against all files included in all of the targetfileset filesets and targetfilelist filelists. Multiple srcfileset filesets may be specified.

102/305

Ant Manual 1.5.4 12/9/2003 7:47 PM srcfilelist

The nested srcfilelist element specifies a FileList . All files included in this filelist will be compared against all files included in all of the targetfileset filesets and targetfilelist filelists. Multiple srcfilelist filelists may be specified.

targetfileset

The nested targetfileset element specifies a FileSet . All files included in this fileset will be compared against all files included in all of the srcfileset filesets and sourcefilelist filelists, and if any are older, they are all deleted.

targetfilelist

The nested targetfilelist element specifies a FileList . All files included in this filelist will be compared against all files included in all of the srcfileset filesets and sourcefilelist filelists, and if any are older, they are all deleted.

Examples

<dependset>

<srcfilelist

dir = "${dtd.dir}"

files = "paper.dtd,common.dtd"/>

<srcfilelist

dir = "${xsl.dir}"

files = "common.xsl"/>

<srcfilelist

dir = "${basedir}"

files = "build.xml"/>

<targetfileset

dir = "${output.dir}"

includes = "**/*.html"/>

</dependset>

In this example derived HTML files in the ${output.dir} directory will be removed if any are out-of-date with respect to:

1. the DTD of their source XML files

2. a common DTD (imported by the main DTD)

3. a subordinate XSLT stylesheet (imported by the main stylesheet), or

4. the buildfile

If any of the source files in the above example does not exist, all target files will also be removed. To ignore missing source files instead, use filesets instead of filelists for the source files.

9.24 Dirname

Description

Task to determine the directory path of a specified file.

When this task executes, it will set the specified property to the value of the specified file up to, but not including, the last path element. If the specified file is a path that ends in a filename, the filename will be dropped. If the specified file is just a filename, the directory will be the current directory.

Parameters

103/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Attribute Description Required file The path to take the dirname of. Yes property The name of the property to set. Yes

Examples

<dirname property="antfile.dir" file="${ant.file}"/> will set antfile.dir to the directory path for ${ant.file}.

<dirname property="foo.dirname" file="foo.txt"/> will set foo.dirname to the project's basedir.

9.25 Ear

Description

An extension of the Jar task with special treatment for files that should end up in an

Enterprise Application archive.

(The Ear task is a shortcut for specifying the particular layout of a EAR file. The same thing can be accomplished by using the prefix and fullpath attributes of zipfilesets in a Zip or Jar task.)

The extended zipfileset element from the zip task (with attributes prefix, fullpath, and src) is available in the Ear task.

Parameters

Attribute destfile appxml

Description the EAR file to create.

The deployment descriptor to use (META-INF/application.xml). basedir compress the directory from which to jar the files.

Not only store data but also compress them, defaults to true encoding filesonly includes

The character encoding to use for filenames inside the archive.

Defaults to UTF8. It is not recommended to change this value as

the created archive will most likely be unreadable for Java

otherwise.

Store only file entries, defaults to false comma- or space-separated list of patterns of files that must be included. All files are included when omitted. includesfile excludes excludesfile the name of a file. Each line of this file is taken to be an include pattern comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted. the name of a file. Each line of this file is taken to be an exclude pattern defaultexcludes indicates whether default excludes should be used or not

("yes"/"no"). Default excludes are used when omitted. manifest the manifest file to use.

104/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

update duplicate indicates whether to update or overwrite the destination file if it already exists. Default is "false". behavior when a duplicate file is found. Valid values are "add",

"preserve", and "fail". The default value is "add".

No

No

Nested elements metainf

The nested metainf element specifies a FileSet . All files included in this fileset will end up in the META-INF directory of the ear file. If this fileset includes a file named MANIFEST.MF, the file is ignored and you will get a warning.

Example

<ear destfile="${build.dir}/myapp.ear" appxml="${src.dir}/metadata/application.xml">

<fileset dir="${build.dir}" includes="*.jar,*.war"/>

</ear>

9.26 Echo

Description

Echoes a message to the current loggers and listeners which means System.out unless overridden. A level can be specified, which controls at what logging level the message is filtered at.

The task can also echo to a file, in which case the option to append rather than overwrite the file is available, and the level option is ignored

Parameters

Attribute Description message the message to echo. file the file to write the message to. append Append to an existing file? level

Examples

Control the level at which this message is reported.

One of "error", "warning", "info", "verbose", "debug"

<echo message="Hello, world"/>

<echo>This is a longer message stretching over two lines.

</echo>

<echo>

This is a longer message stretching over three lines; the first line is a blank

</echo>

Required

Yes, unless data is included in a character section within this element.

No

No - default is false.

No - default is "warning".

As XML parsers are wont to do, the first newline in the text element has been included in the text.

<echo message="Deleting drive C:" level="debug"/>

A message which only appears in -debug mode.

105/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<echo level="error">

Imminent failure in the antimatter containment facility.

Please withdraw to safe location at least 50km away.

</echo>

A message which appears even in -quiet mode.

<echo file="runner.csh" append="false">#\!/bin/tcsh java-1.3.1 -mx1024m ${project.entrypoint} $$*

Generate a shell script by echoing to a file. Note the use of a double $ symbol to stop Ant filtering out the single $ during variable expansion

9.27 Exec

Description

Executes a system command. When the os attribute is specified, then the command is only executed when Ant is run on one of the specified operating systems.

Cygwin Users

In general the <exec> task will not understand paths such as /bin/sh for the executable parameter. This is because the Java VM in which Ant is running is a Windows executable and is not aware of Cygwin conventions.

Parameters

Attribute command

Description the command to execute with all command line arguments.

deprecated, use executable and nested <arg> elements

instead.

Required

Exactly one of the two. executable dir the command to execute without any command line arguments. the directory in which the command should be executed. No os output list of Operating Systems on which the command may be executed. If the current OS's name is contained in this list, the command will be executed. The OS's name is determined by the Java Virtual machine and is set in the "os.name" system property. the file to which the output of the command should be redirected.

No

No append whether output should be appended to or overwrite an existing file.

Defaults to false. outputproperty the name of a property in which the output of the command should be stored. resultpro perty the name of a property in which the return code of the command should be stored. Only of interest if failonerror=false timeout Stop the command if it doesn't finish within the specified time (given in milliseconds). failonerror Stop the buildprocess if the command exits with a returncode other than 0. Defaults to false failifexecutionfails Stop the build if we can't start the program. Defaults to true. newenvironment Do not propagate old environment when new environment variables are specified.

No

No

No

No

No

No

No, default is false vmlauncher Run command using the Java VM's execution facilities where available.

If set to false the underlying OS's shell, either directly or through the

No, default is true

106/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

antRun scripts, will be used. Under some operating systems, this gives access to facilities not normally available through the VM including, under Windows, being able to execute scripts, rather than their associated interpreter. If you want to specify the name of the executable as a relative path to the directory given by the dir attribute, it may become necessary to set vmlauncher to false as well.

Examples

<exec dir="${src}" executable="cmd.exe" os="Windows 2000" output="dir.txt">

<arg line="/c dir"/>

</exec>

Parameters specified as nested elements

arg

Command line arguments should be specified as nested <arg> elements. See Command line arguments .

env

It is possible to specify environment variables to pass to the system command via nested

<env> elements.

Attribute Description key The name of the environment variable.

Required

Yes value The literal value for the environment variable. path The value for a PATH like environment variable. You can use ; or : as path separators and Ant will convert it to the platform's local conventions. file The value for the environment variable. Will be replaced by the absolute filename of the file by Ant.

Errors and return codes

Exactly one of these.

By default the return code of a <exec> is ignored; when you set failonerror="true" then any non zero response is treated as an error. Alternatively, you can set resultproperty to the name of a property and have it assigned to the result code (barring immutability, of course).

If the attempt to start the program fails with an OS dependent error code, then <exec> halts the build unless failifexecutionfails is set. You can use that to run a program if it exists, but otherwise do nothing.

What do those error codes mean? Well, they are OS dependent. On Windows boxes you have to look in include\error.h in your windows compiler or wine files; error code 2 means

'no such program', which usually means it is not on the path. Any time you see such an error from any ant task, it is usually not an ant bug, but some configuration problem on your machine.

Examples

<exec executable="emacs">

<env key="DISPLAY" value=":1.0"/>

</exec> starts emacs on display 1 of the X Window System.

<exec ... >

107/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<env key="PATH" path="${java.library.path}:${basedir}/bin"/>

</exec> adds ${basedir}/bin to the PATH of the system command.

Note: Although it may work for you to specify arguments using a simple arg-element and separate them by spaces it may fail if you switch to a newer version of the JDK. JDK < 1.2 will pass these as separate arguments to the program you are calling, JDK >= 1.2 will pass them as a single argument and cause most calls to fail.

Note2: If you are using Ant on Windows and a new DOS-Window pops up for every command which is executed this may be a problem of the JDK you are using. This problem may occur with all JDK's < 1.2.

Timeouts: If a timeout is specified, when it is reached the sub process is killed and a message printed to the log. The return value of the execution will be "-1", which will halt the build if failonerror=true, but be ignored otherwise.

9.28 Fail

Description

Exits the current build (just throwing a BuildException), optionally printing additional information.

The message of the Exception can be set via the message attribute or character data nested into the element.

Parameters

Attribute Description message A message giving further information on why the build exited

Required

No

No if Only fail if a property of the given name exists in the current project unless Only fail if a property of the given name doesn't exist in the current project No

Examples

<fail/> will exit the current build with no further information given.

BUILD FAILED build.xml:4: No message

<fail message="Something wrong here."/> will exit the current build and print something like the following to wherever your output goes:

BUILD FAILED build.xml:4: Something wrong here.

<fail>Something wrong here.</fail>

108/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

will give the same result as above.

9.29 Filter

Description

Sets a token filter for this project or read multiple token filter from an input file and sets these as filters. Token filters are used by all tasks that perform file copying operations through the Project commodity methods.

Note 1: the token string must not contain the separators chars (@).

Note 2: Either token and value attributes must be provided, or only the filtersfile attribute.

Parameters

Attribute Description

token the token string without @ value the string that should be put to replace the token when the file is copied filtersfile The file from which the filters must be read. This file must be a formatted as a property file.

* see notes 1 and 2 above parameters table.

Examples

<filter token="year" value="2000"/>

<copy todir="${dest.dir}" filtering="true">

<fileset dir="${src.dir}"/>

</copy>

Required

Yes*

Yes*

Yes* will copy recursively all the files from the src.dir directory into the dest.dir directory replacing all the occurrences of the string @[email protected] with 2000.

<filter filtersfile="deploy_env.properties"/> will read all property entries from the deploy_env.properties file and set these as filters.

9.30 FixCRLF

Description

Adjusts a text file to local conventions.

The set of files to be adjusted can be refined with the includes, includesfile, excludes,

excludesfile and defaultexcludes attributes. Patterns provided through the includes or

includesfile attributes specify files to be included. Patterns provided through the exclude or

excludesfile attribute specify files to be excluded. Additionally, default exclusions can be specified with the defaultexcludes attribute. See the section on directory based tasks , for details of file inclusion/exclusion patterns and their usage.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes srcdir

) as well as the nested <include>, <exclude> and <patternset> elements.

The output file is only written if it is a new file, or if it differs from the existing file. This prevents spurious rebuilds based on unchanged files which have been regenerated by this task.

Parameters

Attribute

srcDir destDir includes

Description

Where to find the files to be fixed up.

Where to place the corrected files. Defaults to srcDir (replacing the original file) comma- or space-separated list of patterns of files that must be included.

All files are included when omitted.

Required

Yes

No

No includesfile excludes the name of a file. Each line of this file is taken to be an include pattern comma- or space-separated list of patterns of files that must be excluded.

No files (except default excludes) are excluded when omitted. the name of a file. Each line of this file is taken to be an exclude pattern excludesfile defaultexcludes indicates whether default excludes should be used or not ("yes"/"no").

Default excludes are used when omitted. eol

No

No

No

No

Specifies how end-of-line (EOL) characters are to be handled. The EOL characters are CR, LF and the pair CRLF. Valid values for this property are: asis: leave EOL characters alone cr: convert all EOLs to a single CR lf: convert all EOLs to a single LF crlf: convert all EOLs to the pair CRLF

Default is based on the platform on which you are running this task. For

Unix platforms, the default is "lf". For DOS based systems (including

Windows), the default is "crlf". For Mac OS, the default is "cr".

This is the preferred method for specifying EOL. The "cr" attribute (see below) is now deprecated.

N.B.: One special case is recognized. The three characters CR-CR-LF are regarded as a single EOL. Unless this property is specified as "asis", this sequence will be converted into the specified EOL type.

No cr No javafiles tab

Deprecated. Specifies how CR characters are to be handled at end-of-line

(EOL). Valid values for this property are: asis: leave EOL characters alone. add: add a CR before any single LF characters. The intent is to convert all

EOLs to the pair CRLF. remove: remove all CRs from the file. The intent is to convert all EOLs to a single LF.

Default is based on the platform on which you are running this task. For

Unix platforms, the default is "remove". For DOS based systems (including

Windows), the default is "add".

N.B.: One special case is recognized. The three characters CR-CR-LF are regarded as a single EOL. Unless this property is specified as "asis", this sequence will be converted into the specified EOL type.

Used only in association with the "tab" attribute (see below), this boolean attribute indicates whether the fileset is a set of java source files

("yes"/"no"). Defaults to "no". See notes in section on "tab".

Specifies how tab characters are to be handled. Valid values for this property are: add: convert sequences of spaces which span a tab stop to tabs asis: leave tab and space characters alone remove: convert tabs to spaces

Default for this parameter is "asis".

N.B.: When the attribute "javafiles" (see above) is "true", literal TAB characters occurring within Java string or character constants are never modified. This functionality also requires the recognition of Java -style comments.

N.B.: There is an incompatibility between this and the previous version in the handling of white space at the end of lines. This version does not

No

No

TAB character interval. Valid values are between 2 and 80 inclusive. The default for this parameter is 8. eof Specifies how DOS end of file (control-Z) characters are to be handled.

Valid values for this property are: add: ensure that there is an EOF character at the end of the file asis: leave EOF characters alone remove: remove any EOF character found at the end

Default is based on the platform on which you are running this task. For

Unix platforms, the default is remove. For DOS based systems (including

Windows), the default is asis.

The encoding of the files. Defaults to default JVM encoding encoding

Examples

<fixcrlf srcdir="${src}"

eol="lf"

eof="remove"

includes="**/*.sh"

/>

No

No

No

Replaces EOLs with LF characters and removes eof characters from the shell scripts. Tabs and spaces are left as is.

<fixcrlf srcdir="${src}"

eol="crlf"

includes="**/*.bat"

/>

Replaces all EOLs with cr-lf pairs in the batch files. Tabs and spaces are left as is. EOF characters are left alone if run on DOS systems, and are removed if run on Unix systems.

<fixcrlf srcdir="${src}"

tab="add"

includes="**/Makefile"

/>

Sets EOLs according to local OS conventions, and converts sequences of spaces and tabs to the minimal set of spaces and tabs which will maintain spacing within the line. Tabs are set at 8 character intervals. EOF characters are left alone if run on DOS systems, and are removed if run on Unix systems. Many versions of make require tabs prior to commands.

<fixcrlf srcdir="${src}"

tab="remove"

tablength="3"

eol="lf"

javafiles="yes"

includes="**/*.java"

/>

Converts all EOLs in the included java source files to a single LF. Replace all TAB characters except those in string or character constants with spaces, assuming a tab width of 3. If run on a unix system, any CTRL-Z EOF characters at the end of the file are removed. On

DOS/Windows, any such EOF characters will be left untouched.

9.32 Get

Description

Gets a file fro m a URL. When the verbose option is "on", this task displays a '.' for every

100 Kb retrieved. Any URL schema supported by the runtime is valid here, including http:, ftp: and jar:; https: is only valid if the appropriate support is added to the pre-1.4 Java runtimes.

This task should be preferred above the CVS task when fetching remote content. CVS is significantly slower than loading a compressed archive compared to http/ftp.

The usetimestamp option enables you to control downloads so that the remote file is only fetched if newer than the local copy. If there is no local copy, the download always takes place. When a file is downloaded, the timestamp of the downloaded file is set to the remote timestamp, if the JVM is Java1.2 or later. NB: This timestamp facility only works on downloads using the HTTP protocol.

A username and password can be specified, in which case basic 'slightly encoded plain text' authentication is used. This is only a secure authentication mechanism over an HTTPS link.

If you need to go through a firewall, use <setproxy> to set up the proxy first.

Parameters

9.34 GZip / BZip2

See BZip2

9.35 Input

Description

Allows user interaction during the build process by prompting for input. To do so, it uses the configured InputHandler .

The prompt can be set via the message attribute or as character data nested into the element.

Optinonally a set of valid imput arguments can be defined via the validargs attribute. Input task will no accept value that don't match one of the predefined.

Optionally a property can be created from the value entered by the user. This property can then be used during the following build run. Input behaves according to property task which means that existing properties cannot be overriden.

Parameters

Attribute Description

message the Message which gets displayed to the user during the build run.

Required

No validargs comma separated String containing valid input arguments. If set, input task will reject any input not defined here. Validargs are compared case sensitive. If

No you want 'a' and 'A' to be accepted you will need to define both arguments within validargs. addproperty the name of a property to be created from input. Behaviour is equal to property task which means that existing properties cannot be overriden.

No

Examples

<input/>

Will pause the build run until return key is pressed when using the default InputHandler , the concrete behavior is defined by the InputHandler implementation you use.

<input>Press Return key to continue...</input>

Will display the message "Press Return key to continue..." and pause the build run until return key is pressed (again, the concrete behavior is implementation dependent).

<input

message="Press Return key to continue..."

114/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

/>

Will display the message "Press Return key to continue..." and pause the build run until return key is pressed (see above).

<input

message="All data is going to be deleted from DB continue (y/n)?"

validargs="y,n"

addproperty="do.delete"

/>

<condition property="do.abort">

<equals arg1="n" arg2="${do.delete}"/>

</condition>

<fail if="do.abort">Build aborted by user.</fail>

Will display the message "All data is going to be deleted from DB continue (y/n)?" and require 'y' to continue build or 'n' to exit build with following message "Build aborted by user.".

<input

message="Please enter db-username:"

addproperty="db.user"

/>

Will display the message "Please enter db-username:" and set the property db.user to the value entered by the user.

9.36 Jar

Description

Jars a set of files.

The basedir attribute is the reference directory from where to jar.

Note that file permissions will not be stored in the resulting jarfile.

It is possible to refine the set of files that are being jarred. This can be done with the

includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the

includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes basedir

) as well as the nested <include>, <exclude> and <patternset> elements.

You can also use nested file sets for more flexibility, and specify multiple ones to merge together different trees of files into one JAR. The extended fileset and groupfileset attributes from the zip task are also available in the jar task. See the Zip task for more details and examples.

115/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

If the manifest is omitted, a simple one will be supplied by Ant.

The update parameter controls what happens if the JAR file already exists. When set to yes, the JAR file is updated with the files specified. When set to no (the default) the JAR file is overwritten. An example use of this is provided in the Zip task documentation . Please note that ZIP files store file modification times with a granularity of two seconds. If a file is less than two seconds newer than the entry in the archive, Ant will not consider it newer.

(The Jar task is a shortcut for specifying the manifest file of a JAR file. The same thing can be accomplished by using the fullpath attribute of a zipfileset in a Zip task. The one difference is that if the manifest attribute is not specified, the Jar task will include an empty one for you.)

Manifests are processed by the Jar task according to the Jar file specification.

Note in particular that this may result in manifest lines greater than 72 bytes being wrapped and continued on the next line.

Parameters

Attribute

destfile basedir compress encoding filesonly includes

Description

the JAR file to create. the directory from which to jar the files.

Required

Yes

No

Not only store data but also compress them, defaults to true

The character encoding to use for filenames inside the archive. Defaults to UTF8. It is not recommended to change this value as the created archive will most likely be unreadable for Java otherwise.

Store only file entries, defaults to false

No

No

No comma- or space-separated list of patterns of files that must be included.

All files are included when omitted.

No includesfile excludes the name of a file. Each line of this file is taken to be an include pattern No comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted.

No excludesfile the name of a file. Each line of this file is taken to be an exclude pattern No defaultexcludes indicates whether default excludes should be used or not ("yes"/"no").

Default excludes are used when omitted.

No manifest update whenempty the manifest file to use. This can be either the location of a manifest, or the name of a jar added through a fileset. If its the name of an added jar,

No the task expects the manifest to be in the jar at META-INF/MANIFEST.MF indicates whether to update or overwrite the destination file if it already exists. Default is "false".

No behavior when no files match. Valid values are "fail", "skip", and "create".

Default is "skip".

No

No duplicate index behavior when a duplicate file is found. Valid values are "add",

"preserve", and "fail". The default value is "add". whether to create an index list to speed up classloading. This is a JDK

1.3+ specific feature. Defaults to false. manifestencoding The encoding used to read the JAR manifest, when a manifest file is specified. Defaults to the platform encoding.

Nested elements

metainf

No

No

116/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

The nested metainf element specifies a FileSet . All files included in this fileset will end up in the META-INF directory of the jar file. If this fileset includes a file named MANIFEST.MF, the file is ignored and you will get a warning.

manifest

The manifest nested element allows the manifest for the Jar file to be provided inline in the build file rather than in an external file. This element is identical to the manifest task, but the file and mode attributes must be omitted.

If both an inline manifest and an external file are both specified, the manifests are merged.

When using inline manifests, the Jar task will check whether the build file is more recent that the Jar file when deciding whether to rebuild the Jar. This will not take into account property file changes which may affect the resulting Jar.

Examples

<jar destfile="${dist}/lib/app.jar" basedir="${build}/classes"/> jars all files in the ${build}/classes directory into a file called app.jar in the ${dist}/lib directory.

<jar destfile="${dist}/lib/app.jar"

basedir="${build}/classes"

excludes="**/Test.class"

/> jars all files in the ${build}/classes directory into a file called app.jar in the ${dist}/lib directory. Files with the name Test.class are excluded.

<jar destfile="${dist}/lib/app.jar"

basedir="${build}/classes"

includes="mypackage/test/**"

excludes="**/Test.class"

/> jars all files in the ${build}/classes directory into a file called app.jar in the ${dist}/lib directory. Only files under the directory mypackage/test are used, and files with the name

Test.class

are excluded.

<jar destfile="${dist}/lib/app.jar">

<fileset dir="${build}/classes"

excludes="**/Test.class"

/>

<fileset dir="${src}/resources"/>

</jar> jars all files in the ${build}/classes directory and also in the ${src}/resources directory together into a file called app.jar in the ${dist}/lib directory. Files with the name

Test.class

are excluded. If there are files such as

${build}/classes/mypackage/MyClass.class

and

${src}/resources/mypackage/image.gif

, they will appear in the same directory in the

JAR (and thus be considered in the same package by Java).

117/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<jar destfile="test.jar" basedir=".">

<include name="build"/>

<manifest>

<attribute name="Built-By" value="${user.name}"/>

<section name="common/class1.class">

<attribute name="Sealed" value="false"/>

</section>

</manifest>

</jar>

This is an example of an inline manifest specification. Note that the Built-By attribute will take the value of the Ant property ${user.name}. The manifest produced by the above would look like this:

Manifest-Version: 1.0

Built-By: conor

Created-By: Apache Ant 1.5alpha

Name: common/class1.class

Sealed: false

9.37 Java

Description

Executes a Java class within the running (Ant) VM or forks another VM if specified.

If odd things go wrong when you run this task, set fork="true" to use a new JVM.

Parameters

Attribute

classname jar args classpath classpathref fork jvm jvmargs maxmemory failonerror dir output append

Description

the Java class to execute.

Required

Either jar or classname the location of the jar file to execute (must have a Main-Class entry in the manifest). Fork must be set to true if this option is selected.

Either jar or classname the arguments for the class that is executed. deprecated, use nested

<arg> elements instead.

No the classpath to use. No the classpath to use, given as reference to a PATH defined elsewhere. No if enabled triggers the class execution in another VM (disabled by default) the command used to invoke the Java Virtual Machine, default is

'java'. The command is resolved by java.lang.Runtime.exec().

Ignored if fork is disabled.

No

No the arguments to pass to the forked VM (ignored if fork is disabled).

deprecated, use nested <jvmarg> elements instead.

No

Max amount of memory to allocate to the forked VM (ignored if fork is No disabled)

Stop the buildprocess if the command exits with a returncode other than 0. Default is "false"

No

The directory to invoke the VM in. (ignored if fork is disabled)

Name of a file to write the output to.

No

No whether output should be appended to or overwrite an existing file. No

118/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Defaults to false. newenvironment Do not propagate old environment when new environment variables are specified. Default is "false" (ignored if fork is disabled).

No timeout Stop the command if it doesn't finish within the specified time (given in milliseconds). It is highly recommended to use this feature only if fork is enabled.

No

Parameters specified as nested elements

arg and jvmarg

Use nested <arg> and <jvmarg> elements to specify arguments for the Java class and the forked VM respectively. See Command line arguments .

sysproperty

Use nested <sysproperty> elements to specify system properties required by the class.

These properties will be made available to the VM during the execution of the class (either

ANT's VM or the forked VM). The attributes for this element are the same as for environment variables .

classpath

Java's classpath attribute is a PATH like structure and can also be set via a nested classpath element.

env

It is possible to specify environment variables to pass to the forked VM via nested env elements. See the description in the section about exec

Settings will be ignored if fork is disabled.

Examples

<java classname="test.Main">

<arg value="-h"/>

<classpath>

<pathelement location="dist/test.jar"/>

<pathelement path="${java.class.path}"/>

</classpath>

</java>

Run a class in this JVM with a new jar on the classpath

<java jar="dist/test.jar"

fork="true"

failonerror="true"

maxmemory="128m"

>

<arg value="-h"/>

<classpath>

<pathelement location="dist/test.jar"/>

<pathelement path="${java.class.path}"/>

</classpath>

</java>

Run the jar using the manifest supplied entry point, forking (as required), and with a maximum memory of 128MB. Any non zero return code breaks the build.

<java classname="test.Main"/>

119/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<java classname="test.Main"

fork="yes" >

<sysproperty key="DEBUG" value="true"/>

<arg value="-h"/>

<jvmarg value="-Xrunhprof:cpu=samples,file=log.txt,depth=3"/>

</java>

Note: you can not specify the (highly deprecated) MSJVM, "jview.exe" as the JVM, as it takes different parameters for other JVMs, That JVM can be started from <exec> if required.

9.38 Javac

Description

Compiles a Java source tree.

The source and destination directory will be recursively scanned for Java source files to compile. Only Java files that have no corresponding .class file or where the class file is older than the .java file will be compiled.

Note: Ant uses only the names of the source and class files to find the classes that need a rebuild. It will not scan the source and therefore will have no knowledge about nested classes, classes that are named different from the source file, and so on. See the

<depend> task for dependency checking based on other than just existence/modification times.

When the source files are part of a package, the directory structure of the source tree should follow the package hierarchy.

It is possible to refine the set of files that are being compiled. This can be done with the includes

, includesfile, excludes, and excludesfile attributes. With the includes or includesfile

attribute, you specify the files you want to have included. The exclude or excludesfile

attribute is used to specify the files you want to have excluded. In both cases, the list of files can be spec ified by either the filename, relative to the directory(s) specified in the srcdir attribute or nested <src> element(s), or by using wildcard patterns.

See the section on directory-based tasks , for information on how the inclusion/exclusion of files works, and how to write wildcard patterns.

It is possible to use different compilers. This can be specified by either setting the global build.compiler

property, which will affec t all <javac> tasks throughout the build, or by setting the compiler attribute, specific to the current <javac> task. Valid values for either the build.compiler property or the compiler attribute are:

• classic

(the standard compiler of JDK 1.1/1.2) – javac1.1 and javac1.2 can be used as aliases.

• modern

(the standard compiler of JDK 1.3/1.4) – javac1.3 and javac1.4 can be used as aliases.

• jikes

(the Jikes compiler).

• jvc

(the Command-Line Compiler from Microsoft's SDK for Java / Visual J++) – microsoft

can be used as an alias.

• kjc

(the kopi compiler).

• gcj

(the gcj compiler from gcc).

• sj

(Symantec java compiler) – symantec can be used as an alias.

120/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

• extJavac

(run either modern or classic in a JVM of its own).

The default is javac1.x with x depending on the JDK version you use while you are running

Ant. If you wish to use a different compiler interface than those supplied, you can write a class that implements the CompilerAdapter interface (package org.apache.tools.ant.taskdefs.compilers

). Supply the full classname in the build.compiler

property or the compiler attribute.

The fork attribute overrides the build.compiler property or compiler attribute setting and expects a JDK1.1 or higher to be set in JAVA_HOME.

You can also use the compiler attribute to tell Ant which JDK version it shall assume when it puts together the command line switches - even if you set fork="true". This is useful if you want to run the compiler of JDK 1.1 while you current JDK is 1.2+. If you use compiler="javac1.1"

and (for example) depend="true" Ant will use the command line switch -depend instead of -Xdepend.

This task will drop all entries that point to non-existent files/directories from the classpath it passes to the compiler.

Windows Note:When the modern compiler is used in unforked mode on Windows, it locks up the files present in the classpath of the <javac> task, and does not release them. The side effect of this is that you will not be able to delete or move those files later on in the build. The workaround is to fork when invoking the compiler.

Parameters

Attribute

srcdir destdir includes includesfile excludes excludesfile classpath sourcepath bootclasspath classpathref sourcepathref

Description

Location of the java files. (See the note below.)

No

The name of a file that contains a list of files to include (may be specified using wildcard patterns).

No

Comma- or space-separated list of files (may be specified using No wildcard patterns) that must be excluded; no files (except default excludes) are excluded when omitted.

The name of a file that contains a list of files to exclude (may be specified using wildcard patterns).

The classpath to use.

The sourcepath to use; defaults to the value of the srcdir attribute (or nested <src> elements). To suppress the sourcepath switch, use sourcepath="".

No

No

No

The classpath to use, given as a reference to a path defined elsewhere.

bootclasspathref elsewhere.

Location of bootstrap class files, given as a reference to a path defined elsewhere.

No extdirs encoding nowarn

No

No debug debuglevel optimize deprecation

Indicates whether source should be compiled with debug information; defaults to off. If set to off, -g:none will be passed

No on the command line for compilers that support it (for other compilers, no command line argument will be used). If set to true, the value of the debuglevel attribute determines the command line argument.

Keyword list to be appended to the -g command-line switch.

This will be ignored by all implementations except modern and classic(ver >= 1.2). Legal values are none or a commaseparated list of the following keywords: lines, vars, and source. If debuglevel is not specified, by default, nothing will be appended to -g. If debug is not turned on, this attribute will be ignored.

No

Indicates whether source should be compiled with deprecation information; defaults to off.

No target Generate class files for specific VM version (e.g., 1.1 or 1.2).

Note that the default value depends on the JVM that is running

Ant. In particular, if you use JDK 1.4 the generated classes will not be usable for a 1.1 Java VM unless you explicitly set this attribute to the value 1.1 (which is the default value for JDK 1.1 to 1.3).

Ant Manual 1.5.4 12/9/2003 7:47 PM

compiler all implementations except javac1.4 (or modern when Ant is not running in a 1.3 VM) and jikes.

If you use this attribute together with jikes, you must make sure that your version of jikes supports the -source switch.

Legal values are 1.3 and 1.4 – by default, no -source argument will be used at all.

The compiler implementation to use. If this attribute is not set, the value of the build.compiler property, if set, will be used.

Otherwise, the default compiler for the current VM will be used.

(See the above list of valid compilers.)

No listfiles Indicates whether the source files to be compiled will be listed; defaults to no.

No

Parameters specified as nested elements

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes srcdir) as well as the nested <include>, <exclude> and <patternset> elements.

src, classpath, sourcepath, bootclasspath and extdirs

<javac>'s srcdir, classpath, sourcepath, bootclasspath, and extdirs attributes are path-like structures and can also be set via nested <src>, <classpath>, <sourcepath>,

<bootclasspath> and <extdirs> elements, respectively.

compilerarg

You can specify additional command line arguments for the compiler with nested

<compilerarg> elements. These elements are specified like Command-line Arguments but have an additional attribute that can be used to enable arguments only if a given compiler implementation will be used.

