<h1>Running Ant</h1>
|
|
<h2><a name="commandline">Command Line</a></h2>
|
|
<p> If you've installed Ant as described in the
|
|
<a href="install.html"> Installing Ant</a> section,
|
|
running Ant from the command-line is simple: just type
|
|
<code>ant</code>.</p>
|
|
<p>When no arguments are specified, Ant looks for a <code>build.xml</code>
|
|
file in the current directory and, if found, uses that file as the
|
|
build file and runs the target specified in the <code>default</code>
|
|
attribute of the <code><project></code> tag.
|
|
To make Ant use
|
|
a build file other than <code>build.xml</code>, use the command-line
|
|
option <nobr><code>-buildfile <i>file</i></code></nobr>,
|
|
where <i>file</i> is the name of the build file you want to use.</p>
|
|
If you use the <nobr><code>-find [<i>file</i>]</code></nobr> 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 <code>build.xml</code>. To have it search for a build file other
|
|
than <code>build.xml</code>, specify a file argument.
|
|
<strong>Note:</strong> If you include any other flags or arguments
|
|
on the command line after
|
|
the <nobr><code>-find</code></nobr> flag, you must include the file argument
|
|
for the <nobr><code>-find</code></nobr> flag, even if the name of the
|
|
build file you want to find is <code>build.xml</code>.
|
|
|
|
<p>You can also set <a href="using.html#properties">properties</a> on the
|
|
command line. This can be done with
|
|
the <nobr><code>-D<i>property</i>=<i>value</i></code></nobr> option,
|
|
where <i>property</i> is the name of the property,
|
|
and <i>value</i> is the value for that property. If