Attribute Description Required

value line file path

See Command-line Arguments . compiler Only pass the specified argument if the chosen compiler implementation matches the value of this attribute. Legal values are the same as those in the above list of valid compilers.)

Examples

<javac srcdir="${src}"

Exactly one of these.

No

destdir="${build}"

classpath="xyz.jar"

debug="on"

/> compiles all .java files under the ${src} directory, and stores the .class files in the

${build}

directory. The classpath used includes xyz.jar, and compiling with debug information is on.

<javac srcdir="${src}"

destdir="${build}"

fork="true"

/>

123/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

compiles all .java files under the ${src} directory, and stores the .class files in the

${build}

directory. This will fork off the javac compiler using the default javac executable.

<javac srcdir="${src}"

destdir="${build}"

fork="java$$javac.exe"

/> compiles all .java files under the ${src} directory, and stores the .class files in the

${build}

directory. This will fork off the javac compiler, using the executable named java$javac.exe

. Note that the $ sign needs to be escaped by a second one.

<javac srcdir="${src}"

destdir="${build}"

includes="mypackage/p1/**,mypackage/p2/**"

excludes="mypackage/p1/testpackage/**"

classpath="xyz.jar"

debug="on"

/> compiles .java files under the ${src} directory, and stores the .class files in the ${build} directory. The classpath used includes xyz.jar, and debug information is on. Only files under mypackage/p1 and mypackage/p2 are used. All files in and below the mypackage/p1/testpackage

directory are excluded from compilation.

<javac srcdir="${src}:${src2}"

destdir="${build}"

includes="mypackage/p1/**,mypackage/p2/**"

excludes="mypackage/p1/testpackage/**"

classpath="xyz.jar"

debug="on"

/> is the same as the previous example, with the addition of a second source path, defined by the property src2. This can also be represented using nested <src> elements as follows:

<javac destdir="${build}"

classpath="xyz.jar"

debug="on">

<src path="${src}"/>

<src path="${src2}"/>

<include name="mypackage/p1/**"/>

<include name="mypackage/p2/**"/>

<exclude name="mypackage/p1/testpackage/**"/>

</javac>

If you want to run the javac compiler of a different JDK, you should tell Ant, where to find the compiler and which version of JDK you will be using so it can choose the correct command line switches. The following example executes a JDK 1.1 javac in a new process and uses the correct command line switches even when Ant is running in a Java VM of a different version:

<javac srcdir="${src}"

124/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

destdir="${build}"

fork="yes"

executable="/opt/java/jdk1.1/bin/javac"

compiler="javac1.1"

/>

Note: If you wish to compile only source files located in certain packages below a common root, use the include/exclude attributes or <include>/<exclude> nested elements to filter for these packages. Do not include part of your package structure in the srcdir attribute

(or nested <src> elements), or Ant will recompile your source files every time you run your compile target. See the Ant FAQ for additional information.

Note: If you are using Ant on Windows and a new DOS window pops up for every use of an external compiler, this may be a problem of the JDK you are using. This problem may occur with all JDKs < 1.2.

Jikes Notes

Jikes supports some extra options, which can be set be defining the properties shown below prior to invoking the task. The setting for each property will be in affect for all <javac> tasks throughout the build. The Ant developers are aware that this is ugly and inflexible – expect a better solution in the future. All the options are boolean, and must be set to true or yes to be interpreted as anything other than false. By default, build.compiler.warnings is true, while all others are false.

Property

build.compiler.emacs

Description Default

Enable emacs -compatible error messages. false false build.compiler.fulldepend build.compiler.pedantic

Enable full dependency checking; see the +F switch in the Jikes manual.

Enable pedantic warnings. build.compiler.warnings

Deprecated.

Use <javac>'s nowarn attribute instead.

Don't disable warning messages.

9.39 Javadoc/Javadoc2

Description

Generates code documentation using the javadoc tool. false true

The source directory will be recursively scanned for Java source files to process but only those matching the inclusion rules, and not matching the exclusions rules will be passed to the javadoc tool. This allows wildcards to be used to choose between package names, reducing verbosity and management costs over time. This task, however, has no notion of

"changed" files, unlike the javac task. This means all packages will be processed each time this task is run. In general, however, this task is used much less frequently.

This task works seamlessly between different javadoc versions (1.1, 1.2 and 1.4), with the obvious restriction that the 1.2 attributes will be ignored if run in a 1. 1 VM.

NOTE: since javadoc calls System.exit(), javadoc cannot be run inside the same VM as ant without breaking functionality. For this reason, this task always forks the VM. This overhead is not significant since javadoc is normally a heavy application and will be called infrequently.

125/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

NOTE: the packagelist attribute allows you to specify the list of packages to document outside of the Ant file. It's a much better practice to include everything inside the build.xml file. This option was added in order to ma ke it easier to migrate from regular makefiles, where you would use this option of javadoc. The packages listed in packagelist are not checked, so the task performs even if some packages are missing or broken. Use this option if you wish to convert from an existing makefile. Once things are running you should then switch to the regular notation.

DEPRECATION: the javadoc2 task simply points to the javadoc task and it's there for back compatibility reasons. Since this task will be removed in future versions, you are strongly encouraged to use javadoc

instead.

Also applies to the package names specified via the packagenames attribute or nested package elements. (yes | no). Default is no.

No source Necessary to enable javadoc to handle assertions present in J2SE v 1.4 source code.

Set this to "1.4" to documents code that compiles using "javac -source 1.4".

1.4 No

Format of the group attribute

The arguments are comma-delimited. Each single argument is 2 space-delimited strings, where the first one is the group's title and the second one a colon delimited list of packages.

If you need to specify more than one group, or a group whose title contains a comma or a space character, using nested group elements is highly recommended.

E.g.,

group="XSLT_Packages org.apache.xalan.xslt*,XPath_Packages org.apache.xalan.xpath*"

Parameters specified as nested elements

# Parameter Description

1 packageset A DirSet . All matched directories that contain Java source files will be passed to javadoc as package names. Package names are created from the directory names by translating the directory separator into dots. Ant assumes the base directory of the packageset points to the root of a package hierarchy.

The packagenames, excludepackagenames and defaultexcludes attributes of the task have no effect on the nested <packageset> elements.

2 fileset

3 package

A FileSet . All matched files will be passed to javadoc as source files. Ant will automatically add the include pattern **/*.java to these filesets.

Nested filesets can be used to document sources that are in the default package or if you want to exclude certain files from documentation. If you want to document all source files and don't use the default package, packagesets should be used instead as this increases javadocs performance.

The packagenames, excludepackagenames and defaultexcludes attributes of the task have no effect on the nested <fileset> elements.

Same as one entry in the list given by packagenames.

Parameters:

Attribute Description Required

name The package name (may be a wildcard) Yes

4 excludepackage Same as one entry in the list given by excludepackagenames.

Parameters:

Same as for package

5 source Same as one entry in the list given by sourcefiles.

Parameters

Attribute Description Required

6

7 doctitle header file The source file to document Yes

Same as the doctitle attribute, but you can nest text inside the element this way.

Similar to <doctitle>.

Create link to javadoc output at the given URL. This performs the same role as the link and linkoffline attributes. You can use either syntax (or both at once), but with the nested elements you can easily specify multiple occurrences of the arguments.

Parameters

Attribute Description Required

href offline

The URL for the external documentation you wish to link to

True if this link is not available online at the time of generating the documentation

Yes

No packagelistLoc The location to the directory containing the package-list file for the external

Only if the offline attribute is true documentation

Separates packages on the overview page into whatever groups you specify, one group per table. This performs the same role as the group attribute. You can use either syntax (or both at once), but with the nested elements you can easily specify multiple occurrences of the arguments.

Parameters

Attribute Description Required

title Title of the group packages List of packages to include in that group.

Multiple packages are separated with ':'.

Yes, unless nested

<title> given

Yes, unless nested

<package>s given

The title may be specified as a nested <title> element with text contents, and the packages may be listed with nested <package> elements as for the main task.

The doclet nested element is used to specify the doclet that javadoc will use to process the input source files. A number of the standard javadoc arguments are actually arguments of the standard doclet. If these are specified in the javadoc task's attributes, they will be passed to the doclet specified in the <doclet> nested element. Such attributes should only be specified, therefore, if they can be interpreted by the doclet in use.

If the doclet requires additional parameters, these can be specified with

<param> elements within the <doclet> element. These paramaters are restricted to simple strings. An example usage of the doclet element is shown below:

<javadoc ... >

<doclet name="theDoclet"

path="path/to/theDoclet">

<param name=" -foo" value="foovalue"/>

<param name=" -bar" value="barvalue"/>

</doclet>

</javadoc>

The tag nested element is used to specify custom tags. This option is only available with Java 1.4.

Parameters

Attribute Description Required

name Name of the tag (e.g. todo) description Description for tag (e.g. To do:)

Yes

Yes

129/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

scope Scope for the tag - the elements in which it can be used. This is a comma separated list of some of the elements: overview, packages, types, constructors,

No

14 taglet The ta glet nested element is used to specify custom taglets. This option is only available with Java 1.4.

Parameters

Attribute Description

name The name of the taglet class (e.g. com.sun.tools.doclets.ToDoTaglet)

Required

Yes

15 sourcepath, classpath and bootclasspath

Example

path A path specifying the search path for the taglet class

(e.g. /home/taglets). The path may also be specified

No by a nested <path> element

Javadoc's sourcepath, classpath and bootclasspath attributes are PATH like structure and can also be set via nested sourcepath, classpath and bootclasspath elements respectively.

9.43 Manifest

Description

Creates a manifest file.

This task can be used to write a Manifest file, optionally replacing or updating an existing file.

134/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Manifests are processed according to the Jar file specification.

. Specifically, a manifest element consists of a set of attributes and sections. These sections in turn may contain attributes. Note in particular that this may result in manifest lines greater than 72 bytes being wrapped and continued on the next line.

Parameters

Attribute Description Required

file the manifest-file to create/update. Yes mode One of "update" or "replace", default is "replace". No encoding The encoding used to read the existing manifest when updating.

No, defaults to UTF-8 encoding.

Nested elements

attribute

One attribute for the manifest file. Those attributes that are not nested into a section will be added to the "Main" section.

Attribute Description Required

name value the name of the attribute. Yes the value of the attribute. Yes

section

A manifest section - you can nest attribute elements into sections.

Attribute Description Required

name the name of the section. No, if omitted it will be assumed to be the main section.

Examples

<manifest file="MANIFEST.MF">

<attribute name="Built-By" value="${user.name}"/>

<section name="common">

<attribute name="Specification-Title" value="Example"/>

<attribute name="Specification-Version" value="${version}"/>

<attribute name="Specification-Vendor" value="Example Organization"/>

<attribute name="Implementation-Title" value="common"/>

<attribute name="Implementation-Version" value="${version} ${TODAY}"/>

<attribute name="Implementation-Vendor" value="Example Corp."/>

</section>

<section name="common/class1.class">

<attribute name="Sealed" value="false"/>

</section>

</manifest>

Creates or replaces the file MANIFEST.MF. Note that the Built-By attribute will take the value of the Ant property ${user.name}. The same is true for the ${version} and

${TODAY} properties. This example produces a MANIFEST.MF that contains package version identification for the package common.

The manifest produced by the above would look like this:

Manifest-Version: 1.0

Built-By: bodewig

Created-By: Apache Ant 1.5alpha

135/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Name: common

Specification-Title: Example

Specification-Vendor: Example Organization

Implementation-Vendor: Example Corp.

Specification-Version: 1.1

Implementation-Version: 1.1 February 19 2002

Implementation-Title: common

Name: common/class1.class

Sealed: false

9.44 Mkdir

Description

Creates a directory. Also non-existent parent directories are created, when necessary.

Parameters

Attribute Description Required

dir the directory to create. Yes

Examples

<mkdir dir="${dist}"/> creates a directory ${dist}.

<mkdir dir="${dist}/lib"/> creates a directory ${dist}/lib.

9.45 Move

Description

Moves a file to a new file or directory, or sets of files to a new directory. By default, the destination file is overwritten if it already exists. When overwrite is turned off, then files are only moved if the source file is newer than the destination file, or when the destination file does not exist.

FileSet s are used to select sets of files to move to the todir directory.

Parameters

Attribute Description Required

file the file to move One of file or at least one nested fileset element

No; defaults to false. preservelastmodified Give the moved files the same last modified time as the original source files. (Note: Ignored on Java 1.1) tofile todir the file to move to the directory to move to overwrite overwrite existing files even if the

With the file attribute, either tofile or todir can be used. With nested filesets, if the fileset size is greater than 1 or if the only entry in the fileset is a directory or if the file attribute is already specified, only todir is allowed

No

136/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

filtering flatten destination files are newer (default is

"true") indicates whether token filtering should take place during the move. See the filter task for a description of how filters work.

No ignore directory structure of source directory, copy all files into a single directory, specified by the todir attribute (default is "false").Note that you can achieve the same effect by using a flatten mapper

No includeEmptyDirs Copy empty directories included with the nested FileSet(s). Defaults to "yes".

No failonerror Log a warning message, but do not stop No; defaults to true. the build, when the file to move does not exist. Only meaningful when moving a single file. verbose Log the files that are being moved. No; defaults to false. encoding The encoding to assume when filtermoving the files. since Ant 1.5.

No - defaults to default JVM encoding

Parameters specified as nested elements mapper

You can define file name transformations by using a nested mapper element. The default mapper used by <copy> is the identity .

filterchain

The Move task supports nested FilterChain s.

If <filterset> and <filterchain> elements are used inside the same <move> task, all

<filterchain> elements are processed first followed by <filterset> elements.

Examples

Move a single file (rename a file)

<move file="file.orig" tofile="file.moved"/>

Move a single file to a directory

<move file="file.orig" todir="dir/to/move/to"/>

Move a directory to a new directory

<move todir="new/dir/to/move/to">

<fileset dir="src/dir"/>

</move>

Move a set of files to a new directory

<move todir="some/new/dir">

<fileset dir="my/src/dir">

<include name="**/*.jar"/>

<exclude name="**/ant.jar"/>

</fileset>

</move>

Append ".bak" to the names of all files in a directory.

137/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<move todir="my/src/dir">

<fileset dir="my/src/dir">

<exclude name="**/*.bak"/>

</fileset>

<mapper type="glob" from="*" to="*.bak"/>

</move>

9.46 Parallel

Description

Parallel is a container task - it can contain other Ant tasks. Each nested task within the parallel task will be executed in its own thread.

Parallel tasks have a number of uses in an Ant build file including:

• Taking advantage of available processing resources to reduce build time

• Testing servers, where the server can be run in one thread and the test harness is run in another thread.

Care must be taken when using multithreading to ensure the tasks within the threads do not interact. For example, two javac compile tasks which write classes into the same destination directory may interact where one tries to read a class for dependency information while the other task is writing the class file. Be sure to avoid these types of interactions within a <parallel> task

The parallel task has no attributes and does not support any nested elements apart from

Ant tasks. Any valid Ant task may be embedded within a parallel task, including other parallel tasks.

Note that while the tasks within the parallel task are being run, the main thread will be blocked waiting for all the child threads to complete.

If any of the tasks within the <parallel> task fails, the remaining tasks in other threads will continue to run until all threads have completed. In this situation, the parallel task will also fail.

The parallel task may be combined with the sequential task to define sequences of tasks to be executed on each thread within the parallel block

Examples

<parallel>

<wlrun ... >

<sequential>

<sleep seconds="30"/>

<junit ... >

<wlstop/>

</sequential>

</parallel>

This example represents a typical pattern for testing a server application. In one thread the server is started (the wlrun task). The other thread consists of a three tasks which are performed in sequence. The sleep task is used to give the server time to come up. Another task which is capable of validating that the server is available could be used in place of the sleep task. The test harness is then run. Once the tests are complete, the server is stopped

138/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

(using wlstop in this example), allowing both threads to complete. The parallel task will also complete at this time and the build will then continue.

<parallel>

<javac ...> <!-- compiler servlet code -->

<wljspc ...> <!-- precompile JSPs -->

</parallel>

This example shows two independent tasks being run to achieve better resource utilization during the build. In this instance, some servlets are being compiled in one thead and a set of JSPs is being precompiled in another. As noted above, you need to be careful that the two tasks are independent, both in terms of their dependencies and in terms of their potential interactions in Ant's external environment.

9.47 Patch

Description

Applies a diff file to originals. ; requires "patch" to be on the execution path.

Parameters

Attribute

patchfile

Description

the file that includes the diff output

Required

Yes originalfile the file to patch backups quiet

<patch patchfile="module.1.0-1.1.patch" strip="1"/> like above but one leading directory part will be removed. i.e. if the diff output looked like

--- a/mod1.0/A Mon Jun 5 17:28:41 2000

+++ a/mod1.1/A Mon Jun 5 17:28:49 2000 the leading a/ will be stripped.

9.48 Pathconvert

Description

139/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Converts a nested <path> or reference to a Path, FileSet, DirSet, or FileList into a path form for a particular platform, and stores the result in a given property. It can also be used when you need to convert a Path, FileSet, or DirSet into a list, separated by a given character, such as a comma or space, or, conversely, to convert a list of files in a FileList into a path.

Nested <map> elements can be specified to map Windows drive letters to Unix paths, and vice-versa.

Parameters

'netware' or 'os/2'. This is a shorthand mechanism for specifying both pathsep and dirsep according to the specified target architecture. dirsep The character(s) to use as the directory separator in the generated paths. pathsep The character(s) to use as the path-element separator in the generated paths. property The name of the property in which to place the converted path.

Required

Yes, unless pathsep and/or dirsep are specified.

No, defaults to current JVM

File.separator

No, defaults to current JVM

File.pathSeparator

Yes refid What to convert, given as a reference to a <path>,

<fileset>, <dirset>, or <filelist> defined elsewhere setonempty Should the property be set, even if the result is the empty string?

Parameters specified as nested elements

map

Specifies the mapping of path prefixes between Unix and Windows.

Attribute Description

No; if omitted, a nested

<path> element must be supplied.

No; default is "true".

Required

From The prefix to match. Note that this value is case-insensitive when the build is running on a Windows platform and case-sensitive when running on a Unix platform.

The replacement text to use when from is matched.

Yes

To Yes

Each map element specifies a single replacement map to be applied to the elements of the path being processed. If no map entries are specified, then no path prefix mapping is performed.

Note: The map elements are applied in the order specified, and only the first matching map element is applied. So, the ordering of your map elements can be important, if any from values are prefixes of other from values.

path

If the refid attribute is not specified, then a nested <path> element must be supplied. See

Path-like Structures for details.

Examples

In the examples below, assume that the ${wl.home} property has the value d:\weblogic, and ${wl.home.unix} has the value /weblogic.

140/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Example 1

<path id="wl.path">

<pathelement location="${wl.home}/lib/weblogicaux.jar"/>

<pathelement location="${wl.home}/classes"/>

<pathelement location="${wl.home}/mssqlserver4/classes"/>

<pathelement location="c:\winnt\System32"/>

</path>

<pathconvert targetos="unix" property="wl.path.unix" refid="wl.path">

<map from="${wl.home}" to="${wl.home.unix}"/>

<map from="c:" to=""/>

</pathconvert> will generate the path shown below and store it in the property name d wl.path.unix.

/weblogic/lib/weblogicaux.jar:/weblogic/classes:/weblogic/mssqlserver4/classe s:/WINNT/SYSTEM32

Example 2

Given a FileList defined as:

<filelist id="custom_tasks.jars"

dir="${env.HOME}/ant/lib"

files="njavac.jar,xproperty.jar"/> then:

<pathconvert targetos="unix" property="custom_tasks.jars" refid="custom_tasks.jars">

<map from="${env.HOME}" to="/usr/local"/>

</pathconvert> will convert the list of files to the following Unix path:

/usr/local/ant/lib/njavac.jar:/usr/local/ant/lib/xproperty.jar

Example 3

<fileset dir="${src.dir}" id="src.files">

<include name="**/*.java"/>

</fileset>

<pathconvert pathsep="," property="javafiles" refid="src.files"/>

This example takes the set of files determined by the fileset (all files ending in .java), joins them together separated by commas, and places the resulting list into the property javafiles

. The directory separator is not specified, so it defaults to the appropriate character for the current platform. Such a list could then be used in another task, like javadoc

, that requires a comma separated list of files.

9.49 Property

Description

Sets a property (by name and value), or set of properties (from file or resource) in the project. Properties are case sensitive.

141/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Properties are immutable: whoever sets a property first freezes it for the rest of the build; they are most definately not variable.

There are five ways to set properties:

• By supplying both the name and value attribute.

• By supplying both the name and refid attribute.

• By setting the file attribute with the filename of the property file to load. This property file has the format as defined by the file used in the class java.util.Properties.

• By setting the resource attribute with the resourc e name of the property file to load.

This property file has the format as defined by the file used in the class java.util.Properties.

• By setting the environment attribute with a prefix to use. Properties will be defined for every environment variable by prefixing the supplied name and a period to the name of the variable.

Although combinations of these ways are possible, only one should be used at a time.

Problems might occur with the order in which properties are set, for instance.

The value part of the properties being set, might contain references to other properties.

These references are resolved at the time these properties are set. This also holds for properties loaded from a property file.

A list of predefined properties can be found here .

Parameters

Attribute Description

name value location refid the name of the property to set.

Required

No the value of the property.

Sets the property to the absolute filename of the given file. If the value of this attribute is an absolute path, it is left unchanged (with / and \ characters converted to the current platforms conventions). Otherwise it is taken as a path relative to the project's basedir and expanded.

One of these, when using the name attribute

Reference to an object defined elsewhere. Only yields reasonable results for references to PATH like structures or properties. resource file the resource name of the property file. the filename of the property file . environment the prefix to use when retrieving environment variables. Thus if you specify environment="myenv" you will be able to access OS-specific environment variables via property names "myenv.PATH" or

"myenv.TERM". Note that if you supply a property name with a final "." it will not be doubled. ie environment="myenv." will still allow access of environment variables through "myenv.PATH" and "myenv.TERM". This functionality is currently only implemented on select platforms. Feel free to send patches to increase the number of platforms this functionality is supported on ;).

Note also that properties are case sensitive, even if the environment variables on your operating system are not, e.g. it will be ${env.Path} not ${env.PATH} on Windows 2000.

One of these, when not using the name attribute classpath the classpath to use when looking up a resource. No classpathref the classpath to use when looking up a resource, given as reference to a No

142/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<path> defined elsewhere.. prefix Prefix to apply to properties loaded using file or resource. A "." is appended to the prefix if not specified.

No

Parameters specified as nested elements

classpath

Property's classpath attribute is a PATH like structure and can also be set via a nested classpath element.

Examples

<property name="foo.dist" value="dist"/> sets the property foo.dist to the value "dist".

<property file="foo.properties"/> reads a set of properties from a file called "foo.properties".

<property resource="foo.properties"/> reads a set of properties from a resource called "foo.properties".

Note that you can reference a global properties file for all of your Ant builds using the following:

<property file="${user.home}/.ant-global.properties"/> since the "user.home" property is defined by the Java virtual machine to be your home directory. This technique is more appropriate for Unix than Windows since the notion of a home directory doesn't exist on Windows. On the JVM that I tested, the home directory on

Windows is "C:\". Different JVM implementations may use other values for the home directory on Windows.

<property environment="env"/>

<echo message="Number of Processors = ${env.NUMBER_OF_PROCESSORS}"/>

<echo message="ANT_HOME is set to = ${env.ANT_HOME}"/> reads the system environment variables and stores them in properties, prefixed with "env".

Note that this only works on select operating systems. Two of the values are shown being echoed.

9.50 Record

Description

A recorder is a listener to the current build process that records the output to a file.

Several recorders can exist at the same time. Each recorder is associated with a file. The filename is used as a unique identifier for the recorders. The first call to the recorder task with an unused filename will create a recorder (using the parameters provided) and add it to the listeners of the build. All subsequent calls to the recorder task using this filename will modify that recorders state (recording or not) or other properties (like logging level).

143/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Some technical issues: the file's print stream is flushed for "finished" events (buildFinished, targetFinished and taskFinished), and is closed on a buildFinished event.

Parameters

Attribute Description

name action

The name of the file this logger is associated with.

This tells the logger what to do: should it start recording or stop? The first time that the recorder task is called for this logfile, and if this attribute is not provided, then the default for this attribute is "start". If this attribute is not provided on subsequent calls, then the state remains as previous. [Values =

{start|stop}, Default = no state change]

Required

yes no append Should the recorder append to a file, or create a new one? This is only applicable the first time this task is called for this file. [Values = {yes|no},

Default=yes] no emacsmode Removes [task] banners like Ant's -emacs command line switch if set to true. no, default is false loglevel At what logging level should this recorder instance record to? This is not a once only parameter (like append is) -- you can increase or decrease the logging level as the build process continues. [Values=

{error|warn|info|verbose|debug}, Default = no change] no

Examples

The following build.xml snippet is an example of how to use the recorder to record just the

<javac> task:

...

<compile >

<record name="log.txt" action="start"/>

<javac ...

<record name="log.txt" action="stop"/>

<compile/>

...

The following two calls to <record> set up two recorders: one to file "records-simple.log" at logging level info (the default) and one to file "ISO.log" using logging level of verbose.

...

<record name="records-simple.log"/>

<record name="ISO.log" loglevel="verbose"/>

...

Notes

There is some functionality that I would like to be able to add in the future. They include things like the following:

Attribute Description Required

listener A classname of a build listener to use from this point on instead of the default listener. no includetarget excludetarget

A comma-separated list of targets to automatically record. If this value is

"all", then all targets are recorded. [Default = all] no no includetask excludetask action

A comma-separated list of task to automatically record or not. This could be difficult as it could conflict with the includetarg et/excludetarget. (e.g.: includetarget="compile" exlcudetask="javac", what should happen?) add greater flexibility to the action attribute. Things like close to close the print stream. no no no

Ant Manual 1.5.4 12/9/2003 7:47 PM

9.51 Rename – Deprecated

This task has been deprecated. Use the Move task instead.

Description

Renames a given file.

Parameters

Attribute Description Required

src file to rename. Yes dest new name of the file. Yes replace Enable replacing of existing file (default: on). No

Examples

<rename src="foo.jar" dest="${name}-${version}.jar"/>

Renames the file foo.jar to ${name}-${version}.jar (assuming name and version being predefined properties). If a file named ${name}-${version}.jar already exists, it will be removed prior to renaming foo.jar.

9.52 Replace

Description

Replace is a directory based task for replacing the occurrence of a given string with another string in selected file.

If you want to replace a text that crosses line boundaries, you must use a nested

<replacetoken>

element.

The output file is only written if it differs from the existing file. This prevents spurious rebuilds based on unchanged files which have been regenerated by this task.

Parameters

Attribute

file dir

Description

file for which the token should be replaced.

The base directory to use when replacing a token in multiple files.

Required

Exactly one of the two. encoding token

The encoding of the files upon which replace operates. the token which must be replaced.

No - defaults to default JVM encoding

Yes, unless a neste d replacetoken element or the replacefilterfile attribute is used.

No value summary the new value for the token. When omitted, an empty string ("") is used.

Indicates whether a summary of the replace operation should be produced, detailing how many token occurrences and files were processed

No, by default no summary is produced propertyFile valid property file from which properties specified using nested <replacefilter> elements are drawn.

Yes only if property attribute of

<replacefilter> is used. replacefilterfile valid property file. Each property will be treated as No.

145/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

includes includesfile excludes excludesfile a replacefilter where token is the name of the property and value is the properties value. comma- or space-separated list of patterns of files that must be included. All files are included when omitted. the name of a file. Each line of this file is taken to be an include pattern

No

No comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted.

No the name of a file. Each line of this file is taken to be an exclude pattern

No defaultexcludes indicates whether default excludes should be used or not ("yes"/"no"). Default excludes are used when omitted.

No

Examples

<replace file="${src}/index.html" token="@@@" value="wombat"/> replaces occurrences of the string "@@@" with the string "wombat", in the file

${src}/index.html

.

Parameters specified as nested elements

This task forms an implicit FileSet and supports all attributes of <fileset> as well as the nested <include>, <exclude> and <patternset> elements.

If either the text you want to replace or the replacement text cross line boundaries, you can use nested elements to specify them.

Examples

<replace dir="${src}" value="wombat">

<include name="**/*.html"/>

<replacetoken><![CDATA[multi line token]]></replacetoken>

</replace> replaces occurrences of the string "multi line\ntoken" with the string "wombat", in all HTML files in the directory ${src}.Where \n is the platform specific line separator.

<replace file="${src}/index.html">

<replacetoken><![CDATA[two line token]]></replacetoken>

<replacevalue><![CDATA[two line token]]></replacevalue>

</replace>

9.52.1 replacefilter

In addition to allowing for multiple replacements, optional nested <replacefilter> elements allow replacement values to be extracted from a property file. The name of this file is specified using the <replace> attribute propertyFile.

Attribute Description Required

token The string to search for. Yes

146/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

value The replacement string. property Name of the property whose value is to serve as the replacement value.

Either may be specified, but not both. Both can be omitted, if desired.

If neither value nor property is used, the value provided using the <replace> attribute

value and/or the <replacevalue> element is used. If no value was specified using either of these options, the token is replaced with an empty string.

Examples

<replace

file="configure.sh"

value="defaultvalue"

propertyFile="source/name.properties">

<replacefilter

token="@[email protected]"/>

<replacefilter

token="@[email protected]"

value="value2"/>

<replacefilter

token="@[email protected]"

property="property.key"/>

</replace>

In file configure.sh, replace all instances of "@[email protected]" with "defaultvalue", all instances of "@[email protected]" with "value2", and all instances of "@[email protected]" with the value of the property "property.key", as it appears in property file src/name.properties.

Note: It is possible to use either the token/<replacetoken> and value/<replacevalue> attributes/elements, the nested replacefilter elements, or both in the same operation.

9.53 Rmic

Description

Runs the rmic compiler for a certain class.

Rmic can be run on a single class (as specified with the classname attribute) or a number of classes at once (all classes below base that are neither _Stub nor _Skel classes). If you want to rmic a single class and this class is a class nested into another class, you have to specify the classname in the form Outer$$Inner instead of Outer.Inner.

It is possible to refine the set of files that are being rmiced. This can be done with the

includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the

includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes base

) as well as the nested <include>, <exclude> and <patternset> elements.

147/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

It is possible to use different compilers. This can be selected with the "build.rmic" property or the compiler attribute. There are three choices:

• sun (the standard compiler of the JDK)

• kaffe (the standard compiler of Kaffe )

• weblogic

The miniRMI project contains a compiler implementation for this task as well, please consult miniRMI's documentation to learn how to use it.

No compiler The compiler implementation to use. If this attribute is not set, the value of the build.rmic property, if set, will be used. Otherwise, the default compiler for the current VM will be used. (See the above list of valid compilers.)

Parameters specified as nested elements classpath and extdirs

148/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Rmic's classpath and extdirs attributes are PATH like structure and can also be set via a nested classpath and extdirs elements.

compilerarg

You can specify additional command line arguments for the compiler with nested

<compilerarg> elements. These elements are specified like Command-line Arguments but have an additional attribute that can be used to enable arguments only if a given compiler implementation will be used.

Required Attribute Description

value line file

See Command-line Arguments .

Exactly one of these. path compiler Only pass the specified argument if the chosen compiler implementation matches the value of this attribute. Legal values are the same as those in the above list of valid compilers.)

Examples

<rmic classname="com.xyz.FooBar" base="${build}/classes"/>

No runs the rmic compiler for the class com.xyz.FooBar. The compiled files will be stored in the directory ${build}/classes.

<rmic base="${build}/classes" includes="**/Remote*.class"/> runs the rmic compiler for all classes with .class files below ${build}/classes whose classname starts with Remote. The compiled files will be stored in the directory

${build}/classes

.

9.54 Sequential

Description

Sequential is a container task - it can contain other Ant tasks. The nested tasks are simply executed in sequence. Sequential's primary use is to support the sequential execution of a subset of tasks within the parallel task

The sequential task has no attributes and does not support any nested elements apart from

Ant tasks. Any valid Ant task may be embedded within the sequential task.

Example

<parallel>

<wlrun ... >

<sequential>

<sleep seconds="30"/>

<junit ... >

<wlstop/>

</sequential>

</parallel>

This example shows how the sequential task is used to execute three tasks in sequence, while another task is being executed in a separate thread.

149/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

9.55 SignJar

Description

Signs jar or zip files with the javasign command line tool. The tool detailed dependency checking: files are only signed if they are not signed. The signjar attribute can point to the file to generate; if this file exists then its modification date is used as a cue as to whether to resign any JAR file.

Note: Requires Java 1.2 or later.

Parameters

Attribute Description

Required

Yes, unless nested filesets have been used. alias the alias to sign under storepass password for keystore integrity. keystore keystore location storetype keystore type keypass password for private key (if different) sigfile name of .SF/.DSA file signedjar name of signed JAR file

Yes.

Yes.

No

No

No

No

No verbose (true | false) verbose output when signing internalsf (true | false) include the .SF file inside the signature block sectionsonly (true | false) don't compute hash of entire manifest lazy flag to control whether the presence of a signature file means a

JAR is signed

No; default false

No; default false

No; default false

No; default false maxmemory Specifies the maximum memory the jarsigner VM will use.

Specified in the style of standard java memory specs (e.g. 128m

= 128 MBytes)

No

Parameters as nested elements

Attribute Description Required

fileset fileset of JAR files to sign. Will be ignored if the jar attribute of the task has been set.

No

Examples

<signjar jar="${dist}/lib/ant.jar" alias="apache-group" storepass="secret"/> signs the ant.jar with alias "apache-group" accessing the keystore and private key via

"secret" password.

9.56 Sleep

Description

A task for sleeping a short period of time, useful when a build or deployment process requires an interval between tasks.

Parameters

Attribute Description Required

hours hours to to add to the sleep time No

150/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

minutes minutes to add to the sleep time No seconds seconds to add to the sleep time milliseconds milliseconds to add to the sleep time

No

No failonerror flag controlling whether to break the build on an error. No

The sleep time is the sum of specified values, hours, minutes seconds and milliseconds. A negative value can be supplied to any of them provided the total sleep time is positive

Note that sleep times are always hints to be interpred by the OS how it feels - small times may either be ignored or rounded up to a minimum timeslice. Note also that the system clocks often have a fairly low granularity too, which complicates measuring how long a sleep actually took.

Examples

<sleep milliseconds="10"/>

Sleep for about 10 mS.

<sleep seconds="2"/>

Sleep for about 2 seconds.

<sleep hours="1" minutes="-59" seconds="-58"/>

Sleep for one hour less 59:58, or two seconds again

<sleep/>

Sleep for no time at all. This may yield the CPU time to another thread or process.

9.57 Sql

Description

Executes a series of SQL statements via JDBC to a database. Statements can either be read in from a text file using the src attribute or from between the enclosing SQL tags.

Multiple statements can be provided, separated by semicolons (or the defined delimiter).

Individual lines within the statements can be commented using either --, // or REM at the start of the line.

The autocommit attribute specifies whether auto-commit should be turned on or off whilst executing the statements. If auto-commit is turned on each statement will be executed and committed. If it is turned off the statements will all be executed as one transaction.

The onerror attribute specifies how to proceed when an error occurs during the execution of one of the statements. The possible values are: continue execution, only show the error;

stop execution and commit transaction; and abort execution and transaction and fail task.

Parameters

Attribute Description

driver Class name of the jdbc driver

No, default "abort"

No (no restriction)

No (no restriction)

No (default=true)

Parameters specified as nested elements

transaction

Use nested <transaction> elements to specify multiple blocks of commands to the executed executed in the same connection but different transactions. This is particularly useful when there are multiple files to execute on the same schema.

Attribute Description Required

src File containing SQL statements Yes, unless statements enclosed within tags

fileset

You can specify multiple source files via nested fileset elements. Each file of the fileset will be run in a transaction of its own, the order by which the files of a single fileset will be executed is not defined.

classpath

Sql's classpath attribute is a PATH like structure and can also be set via a nested classpath element. It is used to load the JDBC classes.

Examples

<sql

driver="org.database.jdbcDriver"

url="jdbc:database-url"

userid="sa"

password="pass"

src="data.sql"

/>

152/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Connects to the database given in url as the sa user using the org.database.jdbcDriver and executes the SQL statements contained within the file data.sql

<sql

driver="org.database.jdbcDriver"

url="jdbc:database-url"

userid="sa"

password="pass"

> insert into table some_table values(1,2,3,4); truncate table some_other_table;

</sql>

Connects to the database given in url as the sa user using the org.database.jdbcDriver and executes the two SQL statements inserting data into some_table and truncating some_other_table

Note that you may want to enclose your statements in <![CDATA[ ... ]]> sections so you don't need to escape <, > & or other special characters. For example:

<sql

driver="org.database.jdbcDriver"

url="jdbc:database-url"

userid="sa"

password="pass"

><![CDATA[ update some_table set column1 = column1 + 1 where column2 < 42;

]]></sql>

The following connects to the database given in url as the sa user using the org.database.jdbcDriver and executes the SQL statements contained within the files data1.sql, data2.sql and data3.sql and then executes the truncate operation on

some_other_table.

<sql

driver="org.database.jdbcDriver"

url="jdbc:database-url"

userid="sa"

password="pass" >

<transaction src="data1.sql"/>

<transaction src="data2.sql"/>

<transaction src="data3.sql"/>

<transaction>

truncate table some_other_table;

</transaction>

</sql>

153/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

The following example does the same as (and may execute additional SQL files if there are more files matching the pattern data*.sql) but doesn't guarantee that data1.sql will be run before data2.sql.

<sql

driver="org.database.jdbcDriver"

url="jdbc:database-url"

userid="sa"

password="pass">

<fileset dir=".">

<include name="data*.sql"/>

</fileset>

<transaction>

truncate table some_other_table;

</transaction>

</sql>

The following connects to the database given in url as the sa user using the org.database.jdbcDriver and executes the SQL statements contained within the file data.sql, with output piped to outputfile.txt, searching /some/jdbc.jar as well as the system classpath for the driver class.

<sql

driver="org.database.jdbcDriver"

url="jdbc:database-url"

userid="sa"

password="pass"

src="data.sql"

print="yes"

output="outputfile.txt"

>

<classpath>

<pathelement location="/some/jdbc.jar"/>

</classpath>

</sql>

The following will only execute if the RDBMS is "oracle" and the version starts with "8.1."

<sql

driver="org.database.jdbcDriver"

url="jdbc:database-url"

userid="sa"

password="pass"

src="data.sql"

rdbms="oracle"

version="8.1."

> insert into table some_table values(1,2,3,4); truncate table some_other_table;

</sql>

9.58 Style / Xslt

Description

Process a set of documents via XSLT.

This is useful for building views of XML based documentation, or for generating code.

Note: This task depends on external libraries not included in the Ant distribution. See

Library Dependencies for more information.

It is possible to refine the set of files that are being processed. This can be done with the

includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the

includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes basedir

) as well as the nested <include>, <exclude> and <patternset> elements.

This task supports the use of a nested <param> element which is used to pass values to an

<xsl:param> declaration.

This task supports the use of a nested xmlcatalog element which is used to perform Entity and URI resolution

<style> and <xslt> refer to the same Ant task and can be used interchangeably.

If you want to use Xalan-J 1 or XSL:P, you also need Ant's optional.jar

9.59 Tar

Description

Creates a tar archive.

The basedir attribute is the reference directory from where to tar.

This task is a directory based task and, as such, forms an implicit Fileset . This defines which files, relative to the basedir, will be included in the archive. The tar task supports all the attributes of Fileset to refine the set of files to be included in the implicit fileset.

157/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

In addition to the implicit fileset, the tar task supports nested filesets. These filesets are extended to allow control over the access mode, username and groupname to be applied to the tar entries. This is useful, for example, when preparing archives for Unix systems where some files need to have execute permission.

Early versions of tar did not support path lengths greater than 100 characters. Modern versions of tar do so, but in incompatible ways. The behaviour of the tar task when it encounters such paths is controlled by the longfile attribute. If the longfile attribute is set to fail

, any long paths will cause the tar task to fail. If the longfile attribute is set to truncate

, any long paths will be truncated to the 100 character maximum length prior to adding to the archive. If the value of the longfile attribute is set to omit then files containing long paths will be omitted from the archive. Either option ensures that the archive can be untarred by any compliant version of tar. If the loss of path or file information is not acceptable, and it rarely is, longfile may be set to the value gnu. The tar task will then produce a GNU tar file which can have arbitrary length paths. Note however, that the resulting archive will only be able to be untarred with GNU tar. The default for the longfile attribute is warn which behaves just like the gnu option except that it produces a warning for each file path encountered that does not match the limit.

This task can perform compression by setting the compression attribute to "gzip" or "bzip2".

Parameters

Attribute

destfile basedir longfile includes includesfile excludes

Description

the tar-file to create.

Required

Yes the directory from which to tar the files.

Determines how long files (>100 chars) are to be handled. Allowable values are "truncate", "fail", "warn", "omit" and "gnu". Default is "warn".

No comma- or space-separated list of patterns of files that must be included.

All files are included when omitted. the name of a file. Each line of this file is taken to be an include pattern

No

No

No comma- or space-separated list of patterns of files that must be excluded.

No files (except default excludes) are excluded when omitted.

No excludesfile the name of a file. Each line of this file is taken to be an exclude pattern defaultexcludes indicates whether default excludes should be used or not ("yes"/"no").

Default excludes a re used when omitted.

No

No compression compression method. Allowable values are "none", "gzip" and "bzip2".

Default is "none".

No

Nested Elements

The tar task supports nested tarfileset elements. These are extended Filesets which, in addition to the standard fileset elements, support three additional attributes

Attribute Description Required

mode No username group prefix

A 3 digit octal string, specify the user, group and other modes in the standard Unix fashion

The username for the tar entry. This is not the same as the UID, which is not currently set by the tar task.

The groupname for the tar entry. This is not the same as the GID, which is not currently set by the tar task.

If the prefix attribute is set, all files in the fileset are prefixed with that path in the archive.

No

No

No

158/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

fullpath If the fullpath attribute is set, the file in the fileset is written with that path in the archive. The prefix attribute, if specified, is ignored. It is an error to have more than one file specified in such a fileset. preserveLeadingSlashes Indicates whether leading `/'s should be preserved in the file names. Default is false.

Examples

<tar tarfile="${dist}/manual.tar" basedir="htdocs/manual"/>

<gzip zipfile="${dist}/manual.tar.gz" src="${dist}/manual.tar"/>

No

No tars all files in the htdocs/manual directory into a file called manual.tar in the ${dist} directory, then applies the gzip task to compress it.

<tar destfile="${dist}/manual.tar"

basedir="htdocs/manual"

excludes="mydocs/**, **/todo.html"

/> tars all files in the htdocs/manual directory into a file called manual.tar in the ${dist} directory. Files in the directory mydocs, or files with the name todo.html are excluded.

<tar destfile="${basedir}/docs.tar">

<tarfileset dir="${dir.src}/docs"

fullpath="/usr/doc/ant/README"

preserveLeadingSlashes="true">

<include name="readme.txt"/>

</tarfileset>

<tarfileset dir="${dir.src}/docs"

prefix="/usr/doc/ant"

preserveLeadingSlashes="true">

<include name="*.html"/>

</tarfileset>

</tar>

Writes the file docs/readme.txt as /usr/doc/ant/README into the archive. All *.html files in the docs directory are prefixed by /usr/doc/ant, so for example docs/index.html is written as /usr/doc/ant/index.html to the archive.

<tar longfile="gnu"

destfile="${dist.base}/${dist.name}-src.tar" >

<tarfileset dir="${dist.name}/.." mode="755" username="ant" group="ant">

<include name="${dist.name}/bootstrap.sh"/>

<include name="${dist.name}/build.sh"/>

</tarfileset>

<tarfileset dir="${dist.name}/.." username="ant" group="ant">

<include name="${dist.name}/**"/>

<exclude name="${dist.name}/bootstrap.sh"/>

<exclude name="${dist.name}/build.sh"/>

</tarfileset>

</tar>

159/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

This example shows building a tar which uses the GNU extensions for long paths and where some files need to be marked as executable (mode 755) and the rest are use the default mode (read-write by owner). The first fileset selects just the executable files. The second fileset must exclude the executable files and include all others.

Note: The tar task does not ensure that a file is only selected by one fileset. If the same file is selected by mo re than one fileset, it will be included in the tar file twice, with the same path.

Note: The patterns in the include and exclude elements are considered to be relative to the corresponding dir attribute as with all other filesets. In the example above, ${dist.name} is not an absolute path, but a simple name of a directory, so ${dist.name} is a valid path relative to ${dist.name}/...

9.60 Taskdef

Description

Adds a task definition to the current project, such that this new task can be used in the current project. Two attributes are needed, the name that identifies this task uniquely, and the full name of the class (including the packages) that implements this task.

You can also define a group of tasks at once using the file or resource attributes. These attributes point to files in the format of Java property files. Each line defines a single task in the format: taskname=fully.qualified.java.classname

Taskdef should be used to add your own tasks to the system. See also " Writing your own task ".

Parameters

Attribute Description

name the name of the task classname the full class name implementing the task file Name of the property file to load taskname/classname pairs from. resource Name of the property resource to load taskname/classname pairs from. classpath the classpath to use when looking up classname or resource. No classpathref Reference to a classpath to use when looking up classname or resource.

No loaderRef the name of the loader that is used to load the class, constructed from the specified classpath. Use this to allow multiple tasks/types to be loaded with the same loader, so they can call each other. ( introduced in ant1.5 )

No

Parameters specified as nested elements classpath

Required

Yes, unless file or resource have been specified.

Yes, unless file or resource have been specified.

No

No

160/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Taskdef's classpath attribute is a PATH like structure and can also be set via a nested classpath element.

Examples

<taskdef name="myjavadoc" classname="com.mydomain.JavadocTask"/> makes a task called myjavadoc available to Ant. The class com.mydomain.JavadocTask implements the task.

9.61 Tempfile

Description

This task sets a property to the name of a temporary file. Unlike the Java1.2 method to create a temporary file, this task does work with Java1.1. It does not actually create the temporary file, but it does guarantee that the file did not exist when the task was executed.

Parameters

Attribute Description Required

No destdir The directory the temporary file should be located in. If not set, the current directory is used. prefix A prefix for the temporary file name. property The name of the property to set with the value of the temporary file name. suffix A suffix for the temporary file name.

Examples

<tempfile property="temp.file"/>

No

Yes

No will set temp.file to the name of a new temporary file.

<tempfile property="temp.file" suffix=".xml"/> will set temp.file to the name of a new temporary file with a suffix of .xml.

<tempfile property="temp.file" destdir="build"/> will set temp.file to the name of a new temporary file located in the build sub-directory.

9.62 Touch

Description

Changes the modification time of a file and possibly creates it at the same time. In addition to working with a single file, this Task can also work a Fileset (which also includes directories).

For JDK 1.1 only the creation of new files with a modification time of now works, all other cases will emit a warning.

Parameters

Attribute Description

file the name of the file

Required

unless a nested fileset element

161/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

millis specifies the new modification time o f the file in milliseconds since midnight Jan 1 1970 datetime specifies the new modification time of the file in the format MM/DD/YYYY HH:MM AM_or_PM. has been specified.

No

No

If both millis and datetime are omitted the current time is assumed.

Examples

<touch file="myfile"/> creates myfile if it doesn't exist and changes the modification time to the current time.

<touch file="myfile" datetime="06/28/2000 2:02 pm"/> creates myfile if it doesn't exist and changes the modification time to Jun, 28 2000 2:02 pm (14:02 for those used to 24 hour times).

<touch datetime="09/10/1974 4:30 pm">

<fileset dir="src_dir"/>

</touch> changes the modification time to Oct, 09 1974 4:30 pm of all files and directories found in src_dir

.

9.63 Tstamp

Description

Sets the DSTAMP, TSTAMP, and TODAY properties in the current project. By default, the

DSTAMP property is in the format "yyyyMMdd", TSTAMP is in the format "hhmm", and

TODAY is in the format "MMMM dd yyyy". Use the nested <format> element to specify a different format.

These properties can be used in the build-file, for instance, to create time -stamped filenames, or used to replace placeholder tags inside documents to indicate, for example, the release date. The best place for this task is probably in an initialization target.

Parameters

Attribute Description

prefix

Required

Prefix used for all properties set. The default is no prefix. No

Nested Elements

The Tstamp task supports a <format> nested element that allows a property to be set to the current date and time in a given format. The date/time patterns are as defined in the

Java SimpleDateFormat class. The format element also allows offsets to be applied to the time to generate different time values.

Attribute Description Required

property The property to receive the date/time string in the given pattern. pattern The date/time pattern to be used. The values are as defined by the Java

SimpleDateFormat class.

Yes

Yes

162/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

timezone The time zone to use for displaying time. The values are as defined by the Java

TimeZone class. offset The numeric offset to the current time unit The unit of the offset to be applied to the current time. Valid Values are : millisecond second minute hour day week month year locale The locale used to create date/time string. The general form is "language, country, variant" but either variant or variant and country may be omitted. For more information please refer to documentation for the Locale class.

Examples

<tstamp/>

No

No

No

No sets the standard DSTAMP, TSTAMP, and TODAY properties according to the default formats.

<tstamp>

<format property="TODAY_UK" pattern="d-MMMM-yyyy" locale="en"/>

</tstamp> sets the standard properties as well as the property TODAY_UK with the date/time pattern

"d-MMMM-yyyy" using English locale (eg. 21-May-2001).

<tstamp>

<format property="touch.time" pattern="MM/dd/yyyy hh:mm aa"

offset="-5" unit="hour"/>

</tstamp>

Creates a timestamp, in the property touch.time, 5 hours before the current time. The format in this example is suitable for use with the <touch> task. The standard properties are set also.

<tstamp prefix="start"/>

Sets three properties with the standard formats, prefixed with "start.": start.DSTAMP, start.TSTAMP

, and start.TODAY.

9.64 Typedef

Description

Adds a data type definition to the current project, such that this new type can be used in the current project. Two attributes are needed, the name that identifies this data type uniquely, and the full name of the class (including the packages) that implements this type.

You can also define a group of data types at once using the file or resource attributes. These attributes point to files in the format of Java property files. Each line defines a single data type in the format:

163/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

typename=fully.qualified.java.classname

Typedef should be used to add your own types to the system. Data types are things like paths or filesets that can be defined at the project level and referenced via their ID attribute.

Custom data types usually need custom tasks to put them to good use.

Parameters

Attribute Description

name the name of the data type

Required

Yes, unless file or resource have been specified. classname the full class name implementing the data type Yes, unless file or resource have been specified.

No file Name of the property file to load typename/classname pairs from. resource Name of the property resource to load typename/classname pairs from. classpath the classpath to use when looking up classname.

No

No loaderRef the name of the loader that is used to load the class, constructed from the specified classpath.

Use this to allow multiple tasks/types to be loaded with the same loader, so they can call each other.

(introduced in ant1.5 )

No

Parameters specified as nested elements classpath

Typedef's classpath attribute is a PATH like structure and can also be set via a nested classpath element.

Examples

<typedef name="urlset" classname="com.mydomain.URLSet"/> makes a data type called urlset available to Ant. The class com.mydomain.URLSet implements this type.

9.65 Unjar/Untar/Unwar/Unzip

Description

Unzips a zip-, war-, tar- or jarfile.

For JDK 1.1 "last modified time" field is set to current time instead of being carried from the archive file.

PatternSet s are used to select files to extract from the archive. If no patternset is used, all files are extracted.

FileSet s may be used used to select archived files to perform unarchival upon.

File permissions will not be restored on extracted files.

The untar task recognizes the long pathname entries used by GNU tar.

164/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Parameters

Attribute Description

src archive file to expand. dest directory where to store the expanded files. overwrite Overwrite files, even if they are newer than the corresponding entries in the archive (true or false, default is true). compression compression method for untar. Allowable values are "none", "gzip" and "bzip2". Default is "none".

Examples

Required

Yes, if filesets are not used.

Yes

No

No

<unzip src="${tomcat_src}/tools-src.zip" dest="${tools.home}"/>

<gunzip src="tools.tar.gz"/>

<untar src="tools.tar" dest="${tools.home}"/>

<unzip src="${tomcat_src}/tools-src.zip"

dest="${tools.home}">

<patternset>

<include name="**/*.java"/>

<exclude name="**/Test*.java"/>

</patternset>

</unzip>

<unzip dest="${tools.home}">

<patternset>

<include name="**/*.java"/>

<exclude name="**/Test*.java"/>

</patternset>

<fileset dir=".">

<include name="**/*.zip"/>

<exclude name="**/tmp*.zip"/>

</fileset>

</unzip>

9.66 Uptodate

Description

Sets a property if a target file or set of target files is more up-to-date than a source file or set of source files. A single source file is specified using the srcfile attribute. A set of source files is specified using the nested <srcfiles> elements. These are FileSet s, whereas multiple target files are specified using a nested <mapper> element.

By default, the value of the property is set to true if the timestamp of the target file(s) is more recent than the timestamp of the corresponding source file(s). You can set the value to something other than the default by specifying the value attribute.

If a <srcfiles> element is used, without also specifying a <mapper> element, the default behavior is to use a merge mapper , with the to attribute set to the value of the targetfile attribute.

Normally, this task is used to set properties that are useful to avoid target execution depending on the relative age of the specified files.

165/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Parameters

Attribute Description

property The name of the property to set.

Required

Yes value srcfile

The value to set the property to. No; defaults to true.

The file to check against the target file(s). Yes, unless a nested <srcfiles> element is present. targetfile The file for which we want to determine the status.

Yes, unless a nested <mapper> element is present.

Parameters specified as nested elements

srcfiles

The nested <srcfiles> element allows you to specify a set of files to check against the target file(s).

Note: You can specify either the srcfile attribute or nested <srcfiles> elements, but not both.

mapper

The nested <mapper> element allows you to specify a set of target files to check for being up-to-date with respect to a set of source files.

Examples

<uptodate property="xmlBuild.notRequired" targetfile="${deploy}\xmlClasses.jar" >

<srcfiles dir= "${src}/xml" includes="**/*.dtd"/>

</uptodate> sets the property xmlBuild.notRequired to true if the ${deploy}/xmlClasses.jar file is more up-to-date than any of the DTD files in the ${src}/xml directory.

This can be written as:

<uptodate property="xmlBuild.notRequired">

<srcfiles dir= "${src}/xml" includes="**/*.dtd"/>

<mapper type="merge" to="${deploy}\xmlClasses.jar"/>

</uptodate> as well. The xmlBuild.notRequired property can then be used in a <target> tag's unless attribute to conditionally run that target. For example, running the following target:

<target name="xmlBuild" depends="chkXmlBuild" unless="xmlBuild.notRequired">

...

</target> will first run the chkXmlBuild target, which contains the <uptodate> task that determines whether xmlBuild.notRequired gets set. The property named in the unless attribute is then checked for being set/not set. If it did get set (ie., the jar file is up-to-date), then the xmlBuild

target won't be run.

The following example shows a single source file being checked against a single target file:

<uptodate property="isUpToDate"

166/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

srcfile="/usr/local/bin/testit"

targetfile="${build}/.flagfile"/> sets the property isUpToDate to true if /usr/local/bin/testit is newer than

${build}/.flagfile

.

9.67 Waitfor

Description

Blocks execution until a set of specified conditions become true. This is intended to be used with the parallel task to synchronize a set of processes.

The conditions to wait for are defined in nested elements , if multiple conditions are specified, then the task will wait until all conditions are true..

If both maxwait and maxwaitunit are not specified, the maxwait is 3 minutes (180000 milliseconds).

If the timeoutproperty attribute has been set, a property of that name will be created if the condition didn't come true within the specified time.

Parameters

Attribute

maxwait

Description

The maximum amount of time to wait for all the required conditions to become true before failing the task.

Defaults to 180000 maxwaitunits.

Required

No maxwaitunit checkevery

The unit of time that must be used to interpret the value of the maxwait attribute. Defaults to millisecond. Valid Values are :

• millisecond

• second

• minute

• hour

• day

• week

The amount of time to wait between each test of the conditions.

Defaults to 500 checkeveryunits.

No

No checkeveryunit The unit of time that must be used to interpret the value of the checkevery No attribute. Defaults to millisecond. Valid Values are :

• millisecond

• second

• minute

• hour

• day

• week timeoutproperty the name of the property to set if maxwait has been exceeded. No

Nested Elements

The available conditions that satisfy the <waitfor> task are the same as those for the

<condition> task. See here for the full list.

Examples

167/305

Ant Manual 1.5.4

<waitfor maxwait="30" maxwaitunit="second">

<available file="errors.log"/>

</waitfor>

12/9/2003 7:47 PM

waits up to 30 seconds for a file called errors.log to appear.

<waitfor maxwait="3" maxwaitunit="minute" checkevery="500">

<http url="http://localhost/myapp/index.html"/>

</waitfor> waits up to 3 minutes (and checks every 500 milliseconds) for a web server on localhost to serve up the specified URL.

<waitfor maxwait="10" maxwait="second">

<and>

<socket server="dbserver" port="1521"/>

<http url="http://webserver/mypage.html"/>

</and>

</waitfor> waits up to 10 seconds for a server on the dbserver machine to begin listening on port 1521 and for the http://webserver/mypage.html web page to become available.

9.68 War

Description

An extension of the Jar task with special treatment for files that should end up in the WEB-

INF/lib, WEB-INF/classes or WEB-INF directories of the Web Application Archive.

(The War task is a shortcut for specifying the particular layout of a WAR file. The same thing can be accomplished by using the prefix and fullpath attributes of zipfilesets in a Zip or Jar task.)

The extended zipfileset element from the zip task (with attributes prefix, fullpath, and src) is available in the War task.

Parameters

Attribute

destfile warfile webxml basedir compress encoding filesonly

Description

the WAR file to create.

Deprecated name of the file to create -use destfile instead.

The deployment descriptor to use (WEB-INF/web.xml). the directory from which to jar the files.

Not only store data but also compress them, defaults to true

The character encoding to u se for filenames inside the archive.

Defaults to UTF8.

It is not recommended to change this value as the created archive will most likely be unreadable for Java otherwise.

Store only file entries, defaults to false No

The nested lib element specifies a FileSet . All files included in this fileset will end up in the

WEB-INF/lib directory of the war file.

classes

The nested classes element specifies a FileSet . All files included in this fileset will end up in the WEB-INF/classes directory of the war file.

webinf

The nested webinf element specifies a FileSet . All files included in this fileset will end up in the WEB-INF directory of the war file. If this fileset includes a file named web.xml, the file is ignored and you will get a warning.

metainf

The nested metainf element specifies a FileSet . All files included in this fileset will end up in the META-INF directory of the war file. If this fileset includes a file named MANIFEST.MF, the file is ignored and you will get a warning.

Examples

Assume the following structure in the project's base directory: thirdparty/libs/jdbc1.jar thirdparty/libs/jdbc2.jar build/main/com/myco/myapp/Servlet.class src/metadata/myapp.xml src/html/myapp/index.html src/jsp/myapp/front.jsp src/graphics/images/gifs/small/logo.gif src/graphics/images/gifs/large/logo.gif then the war file myapp.war created with

9.70 Xslt / Style

See Style.

9.71 Zip

Description

Creates a zipfile.

The basedir attribute is the reference directory from where to zip.

Note that file permissions will not be stored in the resulting zipfile.

It is possible to refine the set of files that are being zipped. This can be done with the

includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the

includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes basedir

) as well as the nested <include>, <exclude> and <patternset> elements.

Or, you may place within it nested file sets, or references to file sets. In this case basedir is optional; the implicit file set is only used if basedir is set. You may use any mixture of the implicit file set (with basedir set, and optional attributes like includes and optional subelements like <include>); explicit nested <fileset> elements so long as at least one fileset total is specified. The ZIP file will only reflect the relative paths of files within each fileset. The Zip task and its derivatives know a special form of a fileset named zipfileset that has additional attributes (described below).

The Zip task also supports the merging of multiple zip files into the zip file. This is possible through either the src attribute of any nested filesets or by using the special nested fileset

zipgroupfileset.

171/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

The update parameter controls what happens if the ZIP file already exists. When set to yes, the ZIP file is updated with the files specified. (New files are added; old files are replaced with the new versions.) When set to no (the default) the ZIP file is overwritten. Please note that ZIP files store file modification times with a granularity of two seconds. If a file is less than two seconds newer than the entry in the archive, Ant will not consider it newer.

The whenempty parameter controls what happens when no files match. If skip (the default), the ZIP is not created and a warning is issued. If fail, the ZIP is not created and the build is halted with an error. If create, an empty ZIP file (explicitly zero entries) is created, which should be recognized as such by compliant ZIP manipulation tools.

This task will now use the platform's default character encoding for filenames - this is consistent with the command line ZIP tools, but causes problems if you try to open them from within Java and your filenames contain non US-ASCII characters. Use the encoding attribute and set it to UTF8 to create zip files that can safely be read by Java.

Starting with Ant 1.5.2, <zip> can store Unix permissions inside the archive (see description of the filemode and dirmode attributes for <zipfileset> ). Unfortunately there is no portable way to st ore these permissions. Ant uses the algorithm used by Info-Zip's implementation of the zip and unzip commands - these are the default versions of zip and unzip for many Unix and Unix-like systems.

Parameters

Attribute

destfile zipfile basedir compress encoding

Description

the zip-file to create. the deprecated old name of destfile. the directory from which to zip the files.

Not only store data but also compress them, defaults to true

No files (except default excludes) are excluded when omitted.

No comma- or space-separated list of patterns of files that must be included.

No

All files are included when omitted. the name of a file. Each line of this file is taken to be an include pattern No

No excludesfile the name of a file. Each line of this file is taken to be an exclude pattern No defaultexcludes indicates whether default excludes should be used or not ("yes"/"no"). No

Default excludes are used when omitted. update No whenempty indicates whether to update or overwrite the destination file if it already exists. Default is "false". behavior when no files match. Valid values are "fail", "skip", and

"create". Default is "skip".

Parameters specified as nested elements fileset

The zip task supports any number of nested <fileset> elements to specify the files to be included in the archive.

172/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

zipfileset

A <zipfileset> is a special form of a <fileset> that adds some extra functionality. It supports all attributes of <fileset> in addition to those listed below.

Parameters

Attribute Description Required

prefix all files in the fileset are prefixed with that path in the archive. fullpath the file described by the fileset is placed at that exact location in the archive. src may be used in place of the dir attribute to specify a zip file whose contents will be extracted and included in the archive.

No

No

No filemode A 3 digit octal string, specify the user, group and other modes in the standard

Unix fashion. Only applies to plain files. Default is 644. since Ant 1.5.2.

No dirmode A 3 digit octal string, specify the user, group and other modes in the standard

Unix fashion. Only applies to directories. Default is 755. since Ant 1.5.2.

No

The fullpath attribute can only be set for filesets that represent a single file. The prefix and fullpath attributes cannot both be set on the same fileset.

When using the src attribute, include and exclude patterns may be used to specify a subset of the zip file for inclusion in the archive as with the dir attribute.

zipgroupfileset

A <zipgroupfileset> allows for multiple zip files to be merged into the archive. Each file found in this fileset is added to the archive the same way that zipfileset src files are added.

Examples

<zip destfile="${dist}/manual.zip"

basedir="htdocs/manual"

/> zips all files in the htdocs/manual directory into a file called manual.zip in the ${dist} directory.

<zip destfile="${dist}/manual.zip"

basedir="htdocs/manual"

update="true"

/> zips all files in the htdocs/manual directory into a file called manual.zip in the ${dist} directory. If manual.zip doesn't exist, it is created; otherwise it is updated with the new/changed files.

<zip destfile="${dist}/manual.zip"

basedir="htdocs/manual"

excludes="mydocs/**, **/todo.html"

/> zips all files in the htdocs/manual directory. Files in the directory mydocs, or files with the name todo.html are excluded.

<zip destfile="${dist}/manual.zip"

basedir="htdocs/manual"

includes="api/**/*.html"

excludes="**/todo.html"

173/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

/> zips all files in the htdocs/manual directory. Only html files under the directory api are zipped, and files with the name todo.html are excluded.

<zip destfile="${dist}/manual.zip">

<fileset dir="htdocs/manual"/>

<fileset dir="." includes="ChangeLog.txt"/>

</zip> zips all files in the htdocs/manual directory, and also adds the file ChangeLog.txt in the current directory. ChangeLog.txt will be added to the top of the ZIP file, just as if it had been located at htdocs/manual/ChangeLog.txt.

<zip destfile="${dist}/manual.zip">

<zipfileset dir="htdocs/manual" prefix="docs/user-guide"/>

<zipfileset dir="." includes="ChangeLog27.txt" fullpath="docs/ChangeLog.txt"/>

<zipfileset src="examples.zip" includes="**/*.html" prefix="docs/examples"/>

</zip> zips all files in the htdocs/manual directory into the docs/user-guide directory in the archive, adds the file ChangeLog27.txt in the current directory as docs/ChangeLog.txt, and includes all the html files in examples.zip under docs/examples. The archive might end up containing the files:

docs/user-guide/html/index.html

docs/ChangeLog.txt

docs/examples/index.html

The code

<zip destfile="${dist}/manual.zip">

<zipfileset dir="htdocs/manual" prefix="docs/user-guide"/>

<zipgroupfileset dir="." includes="examples*.zip"/>

</zip> zips all files in the htdocs/manual directory into the docs/user-guide directory in the archive and includes all the files in any file that maches examples*.zip, such as all files within examples1.zip or examples_for_brian.zip.

10 Optional Tasks

10.1 .NET tasks

10.1.1 <CSC>

This task compiles CSharp source into executables or modules. This task compiles CSharp source into executables or modules. The task will only work on win2K/XP or other platforms with csc.exe or an equivalent. CSC must be on the execute path.

All parameters are optional: <csc/> should suffice to produce a debug build of all *.cs files.

References to external files do require explicit enumeration, so are one of the first attributes to consider adding.

The task is a directory based task, so attributes like includes="**/*.cs" and

excludes="broken.cs" can be used to control the files pulled in. By default, all *.cs files from the project folder down are included in the command. When this happens the destFile if not specified- is taken as the first file in the list, which may be somewhat hard to control.

Specifying the output file with 'destfile' seems prudent.

Also, dependency checking only works if destfile is set.

Attribute

10.1.2 <ilasm>

Task to assemble .net 'Intermediate Language' files. The task will only work on windows until other platforms support csc.exe or an equivalent. ilasm.exe must be on the execute path too.

All parameters are optional: <il/> should suffice to produce a debug build of all *.il files.

The option set is roughly compatible with the CSharp class; even though the command line options are only vaguely equivalent. [The low level commands take things like /OUT=file, csc wants /out:file ... /verbose is used some places; /quiet here in ildasm... etc.] It would be nice if someone made all the command line tools consistent (and not as brittle as the java cmdline tools)

The task is a directory based task, so attributes like includes="*.il" and

excludes="broken.il" can be used to control the files pulled in. Each file is built on its own, producing an appropriately named output file unless manually specified with outfile

10.1.3 <WsdlToDotnet>

Why add a wrapper to the MS WSDL tool? So that you can verify that your web services, be they written with Axis or anyone else's SOAP toolkit, work with .NET clients.

This task is dependency aware when using a file as a source and destination; so if you

<get> the file (with usetimestamp="true") then you only rebuild stuff when the WSDL file is changed. Of course, if the server generates a new timestamp every time you ask for the

WSDL, this is not enough...use the <filesmatch> <condition> to to byte for byte comparison against a cached WSDL file then make the target conditional on that test failing.

Attribute Description

destFile name of file to generate. Required srcFile name of WSDL file to use. Required if url is not set url server url to retrive WSDL from. required if srcFile is unset generate server stubs, not client proxy code. optional; default false namespace namespace to place the source in. optional; defa ult "" language language; one of "CS", "JS", or "VB" optional; failOnError Should failure halt the build?

10.1.4 Change Log

Version 0.5

This revision goes along with NET 1.0 (SP1)

1. CSC: added filealign

2. CSC: added reference to office.dll

3. CSC: dependency checking! only if destFile is set!

4. WsdlToDotnet written

Version 0.4

This is the beta-2 revision of the tasks.

1. ILASM: pulled the owner attribute, added keyfile for giving binaries a strong name (MD5 hash of the checksum)

2. CSC: added win32res , noConfig, utf8output, fullpaths

Version 0.3

The changes here reflect Beta-1 of the dotnet SDK and experience of use in more complex projects. This build does not work with the older SDK, primarily because the automatic reference feature references libraries only found in the new SDK version.

External changes

• Recursive inclusion of .cs and .il files

• Documentation enhanced, includes examples and details of all parameters

The csc task automatically includes the common dotnet assemblies, so there is no need to remember to refer to 'System.dll', 'System.Web.Services', etc. This feature can be disabled by setting the 'includeDefaultReferences' flag to false.

References can also be referred to using the ReferenceFiles parameter, which is an ant path specification. The old 'references' string is still retained.

• An 'extraoptions' attribute enables the build file to include any CSC options which are not explicitly supported in the CSC task.

Internal changes

• Some minor refactoring (move common code a method)

• Application of Jedits JavaStyle task resulted in a major reshaping of the codebase and the insertion of a blank line every second line. Significant effort was required to revert some (but not all) changes.

• Removed throws clause from methods which can't throw exceptions

The test harness has been expanded to include unicode source file (the build works but the rest of the system has 'issues' with high unicode package and method names)

Version 0.2

First public edition, added to the ant cvs tree. Tested on the PDC build of the dotnet SDK only, and still immature. The command execution code was refactored out into a

'NetCommand' class for re-use. The Ilasm task was added at this time.

Version 0.1

Initial proof of concept; very rudimentary support for CSC only.

10.2 ANTLR

Description

Invokes the ANTLR Translator generator on a grammar file.

To use the ANTLR task, set the target attribute to the name of the grammar file to process.

Optionally, you can also set the outputdirectory to write the generated file to a specific directory. Otherwise ANTLR writes the generated files to the directory containing the grammar file.

This task only invokes ANTLR if the grammar file is newer than the generated files.

Antlr 2.7.1 Note: To successfully run ANTLR, your best option is probably to build the whole

jar with the provided script mkalljar and drop the resulting jar (about 300KB) into

${ant.home}/lib. Dropping the default jar (70KB) is probably not enough for most needs and your only option will be to add ANTLR home directory to your classpath as described in

ANTLR install.html document.

Antlr 2.7.2 Note: Instead of the above, you will need antlrall.jar that can be created by the

antlr-all.jar target of the Makefile provided with the download.

Parameters

Attribute

target html diagnostic trace traceParser

Description

The grammar file to process. outputdirectory The directory to write the generated files to. If not set, the files are written to the directory containing the grammar file.

No glib debug

An optional super grammar file that the target grammar overrides. This feature is only needed for advanced vocabularies.

When set to "yes", this flag adds code to the generated parser that will launch the ParseView debugger upon invocation. The default is "no".

Note: ParseView is a separate component that needs to be installed or your grammar will have compilation errors.

No

No

Emit an html version of the grammar with hyperlinked actions.

Generates a text file with debugging infomation based on the target grammar.

Required

Yes

No

No

Forces all rules to call traceIn/traceOut if set to "yes". The default is "no". No

Only forces parser rules to call traceIn/traceOut if set to "yes". The default is "no".

No traceLexer Only forces lexer rules to call traceIn/traceOut if set to "yes". The default is "no". traceTreeWalker Only forces tree walker rules to call traceIn/traceOut if set to "yes". The default is "no". dir The directory to invoke the VM in.

No

No

No

Nested Elements

ANTLR supports a nested <classpath> element, that represents a PATH like structure . It is given as a convenience if you have to specify the original ANTLR directory. In most cases, dropping the appropriate ANTLR jar in the normal Ant lib repository will be enough.

jvmarg

179/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Additional parameters may be passed to the new VM via nested <jvmarg> attributes, for example:

<antlr target="...">

<jvmarg value="-Djava.compiler=NONE"/>

...

</antlr> would run ANTLR in a VM without JIT.

<jvmarg> allows all attributes described in Command line arguments .

Example

<antlr

target="etc/java.g"

outputdirectory="build/src"

/>

This invokes ANTLR on grammar file etc/java.g, writing the generated files to build/src.

10.3 Cab

Description

The cab task creates Microsoft cab archive files. It is invoked similar to the jar or zip tasks.

This task will work on Windows using the external cabarc tool (provided by Microsoft) which must be located in your executable path.

To use this task on other platforms you need to download and compile libcabinet from http://trill.cis.fordham.edu/~barbacha/cabinet_library/ .

See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes basedir

) as well as the nested <include>, <exclude> and <patternset> elements.

Parameters

Attribute

cabfile basedir verbose compress options includes

Description

the name of the cab file to create. the directory to start archiving files from. set to "yes" if you want to see the output from the cabarc tool. defaults to

"no". set to "no" to store files without compressing. defaults to "yes". use to set additional command-line options for the cabarc tool. should not normally be necessary. comma- or space-separated list of patterns of files that must be included.

All files are included when omitted. the name of a file. Each line of this file is taken to be an include pattern includesfile excludes excludesfile comma- or space-separated list of patterns of files that must be excluded.

No files (except default excludes) are excluded when omitted. the name of a file. Each line of this file is taken to be an exclude pattern defaultexcludes indicates whether default excludes should be used or not ("yes"/"no").

Parameters specified as nested elements fileset

The cab task supports any number of nested <fileset> elements to specify the files to be included in the archive.

Examples

<cab cabfile="${dist}/manual.cab"

basedir="htdocs/manual"

/> cabs all files in the htdocs/manual directory into a file called manual.cab in the ${dist} directory.

<cab cabfile="${dist}/manual.cab"

basedir="htdocs/manual"

excludes="mydocs/**, **/todo.html"

/> cabs all files in the htdocs/manual directory into a file called manual.cab in the ${dist} directory. Files in the directory mydocs, or files with the name todo.html are excluded.

<cab cabfile="${dist}/manual.cab"

basedir="htdocs/manual"

includes="api/**/*.html"

excludes="**/todo.html"

verbose="yes"

/>

Cab all files in the htdocs/manual directory into a file called manual.cab in the ${dist} directory. Only html files under the directory api are archived, and files with the name todo.html are excluded. Output from the cabarc tool is displayed in the build output.

10.6 Depend

A task to manage Java class file dependencies.

Description

The depend task works by determining which classes are out of date with respect to their source and then removing the class files of any other classes which depend on the out-ofdate classes.

To determine the class dependencies, the depend task analyses the class files of all class files passed to it. Depend does not parse your source code in any way but relies upon the class references encoded into the class files by the compiler. This is generally faster than parsing the Java source.

To learn more about how this information is obtained from the class files, please refer to the

Java Virtual Machine Specification

Since a class' dependencies only change when the class itself changes, the depend task is able to cache dependency information. Only those class files which have changed will have their dependency information re-analysed. Note that if you change a class' dependencies by changing the source, it will be recompiled anyway. You can examine the dependency files created to understand the dependencies of your classes. Please do not rely, however, on the format of the information, as it may change in a later release.

185/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Once depend discovers all of the class dependencies, it "inverts" this relation to determine, for each class, which other classes are dependent upon it. This "affects" list is used to discover which classes are invalidated by the out of date class. The class files of the invalidated classes are removed, triggering the compilation of the affected classes.

The depend task supports an attribute, "closure" which controls whether depend will only consider direct class-class relationships or whether it will also consider transitive, indirect relationships. For example, say there are three classes, A, which depends on B, which inturn depend on C. Now say that class C is out of date. Without closure, only class B would be removed by depend. With closure set, class A would also be removed. Normally direct relationships are sufficient - it is unusual for a class to depend on another without having a direct relationship. With closure set, you will notice that depend typically removes far more class files.

The classpath attribute for <depend> is optional. If it is present, depend will check class dependencies against classes and jars on this classpath. Any classes which depend on an element from this classpath and which are older than that element will be deleted. A typical example where you would use this facility would be where you are building a utility jar and want to make sure classes which are out of date with respect to this jar are rebuilt. You should not include jars in this classpath which you do not expect to change, such as the

JDK runtime jar or third party jars, since doing so will just slow down the dependency check. This means that if you do use a classpath for the depend task it may be different from the classpath necessary to actually compile your code.

Performance

The performance of the depend task is dependent on a number of factors such as class relationship complexity and how many class files are out of date. The decision about whether it is cheaper to just recompile all classes or to use the depend task will depend on the size of your project and how interrelated your classes are.

Limitations

There are some source dependencies which depend will not detect.

• If the Java compiler optimizes away a class relationship, there can be a source dependency without a class dependency.

• Non public classes cause two problems. Firstly depend cannot relate the class file to a source file. In the future this may be addressed using the source file attribute in the classfile. Secondly, neither depend nor the compiler tasks can detect when a non public class is missing. Inner classes are handled by the depend task.

The most obvious example of these limitations is that the task can't tell which classes to recompile when a constant primitive data type exported by other classes is changed. For example, a change in the definition of something like public final class Constants {

public final static boolean DEBUG=false;

} will not be picked up by other classes.

Parameters

186/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Attribute Description

srcDir This is the directory where the source exists. depend will examine this to determine which classes are out of date. If you use multiple source directories you can pass this attribute a path of source directories. destDir This is the root directory of the class files which will be analysed. If this is not present, the srcdir is used.

Required

Yes

No cache This is a directory in which depend can store and retrieve dependency information. If this is not present, depend will not use a cache

No closure This attribute controls whether depend only removes classes which directly depend on out of date classes. If this is set to true, depend will traverse the class

No dependency graph deleting all affected classes. Defaults to false dump If true the dependency information will be written to the debug level log No classpath The classpath containg jars and classes for which <depend> should also check dependencies

No

Parameters specified as nested elements

The depend task's classpath attribute is a PATH-like structure and can also be set via a nested <classpath> element.

Additionally, this task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes srcdir), as well as the nested <include>, <exclude>, and <patternset> elements.

Examples

<depend srcdir="${java.dir}"

destdir="${build.classes}"

cache="depcache"

closure="yes"/> removes any classes in the ${build.classes} directory that depend on out-of-date classes.

Classes are considered out-of-date with respect to the source in the ${java.dir} directory, using the same mechanism as the <javac> task. In this example, the <depend> task caches its dependency information in the depcache directory.

<depend srcdir="${java.dir}" destdir="${build.classes}"

cache="depcache" closure="yes">

<include name="**/*.java"/>

<excludesfile name="${java.dir}/build_excludes"/>

</depend> does the same as the previous example, but explicitly includes all .java files, except those that match the list given in ${java.dir}/build_excludes.

10.7.1 Introduction

Ant provides a number of optional tasks for developing Enterprise Java Beans (EJBs) . In general these tasks are specific to the particular vendor's EJB Server.

At present the tasks support:

• Borland Application Server 4.5

• iPlanet Application Server 6.0

• JBoss 2.1

and above EJB servers

• Weblogic 4.5.1 through to 7.0 EJB servers

• JOnAS 2.4.x and 2.5 Open Source EJB server

• IBM WebSphere 4.0

Over time we expect further optional tasks to support additional EJB Servers.

10.7.2.1 DDCREATOR

Description:

ddcreator will compile a set of Weblogic text-based deployment descriptors into a serialized

EJB deployment descriptor. The selection of which of the text-based descriptors are to be compiled is based on the standard Ant include and exclude selection mechanisms.

Parameters:

Attribute Description Required

descriptors This is the base directory from which descriptors are selected. Yes dest The directory where the serialized deployment descriptors will be written Yes classpath This is the classpath to use to run the underlying weblogic ddcreator tool. No

This must include the weblogic.ejb.utils.DDCreator class

Examples

<ddcreator descriptors="${dd.dir}"

dest="${gen.classes}"

classpath="${descriptorbuild.classpath}">

<include name="*.txt"/>

Ant Manual 1.5.4 12/9/2003 7:47 PM

</ddcreator>

10.7.2.2 EJBC

Description:

The ejbc task will run Weblogic's ejbc tool. This tool will take a serialized deployment descriptor, examine the various EJB interfaces and bean classes and then generate the required support classes necessary to deploy the bean in a Weblogic EJB container. This will include the RMI stubs and skeletons as well as the classes which implement the bean's home and remote interfaces.

The ant task which runs this tool is able to compile several beans in a single operation. The beans to be compiled are selected by including their serialized deployment descriptors. The standard ant include and exclude constructs can be used to select the deployment descriptors to be included.

Each descriptor is examined to determine whether the generated classes are out of date and need to be regenerated. The deployment descriptor is de-serialized to discover the home, remote and implementation classes. The corresponding source files are determined and checked to see their modification times. These times and the modification time of the serialized descriptor itself are compared with the modification time of the generated classes.

If the generated classes are not present or are out of date, the ejbc tool is run to generate new versions.

Parameters:

Attribute Description Required

descriptors Yes dest manifest src classpath

This is the base directory from which the serialized deployment descriptors are selected.

The base directory where the generated classes, RIM stubs and RMI skeletons are written

The name of a manifest file to be written. This manifest will contain an entry for each EJB processed

The base directory of the source tree containing the source files of the home interface, remote interface and bean implementation classes.

This classpath must include both the weblogic.ejbc class and the class files of the bean, home interface, remote interface, etc of the bean being pro cessed.

Yes

Yes

Yes

No keepgenerated Controls whether ejbc will keep the intermediate Java files used to build the class files.

This can be useful when debugging.

Examples

<ejbc descriptors="${gen.classes}"

No, defaults to false.

src="${src.dir}"

dest="${gen.classes}"

manifest="${build.manifest}"

classpath="${descriptorbuild.classpath}">

<include name="*.ser"/>

</ejbc>

10.7.2.3 IPLANET-EJBC

Description:

189/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Task to compile EJB stubs and skeletons for the iPlanet Application Server 6.0. Given a standard EJB 1.1 XML descriptor as well as an iAS-specific EJB descriptor, this task will generate the stubs and skeletons required to deploy the EJB to iAS. Since the XML descriptors can include multiple EJBs, this is a convenient way of specifying many EJBs in a single Ant task.

For each EJB specified, the task will locate the three classes that comprise the EJB in the destination directory. If these class files cannot be located in the destination directory, the task will fail. The task will also attempt to locate the EJB stubs and skeletons in this directory. If found, the timestamps on the stubs and skeletons will be checked to ensure they are up to date. Only if these files cannot be found or if they are out of date will the iAS ejbc utility be called to generate new stubs and skeletons.

Parameters:

Attribute Description Required

ejbdescriptor Standard EJB 1.1 XML descriptor (typically titled "ejb-jar.xml"). iasdescriptor iAS-specific EJB XML descriptor (typically titled "ias-ejb-jar.xml").

Yes

Yes dest The is the base directory where the RMI stubs and skeletons are written. In addition, the class files for each bean (home interface, remote interface, and

Yes

EJB implementation) must be found in this directory.

No classpath keepgenerated Indicates whether or not the Java source files which are generated by ejbc will be saved or automatically deleted. If "yes", the source files will be retained. If omitted, it defaults to "no". debug

The classpath used when generating EJB stubs and skeletons. If omitted, the classpath specified when Ant was started will be used. Nested

"classpath" elements may also be used.

Indicates whether or not the ejbc utility should log additional debugging statements to the standard output. If "yes", the additional debugging statements will be generated. If omitted, it defaults to "no".

No

No iashome May be used to specify the "home" directory for this iAS installation. This is used to find the ejbc utility if it isn't included in the user's system path. If specified, it should refer to the "[install-location]/iplanet/ias6/ias" directory.

If omitted, the ejbc utility must be on the user's system path.

Examples

<iplanet-ejbc ejbdescriptor="ejb-jar.xml"

No

iasdescriptor="ias-ejb-jar.xml"

dest="${build.classesdir}"

classpath="${ias.ejbc.cpath}"/>

<iplanet-ejbc ejbdescriptor="ejb-jar.xml"

iasdescriptor="ias-ejb-jar.xml"

dest="${build.classesdir}"

keepgenerated="yes"

debug="yes"

iashome="${ias.home}">

<classpath>

<pathelement path="."/>

<pathelement path="${build.classpath}"/>

</classpath>

191/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Examples

This example shows the use of wlrun to run a server under Weblogic 5.1

<wlrun taskname="myserver"

classpath="${weblogic.boot.classpath}"

wlclasspath="${weblogic.classes}:${code.jars}"

name="myserver"

home="${weblogic.home}"

properties="myserver/myserver.properties"/>

This example shows wlrun being used to run the petstore server under Weblogic 6.0

<wlrun taskname="petstore"

classpath="${weblogic.classes}"

name="petstoreServer"

domain="petstore"

home="${weblogic.home}"

password="petstorePassword"

beahome="${bea.home}"/>

10.7.2.5 WLSTOP

Description:

The wlstop task is used to stop a weblogic instance which is currently running. To shut down an instance you must supply both a username and a password. These will be stored in the clear in the build script used to stop the instance. For security reasons, this task is therefore only appropriate in a development environment.

This task works for most version of Weblogic, including 6.0. You need to specify the BEA

Home to have this task work correctly under 6.0

Parameters:

Attribute Description

BEAHome This attribute selects Weblogic 6.0 shutdown. classpath The classpath to be used with the Java Virtual Machine that runs the Weblogic

Shutdown command. user The username of the account which will be used to shutdown the server password The password for the account specified in the user parameter. url The URL which describes the port to which the server is listening for T3 connections. For example, t3://localhost:7001 delay The delay in seconds after which the server will stop. This defaults to an immediate shutdown.

Nested Element

The classpath of the wlstop task can be set by a <classpath> nested element.

Examples

This example show the shutdown for a Weblogic 6.0 server

<wlstop classpath="${weblogic.classes}"

user="system"

Required

password="foobar"

beahome="${bea.home}"/>

10.7.2.6 EJBJAR

Description:

This task is designed to support building of EJB jar files (EJB 1.1 & 2.0). Support is currently provided for 'vanilla' EJB jar files - i.e. those containing only the user generated class files and the standard deployment descriptor. Nested elements provide support for vendor specific deployment tools. These currently include:

• Borland Application Server 4.5

• iPlanet Application Server 6.0

• JBoss 2.1 and above

• Weblogic 5.1/6.0 session/entity beans using the weblogic.ejbc tool

• IBM WebSphere 4.0

TOPLink for WebLogic 2.5.1-enabled entity beans

• JOnAS 2.4.x and 2.5 Open Source EJB server

The task works as a directory scanning task, and performs an action for each deployment descriptor found. As such the includes and excludes should be set to ensure that all desired

EJB descriptors are found, but no application server descriptors are found. For each descriptor found, ejbjar will parse the deployment descriptor to determine the necessary class files which implement the bean. These files are assembled along with the deployment descriptors into a well formed EJB jar file. Any support files which need to be included in the generated jar can be added with the <support> nested element. For each class included in the jar, ejbjar will scan for any super classes or super interfaces. These will be added to the generated jar.

If no nested vendor-specific deployment elements are present, the task will simply generate a generic EJB jar. Such jars are typically used as the input to vendor-specific deployment tools. For each nested deployment element, a vendor specific deployment tool is run to generate a jar file ready for deployment in that vendor's EJB container.

The jar files are only built if they are out of date. Each deployment tool element will examine its target jar file and determine if it is out of date with respect to the class files and deployment descriptors that make up the bean. If any of these files are newer than the jar file the jar will be rebuilt otherwise a message is logged that the jar file is up to date.

The task uses the jakarta-BCEL framework to extract all dependent classes. This means that, in addition to the classes that are mentioned in the deployment descriptor, any classes that these depend on are also automatically included in the jar file.

Naming Convention

Ejbjar handles the processing of multiple beans, and it uses a set of naming conventions to determine the name of the generated EJB jars. The naming convention that is used is controlled by the "naming" attribute. It supports the following values

• descriptor

193/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

This is the default naming scheme. The name of the generated bean is derived from the name of the deployment descriptor. For an Account bean, for example, the deployment descriptor would be named Account-ejb-jar.xml. Vendor specific descriptors are located using the same naming convention. The weblogic bean, for example, would be named Account-weblogic-ejb-jar.xml. Under this arrangement, the deployment descriptors can be separated from the code implementing the beans, which can be useful when the same bean code is deployed in separate beans.

This scheme is useful when you are using one bean per EJB jar and where you may be deploying the same bean classes in different beans, with different deployment characteristics.

• ejb-name

This naming scheme uses the <ejb-name> element from the deployment descriptor to determine the bean name. In this situation, the descriptors normally use the generic descriptor names, such as ejb-jar.xml along with any associated vendor specific descriptor names. For example, If the value of the <ejb-name> were to be given in the deployment descriptor as follows:

<ejb-jar>

<enterprise-beans>

<entity>

<ejb-name>Sample</ejb-name>

<home>org.apache.ant.ejbsample.SampleHome</home> then the name of the generated bean would be Sample.jar

This scheme is useful where you want to use the standard deployment descriptor names, which may be more compatible with other EJB tools. This scheme must have one bean per jar.

• directory

In this mode, the name of the generated bean jar is derived from the directory containing the deployment descriptors. Again the deployment descriptors typically use the standard filenames. For example, if the path to the deployment descriptor is

/home/user/dev/appserver/dd/sample

, then the generated bean will be named sample.jar

This scheme is also useful when you want to use standard style descriptor names. It is often most useful when the descriptors are located in the same directory as the bean source code, although that is not mandatory. This scheme can handle multiple beans per jar.

• basejarname

The final scheme supported by the <ejbjar> task is used when you want to specify the generated bean jar name directly. In this case the name of the generated jar is specified by the "basejarname" attribute. Since all generated beans will have the

194/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

same name, this task should be only used when each descriptor is in its own directory.

This scheme is most appropriate when you are using multiple beans per jar and only process a single deployment descriptor. You typically want to specify the name of the jar and not derive it from the beans in the jar.

Dependencies

In addition to the bean classes, ejbjar is able to ad additional classes to the generated ejbjar. These classes are typically the support classes which are used by the bean's classes or as parameters to the bean's methods.

In versions of Ant prior to 1.5, ejbjar used reflection and attempted to add the super classes and super interfaces of the bean classes. For this technique to work the bean classes had to be loaded into Ant's JVM. This was not always possible due to class dependencies.

The ejbjar task in Ant releases 1.5 and later uses the jakarta-BCEL library to analyze the bean's class files directly, rather than loading them into the JVM. This also allows ejbjar to add all of the required support classes for a bean and not just super classes.

In Ant 1.5, a new attribute, dependency has been introduced to allow the buildfile to control what additional classes are added to the generated jar. It takes three possible values

• none

- only the bean classes and interfaces described in the bean's descriptor are added to the jar.

• super

- this is the default value and replicates the original ejbjar behaviour where super classes and super interfaces are added to the jar

• full

- In this mode all classes used by the bean's classes and interfaces are added to the jar

The super and full values require the jakarta-BCEL library to be available. If it is not, ejbjar will drop back to the behaviour corresponding to the value none.

Parameters:

Attribute

descriptordir srcdir destdir naming

Description

The base directory under which to scan for EJB deployment descriptors. If this attribute is not specified, then the deployment descriptors must be located in the directory specified by the

'srcdir' attribute.

The base directory containing the .class files that make up the bean. Included are the home - remote - pk- and implementation- classes and all classes, that these depend on. Note that this can be the same as the descriptordir if all files are in the same directory tree.

Required

No

Yes

The base directory into which generated jar files are deposited.

Jar files are deposited in directories corresponding to their location within the descriptordir namespace. Note that this attribute is only used if the task is generating generic jars (i.e. no vendor-specific deployment elements have been specified).

Yes

Controls the naming convention used to name generated EJB jars. No

195/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Please refer to the description above. basejarname The base name that is used for the generated jar files. If this attribute is specified, the generic jar file name will use this value as the prefix (followed by the value specified in the

'genericjarsuffix' attribute) and the resultant ejb jar file (followed by any suffix specified in the nested element).

No basenameterminator String value used to substring out a string from the name of each deployment descriptor found, which is then used to locate related deployment descriptors (e.g. the WebLogic descriptors). For example, a basename of '.' and a deployment descriptor called

'FooBean.ejb-jar.xml' would result in a basename of 'FooBean' which would then be used to find FooBean.weblogic-ejb-jar.xml and FooBean.weblogic-cmp-rdbms-jar.xml, as well as to create the filenames of the jar files as FooBean-generic.jar and FooBeanwl.jar. This attribute is not used if the 'basejarname' attribute is specified.

No, defaults to '-'. genericjarsuffix classpath

String value appended to the basename of the deployment descriptor to create the filename of the generic EJB jar file.

No, defaults to 'generic.jar'.

No. This classpath is used when resolving classes which are to be added to the jar. Typically nested deployment tool elements will also support a classpath which will be combined with this classpath when resolving classes flatdestdir Set this attribute to true if you want all generated jars to be placed in the root of the destdir, rather than according to the location of the deployment descriptor within the descriptor dir hierarchy.

No. dependency This attribute controls which additional classes and interfaces are added to the jar. Please refer to the description above

No.

Nested Elements

In addition to the vendor specific nested elements, the ejbjar task provides three nested elements.

Classpath

The <classpath> nested element allows the classpath to be set. It is useful when setting the classpath from a reference path. In all other respects the behaviour is the same as the classpath attribute.

dtd

The <dtd> element is used to specify the local location of DTDs to be used when parsing the EJB deployment descriptor. Using a local DTD is much faster than loading the DTD across the net. If you are running ejbjar behind a firewall you may not even be able to access the remote DTD. The supported vendor-specific nested elements know the location of the required DTDs within the vendor class hierarchy and, in general, this means <dtd> elements are not required. It does mean, however, that the vendor's class hierarchy must be available in the classpath when Ant is started. If your want to run Ant without requiring the vendor classes in the classpath, you would need to use a <dtd> element.

Attribute Description Required

publicId The public Id of the DTD for which the location is being provided Yes location The location of the local copy of the DTD. This can either be a file or a resource Yes

196/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

loadable from the classpath.

support

The <support> nested element is used to supply additional classes (files) to be included in the generated jars. The <support> element is a FileSet , so it can either reference a fileset declared elsewhere or it can be defined in-place with the appropriate <include> and

<exclude> nested elements. The files in the support fileset are added into the generated

EJB jar in the same relative location as their location within the support fileset. Note that when ejbjar generates more than one jar file, the support files are added to each one.

10.7.3 Vendor-specific deployment elements

Each vendor-specific nested element controls the generation of a deployable jar specific to that vendor's EJB container. The parameters for each supported deployment element are detailed here.

10.7.3.1 JBOSS ELEMENT

The jboss element searches for the JBoss specific deployment descriptors and adds them to the final ejb jar file. JBoss has two deployment descriptors jboss.xml and jaws.xml (for container manager persistence only). The JBoss server uses hot deployment and does not require compilation of additional stubs and skeletons.

Attribute Description Required

Yes destdir The base directory into which the generated weblogic ready jar files are deposited. Jar files are deposited in directories corresponding to their location within the descriptordir namespace. genericjarsuffix A generic jar is generated as an intermediate step in build the weblogic deployment jar. The suffix used to generate the generic jar file is not particularly important unless it is desired to keep the generic jar file. It should not, however, be the same as the suffix setting. suffix String value appended to the basename of the deployment descriptor to create the filename of the JBoss EJB jar file.

No, defaults to

'-generic.jar'.

No, defaults to

'.jar'. keepgeneric This controls whether the generic file used as input to ejbc is retained. No, defaults to false

10.7.3.2 WEBLOGIC ELEMENT

The weblogic element is used to control the weblogic.ejbc compiler for generating weblogic

EJB jars. Prior to Ant 1.3, the method of locating CMP descriptors was to use the ejbjar naming convention. So if your ejb-jar was called, Customer-ejb-jar.xml, your weblogic descriptor was called Customer- weblogic -ejb-jar.xml and your CMP descriptor had to be

Customer-weblogic -cmp- rdbms-jar.xml. In addition, the <type-storage> element in the weblogic descriptor had to be set to the standard name META-INF/weblogic -cmp-rdbms- jar.xml, as that is where the CMP descriptor was mapped to in the generated jar.

There are a few problems with this scheme. It does not allow for more than one CMP descriptor to be defined in a jar and it is not compatible with the deployment descriptors generated by some tools.

In Ant 1.3, ejbjar parses the weblogic deployment descriptor to discover the CMP descriptors, which are then included automatically. This behaviour is controlled by the newCMP attribute. Note that if you move to the new method of determining CMP descriptors, you will need to update your weblogic deployment descriptor's <type-storage> element. In the above example, you would define this as META-INF/Customer-weblogic cmp-rdbms-jar.xml.

197/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Attribute

destdir

Description Required

The base directory into which the generated weblogic ready jar files are deposited. Jar files are deposited in directories corresponding to their

Yes location within the descriptordir namespace. genericjarsuffix A generic jar is generated as an intermediate step in build the weblogic deployment jar. The suffix used to generate the generic jar file is not particularly important unless it is desired to keep the generic jar file. It should not, however, be the same as the suffix setting.

No, defaults to 'generic.jar'. suffix String value a ppended to the basename of the deployment descriptor to create the filename of the WebLogic EJB jar file.

No, defaults to '.jar'. classpath wlclasspath

The classpath to be used when running the weblogic ejbc tool. Note that this tool typically requires the classes that make up the bean to be available on the classpath. Currently, however, this will cause the ejbc tool to be run in a separate VM

No

Weblogic 6.0 will give a warning if the home and remote interfaces of a bean are on the system classpath used to run weblogic.ejbc. In that case, the standard weblogic classes should be set with this attribute (or equivalent nested element) and the home and remote interfaces located with the standard classpath attribute

No keepgeneric This controls whether the g eneric file used as input to ejbc is retained. No, defaults to false compiler This allows for the selection of a different compiler to be used for the compilation of the generated Java files. This could be set, for example, to Jikes to compile with the Jikes compiler. If this is not set and the build.compiler property is set to jikes, the Jikes compiler will be used. If this is not desired, the value "default" may be given to use the default compiler

No rebuild This flag controls whether weblogic.ejbc is always invoked to build the jar file. In certain circumstances, such as when only a bean class has been changed, the jar can be generated by merely replacing the changed classes and not rerunning ejbc. Setting this to false will reduce the time to run ejbjar.

No, defaults to true. keepgenerated Controls whether weblogic will keep the generated Java files used to build the class files added to the jar. This can be useful when debugging

No, defaults to false. args Any additional arguments to be passed to the weblogic.ejbc tool. No. weblogicdtd Deprecated. Defines the location of the ejb-jar DTD in the weblogic class hierarchy. This should not be necessary if you have weblogic in your classpath. If you do not, you should use a nested <dtd> element, described above. If you do choose to use an attribute, you should use a nested <dtd> element.

No. wldtd ejbdtd

Deprecated. Defines the location of the weblogic-ejb-jar DTD which covers the Weblogic specific deployment descriptors. This should not be necessary if you have weblogic in your classpath. If you do not, you should use a nested <dtd> element, described above.

No.

No. Deprecated. Defines the location of the ejb-jar DTD in the weblogic class hierarchy. This should not be necessary if you have weblogic in your classpath. If you do not, you should use a nested <dtd> element, described above. newCMP oldCMP

If this is set to true, the new method for locating CMP descriptors will be used.

Deprecated This is an antonym for newCMP which should be used instead.

No. Defaults to false

No.

198/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

noEJBC ejbcclass jvmargs

If this attribute is set to true, Weblogic's ejbc will not be run on the EJB jar. Use this if you prefer to run ejbc at deployment time.

No.

Specifies the classname of the ejbc compiler. Normally ejbjar determines the appropriate class based on the DTD used for the EJB.

The EJB 2.0 compiler featured in weblogic 6 has, however, been deprecated in version 7. When using with version 7 this attribute should be set to "weblogic.ejbc" to avoid the deprecation warning.

Any additional arguments to be passed to the Virtual Machine running weblogic.ejbc tool. For example to set the memory size, this could be jvmargs="-Xmx128m"

No.

No. jvmdebuglevel Sets the weblogic.StdoutSeverityLevel to use when running the Virtual

Machine that executes ejbc. Set to 16 to avoid the warnings about EJB

Home and Remotes being in the classpath

No. outputdir If set ejbc will be given this directory as the output destination rather than a jar file. This allows for the generation of "exploded" jars.

No.

The weblogic nested element supports three nested elements. The first two, <classpath> and <wlclasspath>, are used to set the respective classpaths. These nested elements are useful when setting up class paths using reference Ids. The last, <sysproperty>, allows Java system properties to be set during the compiler run. This turns out to be necessary for supporting CMP EJB compilation in all environments.

10.7.3.3 TOPLINK FOR WEBLOGIC ELEMENT - DEPRECATED

The toplink element is no longer required. Toplink beans can now be built with the standard weblogic element, as long as the newCMP attribute is set to "true"

The TopLink element is used to handle beans which use Toplink for the CMP operations. It is derived from the standard weblogic element so it supports the same set of attributes plus these additional attributes

Attribute Description Required

Yes toplinkdescriptor This specifies the name of the TOPLink deployment descriptor file contained in the 'descriptordir' directory. toplinkdtd This specifies the location of the TOPLink DTD file. This can be a file path or a file URL.

This attribute is not required, but using a local DTD is recommended.

Examples

No, defaults to dtd file at www.objectpeople.com.

This example shows ejbjar being used to generate deployment jars using a Weblogic EJB container. This example requires the naming standard to be used for the deployment descriptors. Using this format will create a ejb jar file for each variation of '*-ejb-jar.xml' that is found in the deployment descriptor directory.

<ejbjar srcdir="${build.classes}"

descriptordir="${descriptor.dir}">

<weblogic destdir="${deploymentjars.dir}"

classpath="${descriptorbuild.classpath}"/>

<include name="**/*-ejb-jar.xml"/>

<exclude name="**/*weblogic*.xml"/>

</ejbjar>

199/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

If weblogic is not in the Ant classpath, the following example shows how to specify the location of the weblogic DTDs. This example also show the use of a nested classpath element.

<ejbjar descriptordir="${src.dir}" srcdir="${build.classes}">

<weblogic destdir="${deployment.webshop.dir}"

keepgeneric="true"

args="-g -keepgenerated ${ejbc.compiler}"

suffix=".jar"

oldCMP="false">

<classpath>

<pathelement path="${descriptorbuild.classpath}"/>

</classpath>

</weblogic>

<include name="**/*-ejb-jar.xml"/>

<exclude name="**/*-weblogic-ejb-jar.xml"/>

<dtd publicId="-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans

1.1//EN" location="${weblogic.home}/classes/weblogic/ejb/deployment/xml/ejb-jar.dtd"/>

<dtd publicId="-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB//EN" location="${weblogic.home}/classes/weblogic/ejb/deployment/xml/weblogic-ejbjar.dtd"/>

</ejbjar>

This example shows ejbjar being used to generate a single deployment jar using a Weblogic

EJB container. This example does not require the deployment descriptors to use the naming standard. This will create only one ejb jar file - 'TheEJBJar.jar'.

<ejbjar srcdir="${build.classes}"

descriptordir="${descriptor.dir}"

basejarname="TheEJBJar">

<weblogic destdir="${deploymentjars.dir}"

classpath="${descriptorbuild.classpath}"/>

<include name="**/ejb-jar.xml"/>

<exclude name="**/weblogic*.xml"/>

</ejbjar>

This example shows ejbjar being used to generate deployment jars for a TOPLink-enabled entity bean using a Weblogic EJB container. This example does not require the deployment descriptors to use the naming standard. This will create only one TOPLink-enabled ejb jar file - 'Address.jar'.

<ejbjar srcdir="${build.dir}"

destdir="${solant.ejb.dir}"

descriptordir="${descriptor.dir}"

basejarname="Address">

<weblogictoplink destdir="${solant.ejb.dir}"

classpath="${java.class.path}"

keepgeneric="false"

toplinkdescriptor="Address.xml"

toplinkdtd="file:///dtdfiles/toplink-cmp_2_5_1.dtd"

suffix=".jar"/>

<include name="**/ejb-jar.xml"/>

200/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<exclude name="**/weblogic-ejb-jar.xml"/>

</ejbjar>

This final example shows how you would set-up ejbjar under Weblogic 6.0. It also shows the use of the <support> element to add support files

<ejbjar descriptordir="${dd.dir}" srcdir="${build.classes.server}">

<include name="**/*-ejb-jar.xml"/>

<exclude name="**/*-weblogic-ejb-jar.xml"/>

<support dir="${build.classes.server}">

<include name="**/*.class"/>

</support>

<weblogic destdir="${deployment.dir}"

keepgeneric="true"

suffix=".jar"

rebuild="false">

<classpath>

<pathelement path="${build.classes.server}"/>

</classpath>

<wlclasspath>

<pathelement path="${weblogic.classes}"/>

</wlclasspath>

</weblogic>

</ejbjar>

10.7.3.4 WEBSPHERE ELEMENT

The websphere element searches for the websphere specific deployment descriptors and adds them to the final ejb jar file. Websphere has two specific descriptors for session beans:

• ibm-ejb-jar-bnd.xmi

• ibm-ejb-jar-ext.xmi and another two for container managed entity beans:

• Map.mapxmi

Schema.dbxmi

In terms of WebSphere, the generation of container code and stubs is called deployment.

This step can be performed by the websphere element as part of the jar generation process.

If the switch ejbdeploy is on, the ejbdeploy tool from the websphere toolset is called for every ejb-jar. Unfortunately, this step only works, if you use the ibm jdk. Otherwise, the rmic (called by ejbdeploy) throws a ClassFormatError. Be sure to switch ejbdeploy off, if run ant with sun jdk.

For the websphere element to work, you have to provide a complete classpath, that contains all classes, that are required to reflect the bean classes. For ejbdeploy to work, you must also provide the classpath of the ejbdeploy tool and set the websphere.home property

(look at the examples below).

Attribute

destdir ejbdeploy

Description Required

The base directory into which the generated weblogic ready jar files are deposited. Jar files are deposited in directories corresponding to their location within the descriptordir namespace.

Yes

Decides wether ejbdeploy is called. When you set this to No, defaults to true

201/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

suffix keepgeneric true, be sure, to run ant with the ibm jdk.

String value appended to the basename of the deployment descriptor to create the filename of the WebLogic EJB jar file.

No, defaults to '.jar'.

This controls whether the generic file used as input to ejbdeploy is retained.

No, defaults to false rebuild tempdir dbName dbSchema rmicOptions

This controls whether ejbdeploy is called although no changes have occurred.

A directory, where ejbdeploy will write temporary files

These options are passed to ejbdeploy. dbVendor This option is passed to ejbdeploy. Valid options are for example:

SQL92

DB2UDBAS400_V4R5

ORACLE_V8

INFORMIX_V92

SYBASE_V1192

MYSQL_V323

MSSQLSERVER_V7

This is also used to determine the name of the

Map.mapxmi and Schema.dbxmi files, for example

Account-DB2UDBWIN_V71-Map.mapxmi and Account-

DB2UDBWIN_V71-Schema.dbxmi. codegen quiet novalidate noinform trace use35MappingRules

These options are all passed to ejbdeploy. All options except 'quiet' default to false.

No, defaults to false

10.7.3.5 IPLANET APPLICATION SERVER (IAS) ELEMENT

The <iplanet< nested element is used to build iAS-specific stubs and skeletons and construct a JAR file which may be deployed to the iPlanet Application Server 6.0. The build process will always determine if the EJB stubs/skeletons and the EJB-JAR file are up to date, and it will do the minimum amount of work required.

Like the WebLogic element, a naming convention for the EJB descriptors is most commonly used to specify the name for the completed JAR file. For example, if the EJB descriptor ejb/Account-ejb-jar.xml is found in the descriptor directory, the iplanet element will search for an iAS-specific EJB descriptor file named ejb/Account-ias-ejb-jar.xml (if it isn't found, the task will fail) and a JAR file named ejb/Account.jar will be written in the destination directory. Note that when the EJB descriptors are added to the JAR file, they are automatically renamed META-INF/ejb-jar.xml and META-INF/ias-ejb-jar.xml.

Of course, this naming behaviour can be modified by specifying attributes in the ejbjar task

(for example, basejarname, basenameterminator, and flatdestdir) as well as the iplanet element (for example, suffix). Refer to the appropriate documentation for more details.

Parameters:

Attribute

destdir classpath

Description

keepgenerated Indicates whether or not the Java source files which are generated by ejbc will be saved or automatically deleted. If "yes", the source files will be retained. If omitted, it defaults to "no".

Required

The base directory into which the generated JAR files will be written. Each

JAR file is written in directories which correspond to their location within the

"descriptordir" namespace.

Yes

The classpath used when generating EJB stubs and skeletons. If omitted, the classpath specified in the "ejbjar" parent task will be used. If specified, the classpath elements will be prepended to the classpath specified in the parent "ejbjar" task. Note that nested "classpath" elements may also be used.

No

No debug iashome suffix

Indicates whether or not the e jbc utility should log additional debugging statements to the standard output. If "yes", the additional debugging statements will be generated. If omitted, it defaults to "no".

No

May be used to specify the "home" directory for this iAS installation. This is used to find the ejbc utility if it isn't included in the user's system path. If specified, it should refer to the [install-location]/iplanet/ias6/ias directory. If omitted, the ejbc utility must be on the user's system path.

No

String value appended to the JAR filename when creating each JAR. If No

203/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

omitted, it defaults to ".jar".

As noted above, the iplanet element supports additional <classpath> nested elements.

Examples

This example demonstrates the typical use of the <iplanet> nested element. It will name each EJB-JAR using the "basename" prepended to each standard EJB descriptor. For example, if the descriptor named "Account-ejb-jar.xml" is processed, the EJB-JAR will be named "Account.jar"

<ejbjar srcdir="${build.classesdir}"

descriptordir="${src}">

<iplanet destdir="${assemble.ejbjar}"

classpath="${ias.ejbc.cpath}"/>

<include name="**/*-ejb-jar.xml"/>

<exclude name="**/*ias-*.xml"/>

</ejbjar>

This exa mple demonstrates the use of a nested classpath element as well as some of the other optional attributes.

<ejbjar srcdir="${build.classesdir}"

descriptordir="${src}">

<iplanet destdir="${assemble.ejbjar}"

iashome="${ias.home}"

debug="yes"

keepgenerated="yes">

<classpath>

<pathelement path="."/>

<pathelement path="${build.classpath}"/>

</classpath>

</iplanet>

<include name="**/*-ejb-jar.xml"/>

<exclude name="**/*ias-*.xml"/>

</ejbjar>

This example demonstrates the use of basejarname attribute. In this case, the completed

EJB-JAR will be named "HelloWorld.jar" If multiple EJB descriptors might be found, care must be taken to ensure that the completed JAR files don't overwrite each other.

<ejbjar srcdir="${build.classesdir}"

descriptordir="${src}"

basejarname="HelloWorld">

<iplanet destdir="${assemble.ejbjar}"

classpath="${ias.ejbc.cpath}"/>

<include name="**/*-ejb-jar.xml"/>

<exclude name="**/*ias-*.xml"/>

</ejbjar>

204/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

This example demonstrates the use of the dtd nested element. If the local copies of the

DTDs are included in the classpath, they will be automatically referenced without the nested elements. In iAS 6.0 SP2, these local DTDs are found in the [iAS-install-directory]/APPS directory. In iAS 6.0 SP3, these local DTDs are found in the [iAS-install-directory]/dtd directory.

<ejbjar srcdir="${build.classesdir}"

descriptordir="${src}">

<iplanet destdir="${assemble.ejbjar}">

classpath="${ias.ejbc.cpath}"/>

<include name="**/*-ejb-jar.xml"/>

<exclude name="**/*ias-*.xml"/>

JavaBeans 1.0//EN"

location="${ias.home}/APPS/IASEjb_jar_1_0.dtd"/>

</ejbjar>

10.7.3.6 JONAS (JAVA OPEN APPLICATION SERVER) ELEMENT

The <jonas> nested element is used to build JOnAS-specific stubs and skeletons thanks to the GenIC specific tool, and construct a JAR file which may be deployed to the JOnAS

Application Server. The build process will always determine if the EJB stubs/skeletons and the EJB-JAR file are up to date, and it will do the minimum amount of work required.

Like the WebLogic element, a naming convention for the EJB descriptors is most commonly used to specify the name for the completed JAR file. For example, if the EJB descriptor ejb/Account-ejb-jar.xml

is found in the descriptor directory, the <jonas> element will search for a JOnAS-specific EJB descriptor file named ejb/Account-jonas-ejb-jar.xml and a JAR file named ejb/Account.jar will be written in the destination directory. But the

<jonas> element can also use the JOnAS naming convention. With the same example as below, the EJB descriptor can also be named ejb/Account.xml (no base name terminator here) in the descriptor directory. Then the <jonas> element will search for a JOnAS-specific

EJB descriptor file called ejb/jonas-Account.xml. This convention do not follow strictly the ejb-jar naming convention recommendation but is supported for backward compatibility with previous version of JOnAS.

Note that when the EJB descriptors are added to the JAR file, they are automatically renamed META-INF/ejb-jar.xml and META-INF/jonas-ejb-jar.xml.

Of course, this naming behavior can be modified by specifying attributes in the ejbjar task

(for example, basejarname, basenameterminator, and flatdestdir) as well as the iplanet element (for example, suffix). Refer to the appropriate documentation for more details.

Parameters:

Attribute

destdir jonasroot

Description Required

The base directory into which the generated JAR files will be written. Each

JAR file is written in directories which correspond to their location within the

"descriptordir" namespace.

Yes

The root directory for JOnAS. Yes

205/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

classpath The classpath used when generating EJB stubs and skeletons. If omitted, the classpath specified in the "ejbjar" parent task will be used. If specified, the classpath elements will be prepended to the classpath specified in the parent "ejbjar" task (see also the ORB attribute documentation below). Note that nested "classpath" elements may also be used.

No keepgenerated true if the intermediate Java source files generated by GenIC must be deleted or not. If omitted, it defaults to false. nocompil true if the generated source files must not be compiled via the java and rmi compilers. If omitted, it defaults to false.

No

No novalidation true if the XML deployment descriptors must be parsed without validation. If omitted, it defaults to false.

No javac Java compiler to use. If omitted, it defaults to the value of build.compiler property.

No javacopts rmicopts secpropag

Options to pass to the java compiler.

Options to pass to the rmi compiler. true if the RMI Skel. and Stub. must be modified to implement the implicit propagation of the security context (the transactional context is always provided). If omitted, it defaults to false.

No

No

No verbose Indicates whether or not to use -verbose switch. If omitted, it defaults to false. additionalargs Add additional args to GenIC. keepgeneric true if the generic JAR file used as input to GenIC must be retained. If omitted, it defa ults to false. suffix String value appended to the JAR filename when creating each JAR. If omitted, it defaults to ".jar". orb nogenic

No

No

No

No

Choose your ORB : RMI, JEREMIE, DAVID. If omitted, it defaults to the one present in classpath. If specified, the corresponding JOnAS JAR is automatically added to the classpath.

If this attribute is set to true, JOnAS's GenIC will not be run on the EJB JAR.

Use this if you prefer to run GenIC at deployment time. If omitted, it defaults to false.

No

No

As noted above, the jonas element supports additional <classpath> nested elements.

Examples

This example shows ejbjar being used to generate deployment jars using a JOnAS EJB container. This example requires the naming standard to be used for the deployment descriptors. Using this format will create a EJB JAR file for each variation of '*-jar.xml' that is found in the deployment descriptor directory.

10.8 echoproperties

Description

Displays all the current properties in the project. The output can be sent to a file if desired.

You can also specify a subset of properties to save by naming a prefix: only properties starting with this prefix will be saved. This task can be used as a somewhat contrived means of returning data from an <ant> invocation, but is really for debugging build files.

Parameters

Attribute Description Required

No destfile If specified, the value indicates the name of the file to send the output of the statement to. The generated output file is compatible for loading by any Java application as a property file. If not specified, then the output will go to the Ant log. prefix a prefix which is used to filter the properties only those properties starting with this prefix will be echoed.

No failonerror By default, the "failonerror" attribute is enabled. If an error occurs while writing the properties to a file, and this attribute is enabled, then a BuildException will be thrown, causing the build to fail. If disabled, then IO errors will be reported as a log statement, and the build will continue without failure from this task.

Examples

<echoproperties/>

No

Report the current properties to the log.

<echoproperties destfile="my.properties"/>

10.9 FTP

Description

The ftp task implements a basic FTP client that can send, receive, list, delete files, and create directories. See below for descriptions and examples of how to perform each task.

Note: This task depends on external libraries not included in the Ant distribution. See

Library Dependencies for more information.

The ftp task makes no attempt to determine what file system syntax is required by the remote server, and defaults to Unix standards. remotedir must be specified in the exact syntax required by the ftp server. If the usual Unix conventions are not supported by the server, separator can be used to set the file separator that should be used instead.

See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task does not currently use the proxy information set by the <setproxy> task, and cannot go through a firewall via socks.

Warning: for the get and delete actions to work properly with a Windows 2000 ftp server, it needs to be configured to generate Unix style listings, and not the default MS-DOS listing.

Or someone needs to write the code to parse MS-DOS listings -any takers?

Parameters

Attribute

server port userid password remotedir

Description

the address of the remote ftp server. the port number of the remote ftp server. Defaults to port 21. the login id to use on the ftp server. the login password to use on the ftp server. the directory to which to upload files on the ftp server. action binary passive verbose the ftp action to perform, defaulting to "send". Currently supports

"put", "get", "del", "list", "chmod" and "mkdir".

No selects binary-mode ("yes") or text-mode ("no") transfers. Defaults to "yes" selects passive -mode ("yes") transfers. Defaults to "no"

No

No displays information on each file transferred if set to "yes". Defaults to "no".

No transfers only new or changed files if set to "yes". Defaults to "no". No depends newer separator umask chmod a synonym for depends. sets the file separator used on the ftp server. Defaults to "/". sets the default file permissions for new files, unix only. sets or changes file permissions for new or existing files, unix only.

If used with a put action, chmod will be issued for each file. listing the file to write results of the "list" action. Required for the "list" action, ignored otherwise. ignoreNoncriticalErrors flag which permits the task to ignore some non-fatal error codes

Ant Manual 1.5.4 12/9/2003 7:47 PM

sent by some servers during directory creation: wu-ftp in particular. Default: false skipFailedTransfers flag which enables unsuccessful file put, delete and get operations to No be skipped with a warning and the remainder of the files still transferred. Default: false

10.9.1 Sending Files

The easiest way to describe how to send files is with a couple of examples:

<ftp server="ftp.apache.org"

userid="anonymous"

password="[email protected]">

<fileset dir="htdocs/manual"/>

</ftp>

Logs in to ftp.apache.org as anonymous and uploads all files in the htdocs/manual directory to the default directory for that user.

<ftp server="ftp.apache.org"

remotedir="incoming"

userid="anonymous"

password="[email protected]"

depends="yes"

>

<fileset dir="htdocs/manual"/>

</ftp>

Logs in to ftp.apache.org as anonymous and uploads all new or changed files in the htdocs/manual

directory to the incoming directory relative to the default directory for anonymous

.

<ftp server="ftp.apache.org"

port="2121"

remotedir="/pub/incoming"

userid="coder"

password="java1"

depends="yes"

binary="no"

>

<fileset dir="htdocs/manual">

<include name="**/*.html"/>

</fileset>

</ftp>

Logs in to ftp.apache.org at port 2121 as coder with password java1 and uploads all new or changed HTML files in the htdocs/manual directory to the /pub/incoming directory. The files are transferred in text mode. Passive mode has been switched on to send files from behind a firewall.

<ftp server="ftp.nt.org"

remotedir="c:\uploads"

userid="coder"

209/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

password="java1"

separator="\"

verbose="yes"

>

<fileset dir="htdocs/manual">

<include name="**/*.html"/>

</fileset>

</ftp>

Logs in to the Windows-based ftp.nt.org as coder with password java1 and uploads all

HTML files in the htdocs/manual directory to the c:\uploads directory. Progress messages are displayed as each file is uploaded.

10.9.2 Getting Files

Getting files from an FTP server works pretty much the same way as sending them does.

The only difference is that the nested filesets use the remotedir attribute as the base directory for the files on the FTP server, and the dir attribute as the local directory to put the files into. The file structure from the FTP site is preserved on the local machine.

<ftp action="get"

server="ftp.apache.org"

userid="anonymous"

password="[email protected]">

<fileset dir="htdocs/manual">

<include name="**/*.html"/>

</fileset>

</ftp>

Logs in to ftp.apache.org as anonymous and recursively downloads all .html files from default directory for that user into the htdocs/manual directory on the local machine.

10.9.3 Deleting Files

As you've probably guessed by now, you use nested fileset elements to select the files to delete from the remote FTP server. Again, the filesets are relative to the remote directory, not a local directory. In fact, the dir attribute of the fileset is ignored completely.

<ftp action="del"

server="ftp.apache.org"

userid="anonymous"

password="[email protected]">

<fileset>

<include name="**/*.tmp"/>

</fileset>

</ftp>

Logs in to ftp.apache.org as anonymous and tries to delete all *.tmp files from the default directory for that user. If you don't have permission to delete a file, a BuildException is thrown.

10.9.4 Listing Files

<ftp action="list"

server="ftp.apache.org"

userid="anonymous"

210/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

password="[email protected]"

listing="data/ftp.listing">

<fileset>

<include name="**"/>

</fileset>

</ftp>

This provides a file listing in data/ftp.listing of all the files on the FTP server relative to the default directory of the anonymous user. The listing is in whatever format the FTP server normally lists files.

10.9.5 Creating Directories

Note that with the mkdir action, the directory to create is specified using the remotedir attribute.

<ftp action="mkdir"

server="ftp.apache.org"

userid="anonymous"

password="[email protected]"

remotedir="some/remote/dir"/>

This creates the directory some/remote/dir beneath the default root directory. As with all other actions, the directory separator character must be correct according to the desires of the FTP server.

10.10 icontract

Description

Instruments Java classes with iContract DBC preprocessor.

The task can generate a properties file for iContro l , a graphical user interface that lets you turn on/off assertions. iControl generates a control file that you can refer to from this task using the controlfile attribute.

Parameters

Attribute Description Required

srcdir Location of the java files. instrumentdir Indicates where the instrumented source files should go.

Yes

Yes repositorydir Indicates where the repository source files should go. builddir Indicates where the compiled instrumented classes should go.

Defaults to the value of instrumentdir. NOTE: Don't use the same directory for compiled instrumented classes and uninstrumented classes. It will break the dependency checking. (Classes will not be reinstrumented if you change them). repbuilddir Indicates where the compiled repository classes should go.

Defaults to the value of repositorydir. pre Indicates whether or not to instrument for preconditions. Defaults to true unless controlfile is specified, in which case it defaults to false. post Indicates whether or not to instrument for postconditions.

Defaults to true unless controlfile is specified, in which case it defaults to false.

Yes

No

No

No

No invariant Indicates whether or not to instrument for invariants. Defaults to true unless controlfile is specified, in which case it defaults to false.

No failthrowable The full name of the Throwable (Exception) that should be thrown No

211/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

when an assertion is violated. Defaults to java.lang.Error verbosity quiet

Indicates the verbosity level of iContract. Any combination of error*,warning*,note*,info*,progress*,debug* (comma separated) can be used. Defaults to error*

Indicates if iContract should be quiet. Turn it off if many your classes extend uninstrumented classes and you don't want warnings about this. Defaults to false

No

No updateicontrol If set to true, it indicates that the properties file for iControl in the current directory should be updated (or created if it doesn't exist).

Defaults to false.

No controlfile classdir targets

The name of the control file to pass to iContract. Consider using iControl to generate the file. Default is not to pass a file.

Name of the file that will be generated by this task, which lists all the classes that iContract will instrument. If specified, the file will not be deleted after execution. If not specified, a file will still be created, but it will be deleted after execution.

Only if updateicontrol=true

Indicates where compiled (unistrumented) classes are located.

This is required in order to properly update the icontrol.properties file, not for instrumentation.

Only if updateicontrol=true

No

Note: iContract will use the java compiler indicated by the project's build.compiler property. See documentation of the Javac task for more information. Nested includes and excludes are also supported.

Example:

Note: iContract will use the java compiler indicated by the project's build.compiler property. See documentation of the Javac task for more information.

Nested includes and excludes can be done very much the same way as any subclass of

10.15 JavaCC

Description

Invokes the JavaCC compiler compiler on a grammar file.

To use the javacc task, set the target attribute to the name of the grammar file to process.

You also need to specify the directory containing the JavaCC installation using the

218/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

javacchome attribute, so that ant can find the JavaCC classes. Optionally, you can also set the outputdirectory to write the generated file to a specific directory. Otherwise javacc writes the generated files to the directory containing the grammar file.

This task only invokes JavaCC if the grammar file is newer than the generated Java files. javacc assumes that the Java class name of the generated parser is the same as the name of the grammar file, ignoring the .jj. If this is not the case, the javacc task will still work, but it will always generate the output files.

Parameters

Attribute

target javacchome

Description

The grammar file to process.

The directory containing the JavaCC distribution.

Required

/>

This invokes JavaCC on grammar file src/Parser.jj, writing the generated files to build/src.

The grammar option STATIC is set to true when invoking JavaCC.

10.16 Javah

Description

Generates JNI headers from a Java class.

When this task executes, it will generate the C header and source files that are needed to implement native methods. JNI operates differently depending on whether JDK1.2

(or later) or pre-JDK1.2

systems are used.

Parameters

Attribute

class

Description

the fully-qualified name of the class (or classes, separated by commas)

Required

Yes outputFile destdir concatenates the resulting header or source files for all the classes listed into this file Yes sets the directory where javah saves the header files or the stub files. force old stubs verbose classpath specifies that output files should always be written (JDK1.2 only) specifies that old JDK1.0-style header files should be generated (otherwise output file contain JNI-style native method function prototypes) (JDK1.2 only) generate C declarations from the Java object file (used with old)

No

No

No causes Javah to print a message concerning the status of the generated files No the classpath to use. No

No

No bootclasspath location of bootstrap class files. extdirs location of installed extensions.

Either outputFile or destdir must be supplied, but not both.

Examples

<javah destdir="c" class="org.foo.bar.Wibble"/> makes a JNI header of the named class, using the JDK1.2 JNI model. Assuming the directory 'c' already exists, the file org_foo_bar_Wibble.h is created there. If this file already exists, it is left unchanged.

<javah outputFile="wibble.h">

<class name="org.foo.bar.Wibble,org.foo.bar.Bobble"/>

</javah> is similar to the previous example, except the output is written to a file called wibble.h in the current directory.

<javah destdir="c" force="yes">

220/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<class name="org.foo.bar.Wibble"/>

<class name="org.foo.bar.Bobble"/>

<class name="org.foo.bar.Tribble"/>

</javah> writes three header files, one for each of the classes named. Because the force option is set, these header files are always written when the Javah task is invoked, even if they already exist.

<javah destdir="c" verbose="yes" old="yes" force="yes">

<class name="org.foo.bar.Wibble"/>

<class name="org.foo.bar.Bobble"/>

<class name="org.foo.bar.Tribble"/>

</javah>

<javah destdir="c" verbose="yes" stubs="yes" old="yes" force="yes">

<class name="org.foo.bar.Wibble"/>

<class name="org.foo.bar.Bobble"/>

<class name="org.foo.bar.Tribble"/>

</javah> writes the headers for the three classes using the 'old' JNI format, then writes the corresponding .c stubs. The verbose option will cause Javah to describe its progress.

10.17 jspc

Description

Ant task to run the JSP compiler and turn JSP pages into Java source.

It can be used to precompile JSP pages for fast initial invocation of JSP pages, deployment on a server without the full JDK installed, or simply to syntax check the pages without deploying them. In most cases, a javac task is usually the next stage in the build process.

The task does basic dependency checking to prevent unnecessary recompilation -this checking compares source and destination timestamps, and does not factor in class or taglib dependencies, or <jsp:include> references.

By default the task uses the Jasper JSP compiler. This means the task needs jasper.jar and jasper-runtime.jar, which come with builds of Tomcat 4/Catalina from the Jakarta Tomcat project . We recommend Tomcat version 4.1.x for the most robust version of jasper.

There are many limitations with this task which partially stem from the many versions of

Jasper, others from implementation 'issues' in the task (i.e. nobody's willingness to radically change large bits of it to work around jasper). Because of this and the fact that JSP pages do not have to be portable across implementations -or versions of implementations- this task is better used for validating JSP pages before deployment, rather than precompiling them. For that, just deploy and run your httpunit junit tests after deployment to compile and test your pages, all in one go.

Parameters

The Task has the following attributes:

Attribute

destdir

Description

Where to place the generated files. They are located under here according to the given package name.

Required

Yes srcdir verbose

Where to look for source jsp files.

The verbosity integer to pass to the compiler. Default="0"

Yes

No

221/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

package compiler

Name of the destination package for generated java classes. No class name of a JSP compiler adapter, such as "jasper" or

"jasper41"

No -defaults to

"jasper" ieplugin mapped classpath

Java Plugin classid for Internet Explorer. No

(boolean) Generate separate write() calls for each HTML line in the JSP.

No

The classpath to use to run the jsp compiler. This can also be specified by the nested element classpath Path ).

A Reference . As per classpath

No, but it seems to work better when used

No classpathref failonerror uribase flag to control action on compile failures: default=yes No

The uri context of relative URI references in the JSP pages. If it does not exist then it is derived from the location of the file relative to the declared or derived value of uriroot.

No

The root directory that uri files should be resolved against. No uriroot compiler Class name of jsp compiler adapter to use. Defaults to the standard adapter for Jasper.

No compilerclasspath The classpath used to find the compiler adapter specified by the compiler attribute. webinc

No

Output file name for the fraction of web.xml that lists servlets. No webxml File name for web.xml to be generated No

The mapped option will, if set to true, split the JSP text content into a one line per call format. There are comments above and below the mapped write calls to localize where in the JSP file each line of text comes from. This can lead to a minor performance degradation

(but it is bound by a linear complexity). Without this options all adjacent writes are concatenated into a single write.

The ieplugin option is used by the <jsp:plugin> tags. If the Java Plug-in COM Class-ID you want to use changes then it can be specified here. This should not need to be altered. uriroot

specifies the root of the web application. This is where all absolute uris will be resolved from. If it is not specified then the first JSP page will be used to derive it. To derive it each parent directory of the first JSP page is searched for a WEB-INF directory, and the directory closest to the JSP page that has one will be used. If none can be found then the directory Jasperc was called from will be used. This only affects pages translated from an explicitly declared JSP file -including references to taglibs uribase is used to establish the uri context of relative URI references in the JSP pages. If it does not exist then it is derived from the location of the file relative to the declared or derived value of uriroot. This only affects pages translated from an explicitly declared JSP file.

Parameters specified as nested elements

This task is a directory based task , like javac, so the jsp files to be compiled are located as java files are by javac. That is, elements such as includes and excludes can be used directly inside the task declaration.

Elements specific to the jspc task are:-

classpath

222/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

The classpath used to compile the JSP pages, specified as for any other classpath.

classpathref

a reference to an existing classpath

webapp

Instructions to jasper to build an entire web application. The base directory must have a

WEB-INF subdirectory beneath it. When used, the task hands off all dependency checking to the compiler.

Attribute Description Required

basedir the base directory of the web application Yes

Example

<jspc srcdir="${basedir}/src/war"

destdir="${basedir}/gensrc"

package="com.i3sp.jsp"

compiler="jasper41"

verbose="9">

<include name="**/*.jsp" />

</jspc>

Build all jsp pages under src/war into the destination /gensrc, in a package heirarchy beginning with com.i3sp.jsp.

<jspc

destdir="interim"

verbose="1"

srcdir="src"

compiler="jasper41"

package="com.i3sp.jsp">

<include name="**/*.jsp" />

</jspc>

<depend

srcdir="interim"

destdir="build"

cache="build/dependencies"

classpath="lib/taglibs.jar"/>

<javac

srcdir="interim"

destdir="build"

classpath="lib/taglibs.jar"

debug="on"/>

Generate jsp pages then javac them down to bytecodes. Include lib/taglib jar in the java compilation. Dependency checking is used to scrub the java files if class dependencies indicate it is needed.

Notes

Using the package attribute it is possible to identify the resulting java files and thus do full dependency checking - this task should only rebuild java files if their jsp file has been modified. However, this only works with some versions of jasper. By default the checking supports tomcat 4.0.x with the "jasper" compiler, set the compiler to "jasper41" for the

223/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

tomcat4.1.x dependency checking. Even when it does work, changes in .TLD imports or in compile time includes do not get picked up.

Jasper generates JSP pages against the JSP1.2 specification -an implementation of version

2.3 of the servlet specification is needed to compile or run the java code.

10.18 JDepend

Description

Invokes the JDepend parser.

This parser "traverses a set of Java source file directories and generates design quality metrics for each Java package". It allows to "automatically measure the quality of a design in terms of its extensibility, reusability, and maintainability to effectively manage and control package dependencies."

Source file directories are defined by nested <sourcespath>, see nested elements .

Optionally, you can also set the outputfile name where the output is stored. By default the task writes its report to the standard output.

The task requires at least the JDepend 1.2 version.

Note: whereas the JDepend tool can be customized to exclude some packages, the current jdepend And Task does not have parameters to allow these exclusions. Read JDepend specific documentation for that purpose.

Parameters

Attribute Description Required

outputfile The output file name. If not set, the output is printed on the standard output. format fork

The format to write the output in. The default is "text", the alternative is

"xml"

Run the tests in a separate VM.

No

No haltonerror Stop the build process if an error occurs during the jdepend analysis. timeout jvm dir

No, default is "off"

No, default is "off"

No Cancel the operation if it doesn't finish in the given time (measured in milliseconds). (Ignored if fork is disabled.)

The command used to invoke the Java Virtual Machine, default is 'java'. The command is resolved by java.lang.Runtime.exec(). (Ignored if fork is

No, default

"java" disabled.)

The directory to invoke the VM in. (Ignored if fork is disabled) No classpathref the classpath to use, given as reference to a PATH defined elsewhere. No

Nested Elements

jdepend supports two nested elements <classpath> and <sourcespath>, that represent

PATH like structures .

<sourcespath>

is used to define the paths of the source code to analyze.

Examples

224/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<jdepend classpathref="base.path">

<sourcespath>

<pathelement location="src"/>

</sourcespath>

</jdepend>

This invokes JDepend on the src directory, writing the output on the standard output. The classpath is defined using a classpath reference.

<jdepend outputfile="docs/jdepend.xml" fork="yes" format="xml">

<sourcespath>

<pathelement location="src"/>

</sourcespath>

<classpath>

<pathelement location="classes"/>

<pathelement location="lib/jdepend.jar"/>

</classpath>

</jdepend>

This invokes JDepend in a separate VM on the src and testsrc directories, writing the output to the <docs/jdepend.xml> file in xml format. The classpath is defined using nested elements.

10.19 JJTree

Description

Invokes the JJTree preprocessor for the JavaCC compiler compiler. It inserts parse tree building actions at various places in the JavaCC source that it generates. The output of

JJTree is run through JavaCC to create the parser.

To use the jjtree task, set the target attribute to the name of the jjtree grammar file to process. You also need to specify the directory containing the JavaCC installation using the javacchome attribute, so that ant can find the JavaCC classes. Optionally, you can also set the outputdirectory to write the generated file to a specific directory. Otherwise jjtree writes the generated JavaCC grammar file to the directory containing the JJTree grammar file.

This task only invokes JJTree if the grammar file is newer than the generated JavaCC file.

Parameters

Attribute Description Required

target javacchome

The jjtree grammar file to process.

The directory containing the JavaCC distribution.

Yes

Yes outputdirectory The directory to write the generated file to. If not set, the files are written to the directory containing the grammar file. buildnodefiles Sets the BUILD_NODE_FILES grammar option. This is a boolean option.

No

No multi Sets the MULTI grammar option. This is a boolean option. No nodedefaultvoid Sets the NODE_DEFAULT_VOID grammar option. This is a boolean option. No nodefactory Sets the NODE_FACTORY grammar option. This is boolean option. No nodescopehook Sets the NODE_SCOPE_HOOK grammar option. This is a boolean option. No nodeusesparser Sets the NODE_USES_PARSER grammar option. This is a boolean option. No static visitor

Sets the STATIC grammar option. This is a boolean option.

Sets the VISITOR grammar option. This is a boolean option.

No

No

225/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

nodepackage Sets the NODE_PACKAGE grammar option. This is a string option. visitorexception Sets the VISITOR_EXCEPTION grammar option. This is a string option. nodeprefix Sets the NODE_PREFIX grammar option. This is a string option.

Example

<jjtree

target="src/Parser.jjt"

No

No

No

outputdirectory="build/src"

javacchome="c:/program files/JavaCC"

nodeusesparser="true"

/>

This invokes JJTree on grammar file src/Parser.jjt, writing the generated grammar file,

Parser.jj, file to build/src. The grammar option NODE_USES_PARSER is set to true when invoking JJTree.

10.20 Jlink - Deprecated

This task has been deprecated. Use the zipfileset and zipgroupfileset attributes of the Jar task or Zip task instead.

Description:

Links entries from sub-builds and libraries.

The jlink task can be used to build jar and zip files, similar to the jar task. However, jlink provides options for controlling the way entries from input files are added to the output file.

Specifically, capabilities for merging entries from multiple zip or jar files is available.

If a mergefile is specified directly (eg. at the top level of a mergefiles pathelement) and the mergefile ends in ".zip" or ".jar", entries in the mergefile will be merged into the outfile. A file with any other extension will be added to the output file, even if it is specified in the mergefiles element. Directories specified in either the mergefiles or addfiles element are added to the output file as you would expect: all files in subdirectories are recursively added to the output file with appropriate prefixes in the output file (without merging).

In the case where duplicate entries and/or files are found among the files to be merged or added, jlink merges or adds the first entry and ignores all subsequent entries. jlink ignores META-INF directories in mergefiles. Users should supply their own manifest information for the output file.

It is possible to refine the set of files that are being jlinked. This can be done with the includes, includesfile, excludes, excludesfile, and defaultexcludes attributes on the addfiles and mergefiles nested elements. With the includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whet her you want to use default exclusions or not. See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns. The patterns are relative to the base directory.

Parameters:

Attribute Description Required

226/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

outfile the path of the output file. Yes compress whether or not the output should be compressed. true, yes, or on result in compressed output. If omitted, output will be uncompressed

(inflated).

No mergefiles files to be merged into the output, if possible. addfiles files to be added to the output.

Examples

The following will merge the entries in mergefoo.jar and mergebar.jar into out.jar. mac.jar and pc.jar will be added as single entries to out.jar.

<jlink compress="false" outfile="out.jar">

At least one of mergefiles or addfiles

<mergefiles>

<pathelement path="${build.dir}/mergefoo.jar"/>

<pathelement path="${build.dir}/mergebar.jar"/>

</mergefiles>

<addfiles>

<pathelement path="${build.dir}/mac.jar"/>

<pathelement path="${build.dir}/pc.zip"/>

</addfiles>

</jlink>

Non-deprecated alternative to the above:

<jar compress="false" destfile="out.jar">

<zipgroupfileset dir="${build.dir}">

<include name="mergefoo.jar"/>

<include name="mergebar.jar"/>

</zipgroupfileset>

<fileset dir="${build.dir}">

<include name="mac.jar"/>

<include name="pc.jar"/>

</fileset>

</jar>

Suppose the file foo.jar contains two entries: bar.class and barnone/myClass.zip. Suppose the path for file foo.jar is build/tempbuild/foo.jar. The following example will provide the entry tempbuild/foo.jar in the out.jar.

<jlink compress="false" outfile="out.jar">

<mergefiles>

<pathelement path="build/tempbuild"/>

</mergefiles>

</jlink>

However, the next example would result in two top-level entries in out.jar, namely bar.class and barnone/myClass.zip

<jlink compress="false" outfile="out.jar">

<mergefiles>

<pathelement path="build/tempbuild/foo.jar"/>

</mergefiles>

</jlink>

Nested Elements

classpath

jpcoverage supports a nested <classpath> ele ment, that represents a PATH like structure .

jvmarg

Additional parameters may be passed to the VM via nested <jvmarg> attributes, for example:

<jpcoverage home="c:\jprobe" classname="MyClass">

<jvmarg value="-classic"/>

<classpath path="."/>

</jpcoverage> would run the coverage on "MyClass" in classic mode VM.

<jvmarg> allows all attributes described in Command line arguments .

Attribute Description Required

defaultexclude As a default, the coverage excludes all classes and methods.

Default filters are equivalent to

No, default to "true"

<filters>

<exclude class="*" method="*"/>

</filters>

As seen above, nested elements are include and exclude with a name attribute.

Attribute Description Required

class The class mask as a simple regular expression No, defaults to "*" method The method mask as a simple regular expression No, defaults to "*" enabled is the filter enabled? No, defaults to true

Example of filters

229/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<filters>

<include class="com.mycompany.*" method="*"/>

<exclude class="com.mycompany.MyClass" method="test*"/>

</filters> reports the coverage on all packages, classes and methods from com.mycompany except all methods starting by test on the class MyClass in the package com.mycompany

triggers

Define a number of events to use for interacting with the collection of data performed during coverage. For example you may run a whole application but only decide to collect data once it reaches a certain method and once it exits another one.

The only type of nested element is the method element (triggers are performed on method) and it has the following attributes:

Attribute Description Required

name event

The name of the method(s) as a regular expression. The name is the fully qualified name on the form package.classname.method

Yes the event on the method that will trigger the action. Must be "enter" or "exit". Yes action the action to execute. Must be one of "clear", "pause", "resume", "snapshot",

"suspend", or "exit".

<method name="ClassName.MethodName()" event="exit" action="exit"/>

</triggers>

Will take a snapshot when it enters any method of the class ClassName and will exit the program once it exits the method MethodName of the same class.

10.21.3 JPCovMerge

Description

Perform the merge of several snapshots into a single one.

Parameters

Attribute Description Required

home The directory where JProbe is installed. Yes tofile the output filename that will be the result of the name. Yes verbose Perform the merge in verbose mode giving details about the snapshot processing. jpcovmerge collects snapshots using the nested <FileSet> element.

Example of merge

No. Default to false

<fileset dir="./snapshots">

<include name="snap*.jpc"/>

</fileset>

230/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

</jpcovmerge> would run the merge in verbose mode on all snapshot files starting by snap in the directory snapshots. The resulting file will be named merge.jpc.

10.21.4 JPCovReport

Description

Generate a readable/printable report of a snapshot. Note that you will need Jakarta Oro in

Ant classpath, to run the reference feature.

Parameters

Attribute

home

Description

The directory where JProbe is intalled.

Required

Yes format type percent

The format of the generated report. Must be "xml", "html" or "text" No, default to

"html"

The type of report to be generated. Must be "executive",

"summary", "detailed" or "verydetailed"

A numeric value for the threshold for printing methods. Must be between 0 and 100.

No. Default to

"detailed"

No, default to 100

The name of the snapshot file that is the source to the report. Yes snapshot tofile The name of the generated output file includesource Include text of the source code lines. Only applies to format="xml" and type="verydetailed"

Yes

No. Defaults to

"yes"

sourcepath

Path to source files can be set via nested sourcepath elements that are PATH like structures .

reference (only applies to format="xml")

A reference is a set of classes whose coverage information will be checked against. Since

Coverage is only able to give you information about loaded classes, it will only report classes that were at least used in some points in your tests, therefore you will not be able to know what classes are not exercised at all during your tests. The reference is an additional feature that will analyze the bytecode of all classes in a given classpath that match some filters and modify the XML report accordingly. In short, it will:

• remove the classes that do not exists in the reference classpath. (For example you might have in your report some helper test classes that you do not want to appear in the report, but are unable to filter without adding hundred of filters for all your classes).

• add classes that exists in the reference set and match the filters but are not reported.

• remove abstract methods that are incorrectly reported in JProbe 3.0 (should be fixed in a later SP)

• remove classes/methods that do not match the filters.

classpath

Path to the reference set of files can be set via nested classpath elements that are PATH like structures .

filters

Nested elements are include and exclude with a class and method attribute.

Attribute Description Required

231/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

class The class mask as a simple regular expression No, default to * method The method mask as a simple regular expression No, default to *

Example of report

<jpcovreport home="c:\jprobe" snapshot="merge.jpc" format="xml" tofile="result.xml">

<sourcepath path="./src"/>

<reference>

<classpath path="./bin/classes"/>

<filters>

<include class="com.mycompany.*"/>

<exclude class="com.mycompany.MyClass" method="test*"/>

</filters>

</reference>

</jpcovreport> would generate the report of the file merge.jpc and write it to result.xml using the source path src. As well, it will modify the result.xml by analyzing all classes in the ./bin/classes that are port of the package com.mycompany except the method that start by test from the class MyClass.

Recommendation

If you generate your main code and your testcases in a separate directory, say bin/classes and test/classes. You should mostly end up with a reference such as:

<reference>

<classpath path="./bin/classes"/>

</reference>

With such a reference, your XML report will be cleaned up against parasite classes from your testcases (that as a common practice, generally match the exact package structure of the class you exercise).

HTML reports

You will find in Ant etc directory a stylesheet called coverage-frames.xsl. This file can be used to generate a framed report a la javadoc similar to the one for JUnit. It needs either

Xalan 1.2.2 or Xalan 2.x.

Xalan 1.2.2 (you must have xalan.jar and bsf.jar in your classpath)

<style processor="xalan" in="./reports/xml/results.xml" out="./reports/html/dummy.file"

style="${ant.home}/etc/coverage-frames.xsl">

<param name="output.dir" expression="'${basedir}/reports/html'"/>

</style>

Xalan 2.x (note the parameter without single quote)

<style processor="trax" in="./reports/xml/results.xml" out="./reports/html/dummy.file"

style="${ant.home}/etc/coverage-frames.xsl">

<param name="output.dir" expression="${basedir}/reports/html"/>

</style>

232/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

10.22 JUnit

Description

This task runs tests from the JUnit testing framework. The latest version of the framework can be found at http://www.junit.org

. This task has been tested with JUnit 3.0 up to JUnit

3.8.1; it won't work with versions prior to JUnit 3.0.

Note: This task depends on external libraries not included in the Ant distribution. See

Library Dependencies for more information.

Note: You must have junit.jar and the class files for the <junit> task in the same classpath.

You can do one of:

1. Put both junit.jar and the optional tasks jar file in ANT_HOME/lib.

2. Do not put either in ANT_HOME/lib, and instead include their locations in your

CLASSPATH environment variable.

3. Do neither of the above, and instead, specify their locations using a <classpath> element in the build file. See the FAQ for details.

Tests are defined by nested test or batchtest tags (see nested elements ).

Parameters

Attribute Description Required

printsummary fork haltonerror errorproperty haltonfailure filtertrace

Cancel the individual tests if they don&apos;t finish in the given time

(measured in milliseconds). Ignored if fork is disabled.

Send any output generated by tests to Ant's logging system as well as to the formatters. By default only the formatters receive the output.

No

233/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

By using the errorproperty and failureproperty attributes, it is possible to perform setup work (such as starting an external server), execute the test, clean up, and still fail the build in the event of a failure.

The filtertrace attribute condenses error and failure stack traces before reporting them. It works with both the plain and XML formatters. It filters out any lines that begin with the following string patterns:

"junit.framework.TestCase"

"junit.framework.TestResult"

"junit.framework.TestSuite"

"junit.framework.Assert."

"junit.swingui.TestRunner"

"junit.awtui.TestRunner"

"junit.textui.TestRunner"

"java.lang.reflect.Method.invoke("

"org.apache.tools.ant."

Nested Elements

The <junit> task supports a nested <classpath> element that represents a PATH like structure .

jvmarg

If fork is enabled, additional parameters may be passed to the new VM via nested

<jvmarg> elements. For example:

<junit fork="yes">

<jvmarg value="-Djava.compiler=NONE"/>

...

</junit> would run the test in a VM without JIT.

<jvmarg> allows all attributes described in Command-line Arguments .

sysproperty

Use nested <sysproperty> ele ments to specify system properties required by the class.

These properties will be made available to the VM during the execution of the test (either

ANT's VM or the forked VM, if fork is enabled). The attributes for this element are the same as for environment variables .

<junit fork="no">

<sysproperty key="basedir" value="${basedir}"/>

...

</junit> would run the test in ANT's VM and make the basedir property available to the test.

env

It is possible to specify environment variables to pass to the forked VM via nested <env> elements. For a description of the <env> element's attributes, see the description in the exec task.

Settings will be ignored if fork is disabled.

234/305

Ant Manual 1.5.4 12/9/2003 7:47 PM formatter

The results of the tests can be printed in different formats. Output will always be sent to a file, unless you set the usefile attribute to false. The name of the file is determined by the name of the test and can be set by the outfile attribute of <test>.

There are three predefined formatters - one prints the test results in XML format, the other emits plain text. The formatter named brief will only print detailed information for testcases that failed, while plain gives a little statistics line for all test cases. Custom formatters that need to implement org.apache.tools.ant.taskdefs.optional.junit.JUnitResultFormatter can be specified.

If you use the XML formatter, it may not include the same output that your tests have written as some characters are illegal in XML documents and will be dropped.

Attribute Description Required

type Use a predefined formatter (either xml, plain, or brief). classname Name of a custom formatter class. extension Extension to append to the output filename.

Exactly one of these.

Yes, if classname has been used. usefile Boolean that determines whether output should be sent to a file.

test

Defines a single test class.

Attribute

Define a number of tests based on pattern matching. batchtest collects the included files from any number of nested <fileset> s. It then generates a test class name for each file that ends in .java or .class.

Attribute Description Required

fork haltonerror

Run the tests in a separate VM. Overrides value set in <junit>. No

Stop the build process if an error occurs during the test run.

Overrides value set in <junit>.

No errorproperty The name of a property to set in the event of an error. Overrides No value set in <junit>. haltonfailure Stop the build process if a test fails (errors are considered failures as well). Overrides value set in <junit>. failureproperty The name of a property to set in the event of a failure (errors are considered failures as well). Overrides value set in <junit> filtertrace Filter out Junit and Ant stack frames from error and failure stack traces. Overrides value set in <junit>.

No

No

No; default is on. todir Directory to write the reports to. No; default is the current directory. if unless

Only run tests if the named property is set.

Only run tests if the named property is not set.

No

No

Batchtests can define their own formatters via nested <formatter> elements.

Examples

<junit>

<test name="my.test.TestCase"/>

</junit>

Runs the test defined in my.test.TestCase in the same VM. No output will be generated unless the test fails.

<junit printsummary="yes" fork="yes" haltonfailure="yes">

<formatter type="plain"/>

<test name="my.test.TestCase"/>

</junit>

Runs the test defined in my.test.TestCase in a separate VM. At the end of the test, a oneline summary will be printed. A detailed report of the test can be found in TESTmy.test.TestCase.txt

. The build process will be stopped if the test fails.

<junit printsummary="yes" haltonfailure="yes">

<classpath>

<pathelement location="${build.tests}"/>

<pathelement path="${java.class.path}"/>

</classpath>

<formatter type="plain"/>

<test name="my.test.TestCase" haltonfailure="no" outfile="result">

<formatter type="xml"/>

</test>

236/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<batchtest fork="yes" todir="${reports.tests}">

<fileset dir="${src.tests}">

<include name="**/*Test*.java"/>

<exclude name="**/AllTests.java"/>

</fileset>

</batchtest>

</junit>

Runs my.test.TestCase in the same VM, ignoring the given CLASSPATH; only a warning is printed if this test fails. In addition to the plain text test results, for this test a XML result will be output to result.xml. Then, for each matching file in the directory defined for

${src.tests} a test is run in a separate VM. If a test fails, the build process is aborted.

Results are collected in files named TEST-name.txt and written to ${reports.tests}.

10.23 JUnitReport

Merge the individual XML files generated by the JUnit task and eventually apply a stylesheet on the resulting merged document to provide a browsable report of the testcases results.

Note: This task depends on external libraries not included in the Ant distribution. See

Library Dependencies for more information.

Requirements

The task needs Xalan 2.x

; although Xalan 1.2.2

does work, but as Xalan1 is not supported, we do not recommend this.

If you do you use Xalan 1.2.2 you will need a compatible (older) version of Xerces. as well as BSF(bsf.jar). Again, using Xalan 2 is simpler and supported.

Parameters

Attribute Description Required

tofile The name of the XML file that will aggregate all individual XML testsuite previously generated by the JUnit task.

No. Default to TESTS-

TestSuites.xml todir The directory where should be written the file resulting from the individual XML testsuite aggregation.

No. Default to current directory

Nested Elements

fileset

junitreport collects individual xml files generated by the JUnit task using the nested

<FileSet> element.

report

Generate a browsable report based on the document created by the merge.

Parameters

Attribute Description Required

No, default to "frames" format The format of the generated report. Must be "noframes" or

"frames". styledir The directory where the stylesheets are defined. They must be conforming to the following conventions: frames format: the stylesheet must be named junit-frames.xsl. noframes format: the stylesheet must be named junitnoframes.xsl.

No. Default to embedded stylesheets.

237/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

todir The directory where the files resulting from the transformation should be written to.

Example of report

<junitreport todir="./reports">

<fileset dir="./reports">

<include name="TEST-*.xml"/>

</fileset>

<report format="frames" todir="./report/html"/>

No. Default to current directory

</junitreport> would generate a TESTS-TestSuites.xml file in the directory reports and generate the default framed report in the directory report/html.

10.24 MMetrics

Stephane Bailliez ( [email protected]

)

Requirements

This task requires Metamata Development environment 2.0/Webgain Quality Analyzer 2.0.

An evaluation version is available at Webgain . (Though you will not be able to use Metrics from the command line if you do not have a registered version). You also need a TRaX compliant processor(such as Xalan 2.x

) via JAXP 1.1

Description

Invokes the Metamata Metrics / WebGain Quality Analyzer source code analyzer on a set of

Java files. mmetrics will compute the metrics of a set of Java files and write the results to an XML file.

As a convenience, a stylesheet is given in etc directory, so that an HTML report can be generated from the XML file.

Parameters

Attribute Description Required

metamatahome The home directory containing the Metamata distribution. Yes tofile granularity

The XML were the resulting metrics will be written to.

Metrics granularity of the source files. Must be either files (compilationunits), types (types and compilation-units) or methods (methods, types and compilation-units).

Yes

Yes maxmemory Set the maximum memory for the JVM. this is a convenie nt way to set the

-mx or -Xmx argument.

No

Nested elements

For specifying the source code to analyze, you can either use a path or fileset elements

(though a single path element is preferred, see note below).

jvmarg

Additional parameters may be passed to the VM via nested <jvmarg> attributes. <jvmarg> allows all attributes described in Command line arguments .

classpath

238/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Sets class path (also source path unless one explicitly set). Overrides

METAPATH/CLASSPATH environment variables. The classpath element represents a PATH like structure .

sourcepath

Sets source path. Overrides the SOURCEPATH environment variable. The sourcepath element represents a PATH like structure .

path

Sets the list of directories to analyze the code for metrics.;It represents a PATH structure .

fileset

Sets a set of files to analyze for metrics.source It represents a FILESET structure .

Note: For the sake of readability, it is highly recommended to analyze for a single unique directory instead than using filesets or several directories. Otherwise there will be multiple metrics outputs without any way to know what metrics refers to what source. Chance are also that the XML handler that does some heuristic will be confused by the different outputs.

Example

<mmetrics tofile="mmetrics.xml"

metamatahome="c:/metamata"

granularity="methods">

<classpath>

<pathelement location="c:/metamata/examples/metricsexamples"/>

</classpath>

<sourcepath>

<pathelement location="c:/metamata/examples/metricsexamples"/>

</sourcepath>

<path>

<pathelement location="c:/metamata/examples/metricsexamples"/>

</path>

</mmetrics>

This invokes Metamata Metrics installed in c:/metamata on the metrics example. (Note that here, classpath and sourcepath are not normally not needed)

Generating a report

As a convenience, there is an XSL file(mmetrics-frames.xsl) that allows you to generate a full framed HTML report of the metrics. You can find it in the etc directory of Ant. As it uses the Xalan redirect extensions, you will need Xalan and Xerces to run it. The stylesheet takes an output.dir parameter (otherwise it will be generated in the current directory), it can be run in Ant as follows:

<style in=java "${metrics.xml}" style="mmetrics-frames.xsl" out="null.tmp">

<param name="output.dir" expression="${report.dir}"/>

</style>

No. Default to false.

Finds declarations unused in search paths. It will look for unused global No. Default to declarations in the source code within a use domain specified by the searchpath element. false. maxmemory Set the maximum memory for the JVM. this is a convenient way to set the -mx or -Xmx argument.

No

Nested elements

jvmarg

Additional parameters may be passed to the VM via nested <jvmarg> attributes. <jvmarg> allows all attributes described in Command line arguments .

You can avoid using the <jvmarg> by adding these empty entries to metamata.properties located at ${metamata.home}/bin metamata.classpath= metamata.sourcepath= metamata.baseclasspath=

classpath

Sets class path (also source path unless one explicitly set). Overrides

METAPATH/CLASSPATH environment variables. The classpath element represents a PATH like structure .

sourcepath

sourcepath

Sets the search path to use as the use domain when looking for unused global declarations.

The searchpath element represents a PATH like structure .

fileset

240/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Sets the Java files to audit via a FILESET structure. Whatever the filter is, only the files that ends with .java will be included for processing. Note that the base directory used for the fileset MUST be the root of the source files otherwise package names deduced from the file path will be incorrect.

Example

<maudit tofile="c:/metamata/examples/auditexamples/audit.xml"

metamatahome="c:/metamata" fix="yes">

<classpath>

<pathelement location="c:/metamata/examples/auditexamples"/>

</classpath>

<sourcepath>

<pathelement location="c:/metamata/examples/auditexamples"/>

</sourcepath>

<fileset dir="c:/metamata/examples/auditexamples">

<include name="*.java"/>

</fileset>

</maudit>

This invokes Metamata Audit installed in c:/metamata on the audit examples and fix automatically the fixable errors.

Generating a report

As a convenience, there is an XSL file(mmetrics-frames.xsl) that allows you to generate a full framed HTML report of the metrics. You can find it in the etc directory of Ant. As it uses the Xalan redirect extensions, you will need Xalan and Xerces to run it. The stylesheet takes an output.dir parameter (otherwise it will be generated in the current directory), it can be run in Ant as follows:

<style in=java "${audit.xml}" style="maudit-frames.xsl" out="null.tmp">

<param name="output.dir" expression="${report.dir}"/>

</style>

<pathelement location="c:/metamata/examples/"/>

</classpath>

</mparse>

This invokes Metamata MParse installed in c:/metamata on one of the grammar file example

(JavaParser.jj) and cleans up the intermediate Sun JavaCC file.

10.28

Description:

Native2Ascii

Converts files from native encodings to ASCII with escaped Unicode. A common usage is to convert source files maintained in a native operating system encoding, to ASCII prior to compilation.

Files in the directory src are converted from a native encoding to ASCII. By default, all files in the directory are converted. However, conversion may be limited to selected files using includes and excludes attributes. For more information on file matching patterns, see the section on directory based tasks . If no encoding is specified, the default encoding for the

JVM is used. If ext is specified, then output files are renamed to use it as a new extension.

More sophisticated file name translations can be achieved using a nested <mapper> element. By default an identity mapper will be used. If dest and src point to the same directory, the ext attribute or a nested <mapper> is required.

This task forms an implicit File Set , and supports all attributes of <fileset> (dir becomes src) as well as nested <include>, <exclude>, and <patternset> elements.

Attribute Description Required

243/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

reverse encoding src dest ext

Reverse the sense of the conversion, i.e. convert from ASCII to native

The native encoding the files are in (default is the default encoding for the

JVM)

The directory to find files in (default is basedir)

The directory to output file to

File extension to use in renaming output files

No

No

No

Yes

No

No includes includesfile excludes comma- or space-separated list of patterns of files that must be included.

All files are included when omitted. the name of a file. Each line of this file is taken to be an include pattern comma- or space-separated list of patterns of files that must be excluded.

No files (except default excludes) are excluded when omitted.

No

No

No excludesfile

Examples

the name of a file. Each line of this file is taken to be an exclude pattern

<native2ascii encoding="EUCJIS" src="srcdir" dest="srcdir"

No

includes="**/*.eucjis" ext=".java"/>

Converts all files in the directory srcdir ending in .eucjis from the EUCJIS encoding to ASCII and renames them to end in .java.

<native2ascii encoding="EUCJIS" src="native/japanese" dest="src"

includes="**/*.java"/>

Converts all the files ending in .java in the directory native/japanese to ASCII, placing the results in the directory src. The names of the files remain the same.

10.29 NetRexxC

Description

Compiles a NetRexx source tree within the running (Ant) VM.

The source and destination directory will be recursively scanned for NetRexx source files to compile. Only NetRexx files that have no corresponding class file or where the class file is older than the java file will be compiled.

Files in the source tree are copied to the destination directory, allowing support files to be located properly in the classpath. The source files are copied because the NetRexx compiler cannot produce class files in a specific directory via parameters

The directory structure of the source tree should follow the package hierarchy.

It is possible to refine the set of files that are being compiled/copied. This can be done with the includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes srcdir) as well as the nested <include>, <exclude> and <patternset> elements.

244/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

All properties except classpath, srcdir and destDir are also available as properties in the form ant.netrexxc.attributename, eg.

<property name="ant.netrexxc.verbose" value="noverbose"/> or from the command line as ant -Dant.netrexxc.verbose=noverbose ...

Ant Manual 1.5.4 12/9/2003 7:47 PM

Version 1.1 - 2001/01/09

10.30.1 Introduction

These tasks provide an interface to the Perforce SCM. The org.apache.tools.ant.taskdefs.optional.perforce package consists of a simple framework to support p4 functionality as well as some Ant tasks encapsulating frequently used (by me :-) p4 commands. However, the addition of new p4 commands is a pretty simple task (see the source). Although it is possible to use these commands on the desktop, they were primarily intended to be used by automated build systems.

Note: These tasks require the oro 2.0.XXX

regular expression package. Simply download this package and copy the jakarta-oro-2.0.XXX.jar file into Ant's lib directory. You will also need the Perforce client executable (p4 or p4.exe but not p4win.exe) in your path.

10.30.2 The Tasks

P4Sync Synchronise a workspace to a depot

P4Change Request a new changelist from the Perforce server

P4Edit Open files for edit (checkout)

P4Submit Submit a changelist to the Perforce server (checkin)

P4Have List current files in client view, useful for reporting

P4Label Create a label reflecting files in the current workspace

P4Counter Obtain or set the value of a counter

P4Reopen Move files between changelists

P4Revert Revert files

P4Add Add files

10.30.3 General P4 Properties

Each p4 task requires a number of settings, either through build-wide properties, individual attributes or environment variables. These are

Property Attribute Env Var Description Default

p4.port port p4.client client

P4PORT The p4d server and port to connect to

P4CLIENT The p4 client spec to use perforce:1666

The logged in username p4.user user P4USER The p4 username The logged in username

-- view -- The client, branch or label view to operate upon.

See the p4 user guide for more info.

//...

Your local installation of Perforce may require other settings (e.g. P4PASSWD, P4CONFIG).

At the moment, these can only be set outside of Ant, as environment variables.

Additionally, you may also specify the following attributes:

Attribute Description Required

failonerror Specifies whether to stop the build (true|yes|on) or keep going

(false|no|off) if an error is returned from the p4 command.

Examples

No; defaults to true.

Setting in the environment:-

(Unix csh) setenv P4PORT myperforcebox:1666

10.31.1 Introduction

Ant provides an optional task for editing property files. This is very useful when wanting to make unattended modifications to configuration files for application servers and applications. Currently, the task maintains a working property file with the ability to add properties or make changes to existing ones. However, any comments are lost.

10.31.2 PropertyFile Task

Parameters

Attribute Description Required

file Location of the property file to be edited Yes comment Header for the file itself no

Parameters specified as nested elements

Entry

Use nested <entry> elements to specify actual modifications to the property file itself.

Attribute Description Required

key Name of the property name/value pair Yes value Value to set (=), to add (+) or subtract (-) default Initial value to set for a property if it is not already defined in the

At least one must be specified

252/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

type property file.

For type date, an additional keyword is allowed: "now"

Regard the value as : int, date or string (default) operation "+" or "=" (default) for all datatypes

"-" (for date and int only).

No

No pattern For int and date type only. If present, Values will be parsed and formatted accordingly.

No unit The unit of the value to be applied to date +/- operations. Valid

Values are: millisecond second minute hour day (default) week month year

This only applies to date types using a +/- operation.

No

The rules used when setting a property value are shown below. The operation occurs after these rules are considered.

• If only value is specified, the property is set to it regardless of its previous value.

• If only default is specified and the property previously existed in the property file, it is unchanged.

If only default is specified and the property did not exist in the property file, the property is set to default.

If value and default are both specified and the property previously existed in the property file, the property is set to value.

If value and default are both specified and the property did not exist in the property file, the property is set to default.

Examples

The following changes the my.properties file. Assume my.properties look like:

# A comment akey=novalue

After running, the file would now look like

#Thu Nov 02 23:41:47 EST 2000 akey=avalue adate=2000/11/02 23\:41 anint=1 formated.int=0014 formated.date=028 17\:34

The slashes conform to the expectations of the Properties class. The file will be stored in a manner so that each character is examined and escaped if necessary. Note that the original comment is now lost. Please keep this in mind when running this task against heavily commented properties files. It may be best to have a commented version in the source tree,

253/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

copy it to a deployment area, and then run the modifications on the copy. Future versions of

PropertyFile will hopefully eliminate this shortcoming.

<propertyfile

file="my.properties"

comment"My properties">

<entry key="akey" value="avalue"/>

<entry key="adate" type="date" value="now"/>

<entry key="anint" type="int" operation="+"/>

<entry key="formated.int" type="int" default="0013" operation="+" pattern="0000"/>

<entry key="formated.date" type="date" value="now" pattern="DDD HH:mm"/>

</propertyfile>

To produce dates relative from today :

<propertyfile

file="my.properties"

comment="My properties">

<entry key="formated.date-1"

type="date" default="now" pattern="DDD"

operation="-" value="1"/>

<entry key="formated.tomorrow"

type="date" default="now" pattern="DDD"

operation="+" value="1"/>

</propertyfile>

Concatenation of strings :

<propertyfile

file="my.properties"

comment="My properties">

<entry key="progress" default="" operation="+" value="."/>

</propertyfile>

Each time called, a "." will be appended to "progress"

10.32 Ant Pvcs Task User Manual

Note: Before using this task, the user running ant must have access to the commands of

PVCS (get and pcli) and must have access to the repository. Note that the way to specify the repository is platform dependent so use property to specify location of repository. by

Thomas Christensen ( [email protected]

)

Don Jeffery ( [email protected]

)

Version 1.1 - 2001/06/27

Problems with UNC pathnames and the use of () in paths are fixed and an updateonly argument introduced.

Version 1.0 - 2001/01/31

Initial release.

254/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

10.32.1 Introduction

The pvcs task allows the user of ant to extract the latest edition of the source code from a

PVCS repository. PVCS is a version control system developed by Merant .

This version has been tested agains PVCS version 6.5 and 6.6 under Windows and Solaris.

10.32.2 Pvcs Task

Description

The pvcs task is set to point at a PVCS repository and optionally a project within that repository, and can from that specification get the latest version of the files contained by the repository.

Parameters

Attribute Description Required

repository pvcsproject label

The location of the repository (see your PVCS manuals)

The project within the PVCS repository to extract files from ("/" is root project and that is default if this attribute isn't specified)

Only files marked with this label are extracted.

Yes

No

No promotiongroup Only files within this promotion group are extracted. Using both the label and the promotiongroup tag will cause the files in the promotion group and with that label to be extracted.

No force If set to yes all files that exists and are writable are overwritten. Default no causes the files that are writable to be ignored. This stops the PVCS command get to stop asking questions!

No workspace By specifying a workspace, the files are extracted to that location. A PVCS workspace is a name for a location of the workfiles and isn't as such the location itself. You define the location for a workspace using the PVCS GUI clients. If this isn't specified the default workspace for the current user is used.

No pvcsbin On some systems the PVCS executables pcli and get are not found in the

PATH. In such cases this attribute should be set to the bin directory of the

PVCS installation containing the executables mentioned before. If this attribute isn't specified the tag expects the executables to be found using the PATH environment variable.

No ignorereturncode If set to true the return value from executing the pvcs commands are updateonly ignored.

If set to true files are gotten only if newer than existing local files.

No

No filenameformat The format of your folder names in a format suitable for java.text.MessageFormat. Defaults to {0}-arc({1}). Repositories where the archive extension is not -arc should set this.

No linestart Used to parse the output of the pcli command. It defaults to "P:. The parser already knows about / and \\, this property is useful in cases where the repository is accessed on a Windows platform via a drive letter mapping.

No

Nested Elements

pvcsproject element

pvcs supports a nested <pvcsproject> element, that represents a project within the PVCS repository to extract files from. By nesting multiple <pvcsproject> elements under the

<pvcs> task, multiple projects can be specified.

Parameters

255/305

10.33 RenameExtensions – Deprecated

This task has been deprecated. Use the move task with a glob mapper instead.

Description

Renames files in the srcDir directory ending with the fromExtension string so that they end with the toExtension string. Files are only replaced if replace is true.

See the section on directory based tasks , on how the inclusion/exclusion of files works, and how to write patterns. This task forms an implicit FileSet and supports all attributes of

<fileset> (dir becomes srcDir) as well as the nested <include>, <exclude> and

<patternset> elements.

Parameters

Attribute Description Required

No defaultexcludes indicates whether default excludes should be used or not ("yes"/"no").

Default excludes are used when omitted. excludes excludesfile comma- or space-separated list of patterns of files that must be excluded.

No files (except default excludes) are excluded when omitted. the name of a file. Each line of this file is taken to be an exclude pattern fromExtention The string that files must end in to be renamed

No

No

Yes

No includes includesfile replace srcDir comma- or space-separated list of patterns of files that must be included.

All files are included when omitted. the name of a file. Each line of this file is taken to be an include pattern

Whether the file being renamed to should be replaced if it already exists

The starting directory for files to search in toExtension The string that renamed files will end with on completion

Examples

<renameext srcDir="/source/project1" includes="**" excludes="**/samples/*" fromExtension=".java.keep" toExtension=".java" replace="true"/>

No

No

Yes

Yes

Ant Manual 1.5.4 12/9/2003 7:47 PM

10.34 ReplaceRegExp

Description

ReplaceRegExp is a directory based task for replacing the occurrence of a given regular expression with a substitution pattern in a selected file or set of files.

The output file is only written if it differs from the existing file. This prevents spurious rebuilds based on unchanged files which have been regenerated by this task.

Similar to regexp type mappers this task needs a supporting regular expression library and an implementation of org.apache.tools.ant.util.regexp.Regexp. Ant comes with implementations for the java.util.regex package of JDK 1.4

, jakarta-regexp and jakarta-

ORO , but you will still need the library itself.

There are cross-platform issues for matches related to line terminator. For example if you use $ to anchor your regular expression on the end of a line the results might be very different depending on both your platform and the regular expression library you use. It is

'highly recommended' that you test your pattern on both Unix and Windows platforms before you rely on it.

Jakarta Oro defines a line terminator as '\n' and is consistent with Perl.

Jakarta RegExp uses a system-dependant line terminator.

JDK 1.4 uses '\n', '\r\n', '\u0085', '\u2028', '\u2029' as a default but is configured in the wrapper to use only '\n' (UNIX_LINE)

We strongly recommend that you use Jakarta Oro.

Parameters

Attribute Description Required

file match file for which the regular expression should be replaced.

The regular expression pattern to match in the file(s)

Yes if no nested

<fileset> is used

Yes, if no nested

<regexp> is used replace flags

The substitution pattern to place in the file(s) in place of the regular expression.

Yes, if no nested

<substitution> is used

The flags to use when matching the regular expression. For more information, consult the Perl5 syntax g : Global replacement. Replace all occurences found i : Case Insensitive. Do not consider case in the match m : Multiline. Treat the string as multiple lines of input, using "^" and

"$" as the start or end of any line, respectively, rather than start or end of string. s : Singleline. Treat the string as a single line of input, using "." to match any character, including a newline, which normally, it would not match.

No byline Process the file(s) one line at a time, executing the replacement on one line at a time (true/false). This is useful if you want to only replace the first occurence of a regular expression on each line, which is not easy to do when processing the file as a whole. Defaults to false.

No

Examples

<replaceregexp file="${src}/build.properties"

match="OldProperty=(.*)"

replace="NewProperty=\1"

258/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

byline="true"/> replaces occurrences of the property name "OldProperty" with "NewProperty" in a properties file, preserving the existing value, in the file ${src}/build.properties

Parameters specified as nested elements

This task supports a nested FileSet element.

This task supports a nested Regexp element to specify the regular expression. You can use this element to refer to a previously defined regular expression datatype instance.

<regexp id="id" pattern="expression"/>

<regexp refid="id"/>

This task supports a nested Substitution element to specify the substitution pattern. You can use this element to refer to a previously defined substitution pattern datatype instance.

<substitution id="id" pattern="expression"/>

<substitution refid="id"/>

Examples

<replaceregexp byline="true">

<regexp pattern="OldProperty=(.*)"/>

<substitution expression="NewProperty=\1"/>

<fileset dir=".">

<includes="*.properties"/>

</fileset>

</replaceregexp> replaces occurrences of the property name "OldProperty" with "NewProperty" in a properties file, preserving the existing value, in all files ending in .properties in the current directory

<replaceregexp match="\s+" replace=" " flags="g" byline="true">

<fileset dir="${html.dir}" includes="**/*.html" />

</replaceregexp> replaces all whitespaces (blanks, tabs, etc) by one blank remaining the line separator. So with input

<html> <body>

<<TAB>><h1> T E S T </h1> <<TAB>>

<<TAB>> </body></html> would converted to

<html> <body>

<h1> T E S T </h1> </body></html>

10.36.1 ServerDeploy element

Description:

The serverdeploy task is used to run a "hot" deployment tool for vendor-specific J2EE server. The task requires nested elements which define the attributes of the vendor-specific deployment tool being executed. Vendor-specific deployment tools elements may enforce rules for which attributes are required, depending on the tool.

Parameters:

Attribute Description Required

action This is the action to be performed. For most cases this will be "deploy".

Some tools support additional actions, such as "delete", "list", "undeploy",

"update"...

Yes source A fully qualified path/filename of the component to be deployed.

This may be an .ear, .jar, .war, or any other type that is supported by the server.

Tool dependant

Nested Elements

The serverdeploy task supports a nested classpath element to set the classpath.

<setproxy socksproxyhost="socksy"/> use socks via socksy:1080

<setproxy socksproxyhost=""/> stop using the socks server

Parameters

Attribute Description Type

nonProxyHosts A list of hosts to bypass the proxy on. These should be separated with the vertical bar character '|'.

Only in Java 1.4 does ftp use this list. e.g. fozbot.corp.sun.com|*.eng.sun.com.

String proxyHost the HTTP/ftp proxy host. Set this to "" for the http proxy option to be disabled String proxyPort the HTTP/ftp proxy port number; default is 80 int

263/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

socksProxyHost The name of a Socks server. Set to "" to turn socks proxying off. String socksProxyPort Set the ProxyPort for socks connections. The default value is 1080

10.38 Script

Description

Execute a script in a BSF supported language. int

Note: This task depends on external libraries not included in the Ant distribution. See

Library Dependencies for more information.

All items (tasks, targets, etc) of the running project are accessible from the script, using either their name or id attributes (as long as their names are considered valid Java identifiers, that is). The name "project" is a pre-defined reference to the Project, which can be used instead of the project name.

BeanShell users: This task now natively supports the BeanShell scripting language, using language="beanshell". The BeanShell engine is still required.

Scripts can do almost anything a task written in Java could do.

Parameters

Attribute Description

language The programming language the script is written in. Must be a supported BSF language src The location of the script as a file, if not inline

Examples

<project name="squares" default="main" basedir=".">

BUILD SUCCESSFUL

10.39

Description

Sound

Plays a sound-file at the end of the build, according to whether the build failed or succeeded. You can specify either a specific sound-file to play, or, if a directory is specified, the <sound> task will randomly select a file to play. Note: At this point, the random selection is based on all the files in the directory, not just those ending in appropriate suffixes for sound-files, so be sure you only have sound-files in the directory you specify.

Unless you are running on Java 1.3 or later, you need the Java Media Framework on the classpath (javax.sound).

Nested Elements

success

Specifies the sound to be played if the build succeeded.

265/305

Ant Manual 1.5.4 12/9/2003 7:47 PM fail

Specifies the sound to be played if the build failed.

Nested Element Parameters

The following attributes may be used on the <success> and <fail> elements:

Attribute Description

source the path to a sound-file directory, or the name of a specific sound-file, to be played. loops the number of extra times to play the sound-file; default is 0. duration the amount of time (in milliseconds) to play the sound-file.

Examples

<target name="fun" if="fun" unless="fun.done">

<sound>

<success source="${user.home}/sounds/bell.wav"/>

<fail source="${user.home}/sounds/ohno.wav" loops="2"/>

</sound>

<property name="fun.done" value="true"/>

</target>

Required

Yes

No

No plays the bell.wav sound-file if the build succeeded, or the ohno.wav sound-file if the build failed, three times, if the fun property is set to true. If the target is a dependency of an

"initialization" target that other targets depend on, the fun.done property prevents the target from being executed more than once.

<target name="fun" if="fun" unless="fun.done">

<sound>

<success source="//intranet/sounds/success"/>

<fail source="//intranet/sounds/failure"/>

</sound>

<property name="fun.done" value="true"/>

</target> randomly selects a sound-file to play when the build succeeds or fails.

10.40 SourceOffSite Tasks User Manual

by Jesse Stockall

Version 1.1 2002/01/23

10.40.1 Introduction

These tasks provide an interface to the Microsoft Visual SourceSafe SCM via SourceGear's

SourceOffSite product. SourceOffSite is an add-on to Microsoft's VSS, that allows remote development teams and tele-commuters that need fast and secure read/write access to a centralized SourceSafe database via any TCP/IP connection. SOS provides Linux ,Solaris &

Windows clients. The org.apache.tools.ant.taskdefs.optional.sos package consists of a simple framework to support SOS functionality as well as some Ant tasks encapsulating frequently used SOS commands. Although it is possible to use these commands on the desktop, they were primarily intended to be used by automated build systems. These tasks have been tested with SourceOffSite version 3.5.1 connecting to VisualSourceSafe 6.0. The tasks have been tested with Linux, Solaris & Windows2000.

No 5000 ms

269/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Deprecated properties

The following properties can be used to configure the proxy settings to retrieve an image from behind a firewall. However, the settings apply not just to this task, but to all following tasks. Therefore they are now mostly deprecated in preference to the <setproxy> task, that makes it clear to readers of the build exactly what is going on. We say mostly as this task's support includes proxy authentication, so you may still need to use its proxy attributes. useproxy Use a proxy to access imgurl. Note: Only tested on JDK 1.2.2 and above No None proxy IP or hostname of the proxy server No None port Proxy portnumber user User to authenticate to the proxy as. password Proxy password

Examples

<splash/>

No None

No None

No None

Splash images/ant_logo_large.gif from the classpath.

<splash imageurl="http://jakarta.apache.org/images/jakarta-logo.gif"

useproxy="true"

showduration="5000"/>

Splashes the jakarta logo, for an initial period of 5 seconds.

10.42 StarTeam Support

• STCheckout

• STCheckin

• STLabel

• STList

StarTeam (deprecated)

These tasks make use of functions from the StarTeam API. As a result they are only available to licensed users of StarTeam. You must have starteam-sdk.jar in your classpath to run these tasks. For more information about the StarTeam API and how to license it, see the Borland web site.

Important Note on Installation and Licensing:

On Windows machines, the mere presence of starteam-sdk.jar on the classpath is

not sufficient for getting these tasks to work properly. These tasks also require a fully-installed and fully-licensed version of the StarGate Runtime. This is part of a StarTeam client installation or may be installed separately. The full client install is not required. In particular, the Windows path must include the directory where the StarGate Runtime .dll files are installed.

Earlier versions of Ant (prior to 1.5.2) did not have this restriction because they were not as dependent on the StarTeam runtime - which the newer versions use to access StarTeam file status information. The older versions lacked this important capability.

270/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

10.42.1 Common Parameters for All Starteam Tasks

The following parameters, having to do with making the connection to a StarTeam project, are common to all the following tasks except the deprecated StarTeam task.

Attribute Description Required

yes username The username of the account used to log in to the StarTeam server. password The password of the account used to log in to the StarTeam server.

URL A string o f the form servername:portnum/project/view which enables user to set all of these elements in one string. yes

Either this ... servername The name of the StarTeam server. serverport The port number of the StarTeam server. projectname The name of the StarTeam project on which to operate. viewname The name of the view in the StarTeam project on which to operate.

... or all four of these must be defined.

10.42.2 STCheckout

Description

Checks out files from a StarTeam project.

The includes and excludes attributes function differently from other tasks in Ant.

Inclusion/exclusion by folder is NOT supported.

Parameters

See also the required common StarTeam parameters .

Attribute Description Required

rootstarteamfolder The root of the subtree in the StarTeam repository from which to check out files. Defaults to the root folder of the view ('/'). rootlocalfolder The local folder which will be the root of the tree to which files are checked out. If this is not supplied, then the StarTeam

"default folder" associated with rootstarteamfolder is used. createworkingdirs creates local folders even when the corresponding StarTeam folder is empty. Defaults to "true". no no no deleteuncontrolled if true, any files NOT in StarTeam will be deleted. Defaults to

"true". includes Only check out files that match at least one of the patterns in this list. Patterns must be separated by commas. Patterns in excludes take precedence over patterns in includes. no no excludes Do not check out files that match at least one of the patterns in this list. Patterns must be separated by commas. Patterns in excludes take precedence over patterns in includes. no label recursive forced locked

Check out files as of this label. The label must exist in starteam or an exception will be thrown. If not specified, the most recent version of each file will be checked out.

Indicates if subfolders should be searched for files to check out.

Defaults to "true". no no

If true, checkouts will occur regardless of the status that

StarTeam is maintaining for the file. If rootlocalfolder is set then this should be set "true" as otherwise the checkout will be based on statuses which do not relate to the target folder. Defaults to

"false". no

If true, file will be locked against changes by other users. If false

(default) has no effect.

Either or neither, but not

271/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

unlocked If true, file will be unlocked so that other users may change it.

This is a way to reverse changes that have not yet been checked in. If false (default) has no effect.

Examples

<stcheckout servername="STARTEAM"

serverport="49201" both, may be true.

projectname="AProject"

viewname="AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

force="true"

/>

The minimum necessary to check out files out from a StarTeam server. This will check out all files in the AView view of the AProject project to C:\dev\buildtest\co. Empty folders in

StarTeam will have local folders created for them and any non-StarTeam files found in the tree will be deleted.

<stcheckout URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

forced="true"

/>

And this is a simpler way of accomplishing the same thing as the previous example, using the URL attribute.

<stcheckout URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

rootstarteamfolder="\Dev"

excludes="*.bak *.old"

label="v2.6.001"

forced="true"

/>

This will check out all files from the Dev folder and below that do not end in .bak or .old with the label v2.6.001.

<stcheckout URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

includes="*.htm,*.html"

excludes="index.*"

forced="true"

/>

This is an example of overlapping includes and excludes attributes. Because excludes takes precedence over includes, files named index.html will not be checked out by this command.

272/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<stcheckout URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

includes="*.htm,*.html"

excludes="index.*"

forced="true"

recursive="false"

/>

This example is like the previous one, but will only check out files in C:\dev\buildtest\co, because of the turning off of the recursive attribute.

<stcheckout URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootstarteamfolder="src/java"

rootlocalfolder="C:\dev\buildtest\co"

forced="true"

/>

<stcheckout URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootstarteamfolder="src/java"

/>

<stcheckout URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootstarteamfolder="src/java"

rootlocalfolder="C:\dev\buildtest\co\src\java"

forced="true"

/>

In the preceding three examples, assuming that the AProject project has a default folder of

"C:\work\AProject", the first example will check out the tree of files rooted in the src/java folder of the AView view of the AProject in the StarTeam repository to a local tree rooted at

C:\dev\buildtest\co, the second to a tree rooted at C:\work\AProject\src \java (since no rootlocalfolder is specified) and the third to a tree rooted at C:\dev\buildtest\co\src \java.

Note also, that since the second example does not set "forced" true, only those files which the repository considers out-of-date will be checked out.

10.42.3 STCheckin

Description

Checks files into a StarTeam project. Optionally adds files and in the local tree that are not managed by the repository to its control.

The includes and excludes attributes function differently from other tasks in Ant.

Inclusion/exclusion by folder is NOT supported.

Parameters

See also the required common StarTeam parameters .

Attribute Description Required

rootstarteamfolder The root of the subtree in the StarTeam repository into which to files will be checked. Defaults to the root folder of the view ('/'). no rootlocalfolder The local folder which will be the root of the tree to which files are checked out. If this is not supplied, then the StarTeam "default folder" no

273/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

associated with rootstarteamfolder is used. comment includes

Checkin comment to be saved with the file. adduncontrolled if true, any files or folders NOT in StarTeam will be added to the repository. Defaults to "false".

Only check in files that match at least one of the patterns in this list.

Patterns must be separated by commas. Patterns in excludes take precedence over patterns in includes. excludes Do not check in files that match at least one of the patterns in this list.

Patterns must be separated by commas. Patterns in excludes take precedence over patterns in includes. recursive Indicates if subfolders should be searched for files to check in. Defaults to "false". forced unlocked

If true, checkins will occur regardless of the status that StarTeam is maintaining for the file. If rootlocalfolder is set then this should be set

"true" as otherwise the checkin will be based on statuses which do not relate to the target folder. Defaults to "false".

If true, file will be unlocked so that other users may change it. If false

(default) lock status will not change.

Examples

<stcheckin servername="STARTEAM"

serverport="49201"

projectname="AProject"

viewname="AView" no no no no no no no

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

forced="true"

/>

The minimum necessary to check files into a StarTeam server. This will check all files on the local tree rooted at C:\dev\buildtest\co into the AView view of the AProject project in the repository. For files and folders in the local tree but not in starteam, nothing will be done.

Since the forced attribute is set, the files which are checked in will be checked in without regard to what the StarTeam repository considers their status to be. This is a reasonable choice of attributes since StarTeam's status for a file is calculated based on the local file in the StarTeam default directory, not on the directory we are actually working with.

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

forced="true"

/>

And this is a simpler way of giving the same commands as the command above using the

URL shortcut.

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

rootstarteamfolder="\Dev"

excludes="*.bak *.old"

274/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

forced="true"

/>

This will check all files in to the Dev folder and below that do not end in .bak or .old from the tree rooted at"C:\dev\buildtest\co" .

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

includes="*.htm,*.html"

excludes="index.*"

forced="true"

/>

This is an example of overlapping includes and excludes attributes. Because excludes takes precedence over includes, files named index.html will not be checked in by this command.

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

rootstarteamfolder="src/java"

includes="*.htm,*.html"

excludes="index.*"

forced="true"

recursive="false"

/>

This example is like the previous one, but will only check in files from C:\dev\buildtest\co, because of the turning off of the recursive attribute.

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

rootstarteamfolder="src/java"

includes="version.txt"

forced="true"

recursive="false"

/>

This example is like the previous one, but will only check only in one file,

C:\dev\buildtest\co\version.txt to the StarTeam folder src/java.

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootlocalfolder="C:\dev\buildtest\co"

rootstarteamfolder="src/java"

includes="version.java"

forced="true"

recursive="false"

addUncontrolled="true"

275/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

comment="Fix Bug #667"

/>

This example is like the previous one, but will only check only in one file,

C:\dev\buildtest\co\version.java to the StarTeam folder src/java. Because the

addUncontrolled attribute has been set, if StarTeam does not already control this file in this location, it will be added to the repository. Also, it will write a comment to the repository for this version of the file.

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootstarteamfolder="src/java"

rootlocalfolder="C:\dev\buildtest\co"

forced="true"

/>

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootstarteamfolder="src/java"

/>

<stcheckin URL="STARTEAM:49201/Aproject/AView"

username="auser"

password="secret"

rootstarteamfolder="src/java"

rootlocalfolder="C:\dev\buildtest\co\src\java"

forced="true"

/>

In the preceding three examples, assuming that the AProject project has a default folder of

C:\work\buildtest\co\AProject, the first example will check in files from a tree rooted at

C:\dev\buildtest\co, the second from a tree rooted at

C:\work\buildtest\co\AProject\src \java, and the third from a tree rooted at

C:\dev\buildtest\co\src \java all to a tree rooted at src/java

10.42.4 STLabel

Description

Creates a view label in StarTeam at the specified view. The label will be classified by

StarTeam as a "build label". This task will fail if there already exexists in viewname a label with the same name as the label parameter.

Parameters

See also the required common StarTeam parameters .

Attribute Description Required

label The name to be given to the label lastbuild The timestamp of the build that will be stored with the label. Must be formatted yyyyMMddHHmmss description A description of the label to be stored in the StarTeam project. yes yes no

Examples

This example shows the use of this tag. It will create a label named Version 6.2 with

"Thorough description" as its description.

276/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<tstamp>

label="Version 6.2"

lastbuild="${nowstamp}"

description="Thorough description"

/>

10.42.5 STList

Description

Produces a listing of the contents of the StarTeam repository at the specified view and

StarTeamFolder. The listing will contain the name of the user, if any, who has the file locked, the size of the file, its lastModifiedDate in the repository, and the name of the file.

Unless the rootLocalFolder is specified, listing will also show the status of the local file in the default local directory relative to the repository.

Parameters

See also the required common StarTeam parameters .

Attribute Description Required

rootstarteamfolder The root of the subtree in the StarTeam repository to be listed. Defaults to the root folder of the view ('/'). no rootlocalfolder The local folder which will be the root of the tree to which files are compared. If this is not supplied, then the StarTeam "default folder" associated with rootstarteamfolder is used and a status field will appear in the listing. Otherwise, the status field will not appear. no includes Only list files that match at least one of the patterns in this list. Patterns must be separated by commas. Patterns in excludes take precedence over patterns in includes. no no excludes label

Do not list files that match at least one of the patterns in this list.

Patterns must be separated by commas. Patterns in excludes take precedence over patterns in includes.

List files, dates, and statuses as of this label. The label must exist in starteam or an exception will be thrown. If not specified, the most recent version of each file will be listed. recursive Indicates if subfolders should be searched for files to list. Defaults to

"true".

Examples

<stlist url="WASHINGTON:49201/build"

username="auser" no no

password="secret"

/>

The above command might produce the following listing:

[stlist] Folder: Build (Default folder: C:/work/build)

10.42.6 Starteam - Deprecated

This task has been deprecated. Use the STCheckout task instead.

Description

Checks out files from a StarTeam project.

The includes and excludes attributes function differently from other tasks in Ant. Multiple patterns must be separated by spaces, not commas. See the examples for more information.

Parameters

Attribute Description Required

username password

The username of the account used to log in to the StarTeam server. yes

The password of the account used to log in to the StarTeam server. yes servername serverport projectname viewname targetfolder

The name of the view in the StarTeam project. yes

The folder to which files are checked out. What this precisely means is determined by the targetFolderAbsolute param. yes targetFolderAbsolute Determines how targetfolder is interpreted, that is, whether the

StarTeam "default folder" for the project is factored in (false) or whether targetFolder is a complete mapping to foldername (true). If

"true", the target tree will be rooted at targetfolder+"default folder". If false, the target tree will be rooted at targetfolder. Defaults to "false". no foldername force

The subfolder in the project from which to check out files.

Overwrite existing folders if this is set to "true". Defaults to "false". no no recursion

The name of the StarTeam server.

The port number of the StarTeam server.

The name of the StarTeam project. yes yes yes verbose includes

Indicates if subfolders should be searched for files to check out.

Defaults to "true". no

Provides progress information. Defaults to "false". no

Only check out files that match at least one of the patterns in this list. no

278/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

excludes

Patterns must be separated by spaces. Patterns in excludes take precedence over patterns in includes.

Do not check out files that match at least one of the patterns in this list. Patterns must be separated by spaces. Patterns in excludes take precedence over patterns in includes.

Examples

<starteam servername="STARTEAM"

serverport="49201"

projectname="AProject"

viewname="AView"

username="auser"

password="secret"

targetfolder="C:\dev\buildtest\co"

/> no

The minimum necessary to check out files out from a StarTeam server. This will check out all files in the AView view of the AProject project to C:\dev\buildtest\co.

<starteam servername="STARTEAM"

serverport="49201"

projectname="AProject"

viewname="AView"

username="auser"

password="secret"

targetfolder="C:\dev\buildtest\co"

foldername="\Dev"

excludes="*.bak *.old"

force="true"

/>

This will checkout all files from the Dev folder and below that do not end in .bak or .old. The force flag will cause any existing files to be overwritten by the version in StarTeam.

<starteam servername="STARTEAM"

serverport="49201"

projectname="AProject"

viewname="AView"

username="auser"

password="secret"

targetfolder="C:\dev\buildtest\co"

includes="*.htm *.html"

excludes="index.*"

/>

This is an example of overlapping includes and excludes attributes. Because excludes takes precedence over includes, files named index.html will not be checked out by this command.

<starteam servername="STARTEAM"

serverport="49201"

projectname="AProject"

foldername="src/java"

viewname="AView"

279/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

username="auser"

password="secret"

targetfolder="C:\dev\buildtest\co"

targetfolderabsolute="true"

/>

<starteam servername="STARTEAM"

serverport="49201"

projectname="AProject"

foldername="src/java"

viewname="AView"

username="auser"

password="secret"

targetfolder="C:\dev\buildtest\co"

targetfolderabsolute ="false"

/>

<starteam servername="STARTEAM"

serverport="49201"

projectname="AProject"

foldername="src/java"

viewname="AView"

username="auser"

password="secret"

targetfolder="C:\dev\buildtest\co\src\java"

targetfolderabsolute="true"

/>

In the preceding three examples, assuming that the AProject project has a default folder of

"AProject", the first example will check the files located in starteam under src/java out to a tree rooted at C:\dev\buildtest\co, the second to a tree rooted at

C:\dev\buildtest\co\AProject\src \java and the third to a tree rooted at

C:\dev\buildtest\co\src \java.

10.43 Stylebook

Description

This executes the apache Stylebook documentation generator. Unlike the commandline version of this tool, all three arguments are required to run stylebook.

Note: This task depends on external libraries not included in the Ant distribution. See

Library Dependencies for more information.

Being extended from <Java>, all the parent's attributes and options are available. Do not set any apart from the classpath as they are not guaranteed to be there in future.

Parameters

Attribute Description Required

book the book xml file that the documentation generation starts from Yes skindirectory the directory that contains the stylebook skin Yes targetdirectory the destination directory where the documentation is generated Yes

The user can also specify the nested <classpath> element which defines classpath in which the task is executed.

280/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Examples

<stylebook targetdirectory="build/docs"

book="src/xdocs/book.xml"

skindirectory="src/skins/myskin"/>

The above will generate documentation in build/docs starting from the book src/xdocs/book.xml and using the skin located in directory src/skins/myskin.

10.44 Telnet

Description

Task to automate a remote telnet session. The task uses nested <read> to indicate strings to wait for, and <write> tags to specify text to send.

If you do specify a userid and password, the system will assume a common unix prompt to wait on. This behavior can be easily over-ridden.

Note: This task depends on external libraries not included in the Ant distribution. See

Library Dependencies for more information.

Parameters

Attribute Values Required

userid server port the login id to use on the telnet server. password the login password to use on the telnet server.

Only if password is specified

Only if userid is specified the address of the remote telnet server. Yes the port number of the remote telnet server. Defaults to port 23. No initialCR send a cr after connecting ("yes"). Defaults to "no". No

No

Nested Elements

The commands to send to the server, and responses to wait for, are described as nested elements.

read

declare (as a text child of this element) a string to wait for. The element supports the timeout attribute, which overrides any timeout specified for the task as a whole. It also has a string attribute, which is an alternative to specifying the string as a text element.

Always declare an opening and closing <read> element to ensure that statements are not sent before the connection is ready, and that the connection is not broken before the final command has completed. write

describes the text to send to the server. The echo boolean attribute controls whether the string is echoed to the local log; this is "true" by default

Examples

A simple example of connecting to a server and running a command. This assumes a prompt of "ogin:" for the userid, and a prompt of "assword:" for the password.

281/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

<telnet userid="bob" password="badpass" server="localhost">

<read>/home/bob</read>

<write>ls</write>

<read string="/home/bob"/>

</telnet>

This task can be rewritten as:

<telnet server="localhost">

<read>ogin:</read>

<write>bob</write>

<read>assword:</read>

<write>badpass</write>

<read>/home/bob</read>

<write>ls</write>

<read>/home/bob</read>

</telnet>

A timeout can be specified at the <telnet> level or at the <read> level. This will connect, issue a sleep command that is suppressed from displaying and wait 10 seconds before quitting.

<telnet userid="bob" password="badpass" server="localhost" timeout="20">

<read>/home/bob</read>

<write echo="false">sleep 15</write>

<read timeout="10">/home/bob</read>

</telnet>

The task can be used with other ports as well:

<telnet port="80" server="localhost" timeout="20">

<read/>

<write>GET / http/0.9</write>

<write/>

<read timeout="10">&lt;/HTML&gt;</read>

</telnet>

To use this task against the WinNT telnet service, you need to configure the service to use classic authentication rather than NTLM negotiated authentication. This can be done in the

Telnet Server Admin app: select "display/change registry settings", then "NTLM", then set the value of NTLM to 1.

10.45 Test

Description

This is a primitive task to execute a unit test in the org.apache.testlet framework.

This task is deprectated as the Testlet framework has been abandoned in favor of

JUnit by the Avalon community.

Note: This task depends on external libraries not included in the Ant distribution. See

Library Dependencies for more information.

Parameters

282/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Attribute Description

showSuccess a boolean value indicating whether tests should display a message on success

Required

No showBanner a boolean value indicating whether a banner should be displayed when starting testlet engine forceShowTrace a boolean indicating that a stack trace is displayed on any failure

No

No showTrace a boolean indicating that a stack trace is displayed on error (but not normal failure)

No

The user can also specify the nested <classpath> element which defines classpath in which the task is executed. The user also specifies a subele ment per testlet executed which has content that specifies tasklet classname.

Examples

<test showSuccess="false" showBanner="false" showTrace="true" forceShowTrace="true">

<classpath refid="test.classpath"/>

<testlet>org.foo.MyTestlet</testlet>

<testlet>org.foo.MyOtherTestlet</testlet>

</test>

The above will run the testlets org.foo.MyTestlet and org.foo.MyOtherTestlet

10.46 Translate

Description

Identifies keys in files delimited by special tokens and translates them with values read from resource bundles.

A resource bundle contains locale-specific key-value pairs. A resource bundle is a hierarchical set of property files. A bundle name makes up its base family name. Each file that makes up this bundle has this name plus its locale. For example, if the resource bundle name is MyResources, the file that contains German text will take the name

MyResources_de. In addition to language, country and variant are also used to form the files in the bundle.

The resource bundle lookup searches for resource files with various suffixes on the basis of

(1) the desired locale and (2) the default locale (basebundlename), in the following order from lower-level (more specific) to parent-level (less specific): basebundlename + "_" + language1 + "_" + country1 + "_" + variant1 basebundlename + "_" + language1 + "_" + country1 basebundlename + "_" + language1 basebundlename basebundlename + "_" + language2 + "_" + country2 + "_" + variant2 basebundlename + "_" + language2 + "_" + country2 basebundlename + "_" + language2

The file names generated thus are appended with the string ".properties" to make up the file names that are to be used.

File encoding is supported. The encoding scheme of the source files, destination files and the bundle files can be specified. Destination files can be exlicitly overwritten using the

forceoverwrite attribute. If forceoverwrite is false, the destination file is overwritten only if

283/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

either the source file or any of the files that make up the bundle have been modified after the destination file was last modified.

FileSet s are used to select files to translate.

Parameters

Attribute

todir starttoken endtoken

Description

Destination directory where destination files are to be created.

The starting token to identify keys.

The ending token to identify keys. bundle Family name of resource bundle. bundlelanguage Locale specific language of resource bundle. Defaults to default locale's language. bundlecountry Locale specific country of resource bundle. Defaults to default locale's country.

Required

Yes

Yes

Yes

Yes

No

No bundlevariant Locale specific variant of resource bundle. Defaults to the default variant of the country and language being used.

No srcencoding Source file encoding scheme. Defaults to system default file encoding. destencoding Destination file encoding scheme. Defaults to source file encoding. bundleencoding Resource Bundle file encoding scheme. Defaults to source file encoding.

No

No

No forceoverwrite Overwrite existing files even if the destination files are newer. Defaults to

"no".

No

Parameters specified as nested elements

fileset

FileSets are used to select files that contain keys for which value translated files are to be generated.

Examples

Translate source file encoded in english into its japanese equivalent using a resource bundle encoded in japanese.

<translate toDir="$(dest.dir}/ja"

starttoken="#"

endtoken="#"

bundle="resource/BaseResource"

bundlelanguage="ja"

forceoverwrite="yes"

srcencoding="ISO8859_1"

destencoding="SJIS"

bundleencoding="SJIS">

<fileset dir="${src.dir}">

<include name="**/*.jsp"/>

</fileset>

</translate>

History

10.47.2 Introduction

Visual Age for Java is a great Java IDE, but it lacks decent build support; for creating deliveries. On the other hand, Ant supports the build process very good, but is (at least at the moment) command line based. So we decided to write some tasks to access the VAJ repository and a small visual Ant frontend to make running Ant from VAJ possible. We use the Tool API to integrate Ant in VisualAge for Java. In combination with the VAJ tasks

(vajload, vajexport, vajimport) you can load defined versions of projects into your workspace, export the source code, compile it with an external compiler and build a jar without leaving the IDE. Of course compile messages are viewed in a logging window.

Concluding: This tool provides decent deployment support VAJ has not (out of the box).

What's new

2003/01/16 Now works outside of VAJ.

Added attribute haltonerror, "*" and "**" version qualifiers.

Amended documentation (this file) accordingly.

2001/06/14 Now all tasks can access VAJ via 'Remote Access To Tool API'.

Therefore builds containing VAJ tasks can also be executed from the command line (Kudos to Glenn McAllister for describing the concept and providing source code at http://www7.software.ibm.com/vad.nsf/Data/Document4366 .

It is possible to cancel a running build executed from the plugin

Improved error handling in the plugin. Now all errors should show up either in the log window or in the console.

10.47.3 The Tasks

At the moment there are three tasks which help integrating the VAJ repository contents into an external build process:

VAJLoad loads specified versions into the workspace

VAJExport exports specified packages into the file system

VAJImport imports specified files into the workspace

These tasks are described in detail below.

285/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

10.47.4 VAJLoad

Description:

Loads a specified VAJ project version into the workspace.

Parameters

Attribute Description Required

remote name and port of a remote tool server. (format: <servername>:<port no>).

If this attribute is set, the tasks will be executed on the specified tool server. no haltonerror Stop the build process if an error occurs, (default: "yes") no

Parameters specified as nested elements

vajproject

Attribute Description Required

name name of the VAJ project to load into the workspace yes version name of the requested version, or one of the special qualifiers "*" or "**"

"*" loads the latest versioned edition of the project yes

"**" will load the latest version (including open editions)

Example

<vajload remote="localhost:32767">

<vajproject name="My App" version="*"/>

<vajproject name="My Testcases" version="**"/>

<vajproject name="JUnit" version="3.2"/>

</vajload>

10.47.5 VAJExport

Description:

Exports Java source files, class files and/or resources from the workspace to the file system.

Exports can be specified by giving the VAJ project name and package name(s). This works very similar to FileSets .

Parameters

Attribute Description Required

destdir location to store the exported files yes exportSources export source files (default: "yes") exportResources export resource files (default: "yes") exportClasses export class files (default: "no") exportDebugInfo include debug info in exported class files (default: "no") defaultexcludes use default excludes when exporting (default: "yes").

Default excludes are: IBM*/**, Java class libraries/**, Sun class libraries*/**, JSP Page Compile Generated Code/**, VisualAge*/** overwrite remote overwrite existing files (default: "yes") name and port of a remote tool server. (format: <servername>:<port no>).

If this attribute is set, the tasks will be executed on the specified tool server. haltonerror Stop the build process if an error occurs, (default: "yes")

Parameters specified as nested elements

no no no no no no no no

286/305

Ant Manual 1.5.4 12/9/2003 7:47 PM include

specifies the packages to include into the export

Attribute Description Required

name name of the VAJ project and package to export.

The first element of the name must be the project name, then the package name elements separated by '/'. yes

exclude

specifies the packages to exclude from the export

Attribute Description Required

name name of the VAJ project/package not to export yes

Example

<vajexport destdir="${src.dir}" exportResources="no">

<include name="MyProject/**"/>

<exclude name="MyProject/test/**"/>

</vajexport>

This example exports all packages in the VAJ project 'MyProject', except packages starting with 'test'.

Default Excludes

The default excludes are:

IBM*/**

Java class libraries/**

Sun class libraries*/**

JSP Page Compile Generated Code/**

VisualAge*/**

10.47.6 VAJImport

Description:

Imports Java source files, class files and/or resources from the file system into VAJ. These imports can be specified with a fileset.

Parameters

Attribute Description Required

project imported files are added to this VAJ project importSources import source files (default: "yes") importResources import resource files (default: "yes") importClasses import class files (default: "no") remote name and port of a remote tool server. (format: <servername>:<port no>).

If this attribute is set, the tasks will be executed on the specified tool server. haltonerror Stop the build process if an error occurs, (default: "yes")

Parameters specified as nested elements

fileset

A FileSet specifies the files to import. yes no no no no no

287/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Example

<vajimport project="Test" importClasses="true">

<fileset dir="${import.dir}">

<include name="com/sample/**/*.class"/>

<exclude name="com/sample/test/**"/>

</fileset>

</vajimport>

This example imports all class files in the directory ${import.dir}/com/sample excluding those in the subdirectory test

10.47.7 The Plugin

The tasks are usable within VAJ by running the org.apache.tools.ant.Main class, but this is quite inconvenient. Therefore a small GUI is provided which allows selecting a build file and executing its targets. This Plugin is accessible from the VAJ Tools menu (see Usage ).

Installation

We assume C:\IBMVJava as VAJ install directory. If You have installed it elsewhere, adapt the pathes below.

Plugin

• Create the directory C:\IBMVJava\ide\tools\org-apache-tools-ant.

• Expand in that directory all the jars contained in the lib directory of your Ant installation.

• copy default.ini (in org\apache\tools\ant\taskdefs\optional\ide) to

C:\IBMVJava\ide\tools\org-apache-tools-ant\default.ini.

• if you want to access this help from the Workbench, create the directory

C:\IBMVJava\ide\tools\org-apache-tools-ant\doc and copy the files VAJAntTool.html, toolmenu.gif and anttool1.gif to it.

• VAJ has to be restarted to recognize the new tool.

• Now if You open the context menu of a project, You should see the entry 'Ant Build' in the Tools submenu (see Usage ).

• Make sure the tool works as expected.

Servlets for Remote Tool Access

• For a good introduction into the VAJ Remote Tool Access see the great introduction from Glenn McAllister at http://www7.software.ibm.com/vad.nsf/Data/Document4366 . It is highly recommended to read this article before doing the installation (to understand what you do :-) ).

• insert the following lines into C:\IBMVJava\ide\tools\com-ibm-ivjtoolserver\servlets\servlet.properties

. Typically this file is empty. If not, be careful not to delete the other lines. servlet.vajload.code=org.apache.tools.ant.taskdefs.optional.i de.VAJLoadServlet servlet.vajexport.code=org.apache.tools.ant.taskdefs.optional.ide.VAJExportServlet servlet.vajimport.code=org.apache.tools.ant.taskdefs.optional.ide.VAJImportServletName

• Expand the Ant libraries (ant.jar and optional.jar contained in the lib directory of your Ant installation) to the directory C:\IBMVJava\ide\tools\com-ibm-ivjtoolserver\servlets\

.

288/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

• configure the Remote Access (via Window- >Options..., then choose 'Remote Access

To Tool API') as shown in the following picture:

Now you should be able to execute VAJ Tasks from the command line.

Usage

Plugin

When the tool is installed correctly and your Ant build file is configured, it is really easy to use.

289/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Go to your Workbench, select the project you want to deploy and open its context menu. In the submenu Tools you should find the new entry Ant Build. Klick it to start the tool!

After a short time this frame should pop up:

This frame contains the following elements:

A menubar with some options described later

• The name of your selected VAJ project

• An entry field for the Ant XML buildfile with a browse [...] button. The full qualified filename, including the directory is needed here.

• A list with tasks specified in the buildfile. Until your first save of the build info

(described later), this list will be empty. When loading a build file by the (

Re)Load button, this list is filled with all tasks which have a description attribute.

The task you select in this list will be executed when pressing the Execute button.

• A pulldown box for specifying the log level.

• Four buttons. Two of them I have already described. The other are the Stop button to cancel a running build and the third one is just the Close button to exit our small tool!

290/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

• Note that the build is canceled on the next console output after pressing the Stop button, not directly after pressing it.

After you have set up your buildprocess you might find it useful to save the data you've just entered, so we implemented an option to save it to the repository into your selected project. Make sure that you have an open edition of your project before selecting Save

BuildInfo To Repository from the File menu. Now your information is saved to this edition of your project and will be loaded automatically the next time you start Ant Build.

If you have closed the log window accidentally, it can be reopened with the Log item in the

File menu, and if you want to know who developed this, just select About in the Help menu.

Servlets for Remote Tool Access

With the servlets installed and the remote access running you can use Ant from the command line without any restrictions. Just make sure the remote attribute in your build file is set correctly.

10.47.8 Frequently Asked Questions

Q: If I try to load a build file, I get the error "Can't load default task list". Why?

A: Ant not only contains class files, but also resource files. This messsage appears if the file

.../org/apache/tools/ant/taskdefs/defaults.properties is missing. Make sure that you import/export not only java/class files, but also all resource files when importing/exporting

Ant.

Q: If I try to re-load a build file, I get the error "XML parser factory has not been

configured correctly". Why?

A: Make sure the META-INF/services directory of the xercesImpl.jar has also been expanded into the C:\IBMVJava\ide\tools\org-apache-tools-ant directory.

Q: I want to load, export and build more then one Visual Age project to one jar!

How to?

A: The VA tasks are able to load and export several Projects all at once. You can choose whatever project you like for storing the tool information, it doesn't really matter

Q: When I load my build file, the list of targets is empty. Why?

A: You need to add the optional "description" parameter to the targets you want to come up in the list. Then reload the build file in the "ant build" tool. We chose to display only targets with description to allow the build file developer to distinguish between targets for end users and helper targets.

Q: Is there a sample build file available?

A: Now you can find an example in this manual

Q: Why does it export my entire workspace when I've already implicitly selected a

project when starting the Tool?

A: This selection does not carry into the buildfile you are using. Set the Project name at the beginning of the "includes" parameter.

Q: When I import Ant into my Workspace, I get Problems reported. Can I ignore

them?

291/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

A: It depends on the problems reported, and what you want to do with Ant. Problems you can't ignore:

• Classes from javax.xml.parser missing - install a compatible parser (see installation )

• Classes from com.ibm.ivj.util missing - install the Visual Age IDE Utility feature (see installation ).

• Errors in optional tasks you use within your build file

Q: I want to use the same buildfile both within Visual Age and from the command

line using my regular Ant environment. What do I need to be aware of?

A: You have to specifie a remote server via the 'remote' attribute. Otherwise the three

Visual Age tasks won't work when executing Ant from the command line.

Q: I can export packages from project 'ABC', but not from project 'XYZ'! Why?

A: Common reasons are:

The project is excluded by the default excludes (see attribute 'defaultexcludes' of

VAJExport)

• When looking at the project in the workspace, it is often difficult to distinguish between project name and version name (e.g. as in 'My GUI Components Java 2 3.5'). Check if you have the right project name by switching off the version name display temporarilly.

Q: How do I control the import/export of sourcefiles, compiled files and project

resources explicity?

A: Via the Boolean values exportClasses (default false) exportSources (default true) and exportResources (default true). In some situations, Resources are not exported correctly without this being explicity set. VAJ doesn't export resources correctly if a package contains only resources (see below).

Known Problems

Exporting a package containing just resources doesn't work. This is a VAJ Tool API bug.

Workaround: create a dummy class and set 'exportSources' to false.

VisualAge for Java Versions

This tool integration has been tested with versions 3.02 and 3.5 of VisualAge for Java. It should run with the 2.x Versions, too, but we didn't try. The graphical user interface is built with AWT so it is JDK independent by now.

10.48.1 Introduction

These tasks provide an interface to the Microsoft Visual SourceSafe SCM. The org.apache.tools.ant.taskdefs.optional.vss package consists of a simple framework to support vss functionality as well as some Ant tasks encapsulating frequently used vss commands. Although it is possible to use these commands on the desktop, they were primarily intended to be used by automated build systems.

If you get a CreateProcesss IOError=2 when running these, it means that ss.exe was not found. Check to see if you can run it from the command line -you may need to alter your path, or set the ssdir property.

10.48.2 The Tasks

vssget Retrieves a copy of the specified VSS file(s). vsslabel Assigns a label to the specified version or current version of a file or project. vsshistory Shows the history of a file or project in VSS. vsscheckin Updates VSS with changes made to a checked out file, and unlocks the VSS master copy.

vsscheckout Copies a file from the current project to the current fo lder, for the purpose of editing. vssadd vsscp

Adds a new file into the VSS Archive

Change the current project being used in VSS vsscreate Creates a project in VSS.

10.48.3 VssGet

Description

Task to perform GET commands to Microsoft Visual SourceSafe.

If you specify two or more attributes from version, date and label only one will be used in the order version, date, label.

Parameters

Attribute Values Required

vsspath login localpath ssdir

SourceSafe path which specifies the project/file(s) you wish to perform the action on. You should not specify the leading dollar-sign - it is prepended by Ant automatically. directory where ss.exe resides. By default the task expects it to be in the

PATH.

Yes username[,password] - The username and password needed to get access to VSS. Note that you may need to specify both (if you have a password)

- Ant/VSS will hang if you leave the password out and VSS does not

No accept login without a password.

Override the working directory and get to the specified path No

No serverPath directory where ss.ini resides. writable true or false<; default false/td>

No

No

Ant Manual 1.5.4 12/9/2003 7:47 PM

recursive version date label quiet true or false; default false. Note however that in the SourceSafe UI , there is a setting accessed via Tools/Options/GeneralTab called "Act on projects recursively". If this setting is checked, then the recursive attribute is effectively ignored, and the get will always be done recursively

No a version number to get a date stamp to get at

No, only one of these allowed a label to get for suppress output (off by default) No

No

Note that only one of version, date or label should be specified

Examples

<vssget localPath="C:\mysrc\myproject"

recursive="true"

label="Release1"

login="me,mypassword"

vsspath="/source/aProject"

writable="true"/>

Does a get on the VSS-Project $/source/myproject using the username me and the password mypassword. It will recursively get the files which are labeled Release1 and write them to the local directory C:\mysrc \myproject. The local files will be writable.

10.48.4 VssLabel

10.49 wljspc

Description

Class to precompile JSP's using weblogic's jsp compiler (weblogic.jspc)

Tested only on Weblogic 4.5.1 - NT4.0 and Solaris 5.7,5.8

Parameters

Attribute Values

No

Required

src dest oot of source tree for JSP, ie, the document root for your weblogic server root of destination directory, what you have set as WorkingDir in the weblogic properties package start package name under which your JSP's would be compiled classpath Class path to use when compiling jsp's

Yes

Yes

Yes

Yes

A classpath should be set which contains the weblogic classes as well as all application classes referenced by the JSP. The system classpath is also appended when the jspc is called, so you may choose to put everything in the classpath while calling Ant. However, since presumably the JSP's will reference classes being build by Ant, it would be better to explicitly add the classpath in the task.

The task checks timestamps on the JSP's and the generated classes, and compiles only those files that have changed.

It follows the weblogic naming convention of putting classes in

_dirName/_fileName.class for dirname/fileName.jsp

Example

<target name="jspcompile" depends="compile">

<wljspc src="c:\\weblogic\\myserver\\public_html" dest="c:\\weblogic\\myserver\\serverclasses" package="myapp.jsp">

<classpath>

<pathelement location="${weblogic.classpath}"/>

<pathelement path="${compile.dest}"/>

</classpath>

</wljspc>

</target>

Limitations

• This works only on weblogic 4.5.1

• It compiles the files thru the Classic compiler only.

• Since it is my experience that weblogic jspc throws out of memory error on being given too many files at one go, it is called multiple times with one jsp file each.

10.50 XMLValidate

Description

This task checks xml files are valid (or only well formed). The task uses the SAX2 parser implementation provided by JAXP by default (probably the one that is used by Ant itself), but one can specify any SAX1/2 parser if needed.

This task supports the use of nested xmlcatalog elements and/or nested <dtd> elements which are used to resolve DTDs and entities.

Parameters

Attribute Description

file the file(s) you want to check. (optionally can use an embedded fileset)

Required

No

No lenient if true, only check the xml document is well formed (ignored if the specified parser is as SAX1 parser) classname the parser to use. classpathref where to find the parser class. Optionally can use an embedded classpath element. failonerror fails on a error if set to true (defaults to true). warn log parser warn events.

Nested Elements

dtd

<dtd> is used to specify different locations for DTD resolution.

Attribute Description

publicId Public ID of the DTD to resolve location Location of the DTD to use, which can be a file, a resource, or a URL

xmlcatalog

The xmlcatalog element is used to perform Entity resolution.

Examples

Ant Manual 1.5.4 12/9/2003 7:47 PM

11 Listeners & Loggers

11.1 Overview

Ant has two related features to allow the build process to be monitored: listeners and loggers.

11.1.1 Listeners

A listener is alerted of the following events:

• build started

• build finished

• target started

• target finished

• task started

• task finished

• message logged

11.1.2 Loggers

Loggers extend the capabilities of listeners and add the following features:

Receives a handle to the standard output and error print streams and therefore can log information to the console or the -logfile specified file.

Logging level (-quiet, -verbose, -debug) aware

• Emacs-mode aware

11.2 Built-in Listeners/Loggers

Classname Description Type

org.apache.tools.ant.DefaultLogger

org.apache.tools.ant.NoBannerLogger

The logger used implicitly unless overridden with the -logger command-line switch.

BuildLogger

This logger omits output of empty target output.

BuildLogger org.apache.tools.ant.listener.MailLogger

Extends DefaultLogger such that output is still generated the same, and when the build is finished an e -mail can be sent. org.apache.tools.ant.listener.AnsiColorLogger

Colorifies the build output.

BuildLogger

BuildLogger org.apache.tools.ant.listener.Log4jListener

Passes events to Log4j for highly customizable logging. org.apache.tools.ant.XmlLogger

11.2.1 DefaultLogger

Simply run Ant normally, or:

BuildListener

Writes the build information to an XML file. BuildLogger ant -logger org.apache.tools.ant.DefaultLogger

11.2.2 NoBannerLogger

Removes output of empty target output. ant -logger org.apache.tools.ant.NoBannerLogger

11.2.3 MailLogger

The MailLogger captures all output logged through DefaultLogger (standard Ant output) and will send success and failure messages to unique e- mail lists, with control for turning off success or failure messages individually.

Properties controlling the operation of MailLogger:

302/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

Property

MailLogger.mailhost

MailLogger.from

Description

Mail server to use

Mail "from" address

MailLogger.failure.notify Send build failure e -mails?

MailLogger.success.notify Send build success e -mails?

MailLogger.failure.to

MailLogger.success.to

Address(es) to send failure messages to, comma-separated

Address(es) to send success messages to, comma-separated

MailLogger.failure.subject Subject of failed build

MailLogger.success.subject Subject of successful build

Required

No, default "localhost"

Yes, if mail needs to be sent

No, default "true"

No, default "true"

Yes, if failure mail is to be sent

Yes, if success mail is to be sent

No, default "Build Failure"

No, default "Build

Success"

No ant -logger org.apache.tools.ant.listener.MailLogger

11.2.4 AnsiColorLogger

The AnsiColorLogger adds color to the standard Ant output by prefixing and suffixing ANSI color code escape sequences to it. It is just an extension of DefaultLogger and hence provides all features that DefaultLogger does.

AnsiColorLogger differentiates the output by assigning different colors depending upon the type of the message.

If used with the -logfile option, the output file will contain all the necessary escape codes to display the text in colorized mode when displayed in the console using applications like cat, more, etc.

This is designed to work on terminals that support ANSI color codes. It works on XTerm,

ETerm, Win9x Console (with ANSI.SYS loaded.), etc.

NOTE: It doesn't work on WinNT even when a COMMAND.COM console loaded with

ANSI.SYS is used.

If the user wishes to override the default colors with custom ones, a file containing zero or more of the custom color key-value pairs must be created. The recognized keys and their default values are shown below:

AnsiColorLogger.ERROR_COLOR=2;31

AnsiColorLogger.WARNING_COLOR=2;35

AnsiColorLogger.INFO_COLOR=2;36

AnsiColorLogger.VERBOSE_COLOR=2;32

AnsiColorLogger.DEBUG_COLOR=2;34

Each key takes as value a color combination defined as

Attribute;Foreground;Background. In the above example, background value has not been used.

303/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

This file must be specfied as the value of a system variable named ant.logger.defaults and passed as an argument using the -D option to the java command that invokes the Ant application. An easy way to ac hieve this is to add -Dant.logger.defaults= /path/to/your/file to the ANT_OPTS environment variable. Ant's launching script recognizes this flag and will pass it to the java command appropriately.

Format:

AnsiColorLogger.*=Attribute;Foreground;Background

Attribute is one of the following:

0 -> Reset All Attributes (return to normal mode)

1 -> Bright (Usually turns on BOLD)

2 -> Dim

3 -> Underline

5 -> link

7 -> Reverse

8 -> Hidden

Foreground is one of the following:

30 -> Black

31 -> Red

32 -> Green

33 -> Yellow

34 -> Blue

35 -> Magenta

36 -> Cyan

37 -> White

Background is one of the following:

40 -> Black

41 -> Red

42 -> Green

43 -> Yellow

44 -> Blue

45 -> Magenta

46 -> Cyan

47 -> White ant -logger org.apache.tools.ant.listener.AnsiColorLogger

11.2.5 Log4jListener

Passes build events to Log4j, using the full classname's of the generator of each build event as the category:

• build started / build finished - org.apache.tools.ant.Project

• target started / target finished - org.apache.tools.ant.Target

• task started / task finished - the fully qualified classname of the task

• message logged - the classname of one of the above, so if a task logs a message, its classname is the category used, and so on.

All start events are logged as INFO. Finish events are either logged as INFO or ERROR depending on whether the build failed during that stage. Message events are logged according to their Ant logging level, mapping directly to a corresponding Log4j level. ant -listener org.apache.tools.ant.listener.Log4jListener

304/305

Ant Manual 1.5.4 12/9/2003 7:47 PM

11.2.6 XmlLogger

Writes all build information out to an XML file named log.xml, or the value of the

XmlLogger.file property if present, when used as a listener. When used as a logger, it writes all output to either the console or to the value of -logfile. Whether used as a listener or logger, the output is not generated until the build is complete, as it buffers the information in order to provide timing information for task, targets, and the project.

By default the XML file creates a reference to an XSLT file "log.xsl" in the current directory; look in ANT_HOME/etc for one of these. You can set the property ant.XmlLogger.stylesheet.uri

to provide a uri to a style sheet. this can be a relative or absolute file path, or an http URL. If you set the property to the empty string, "", no XSLT transform is declared at all. ant -listener org.apache.tools.ant.XmlLogger

ant -logger org.apache.tools.ant.XmlLogger -verbose -logfile build_log.xml

11.3 Writing your own

See the Build Events section for developers.

Notes:

• A listener or logger should not write to standard output or error - Ant captures these internally and may cause an infinite loop.
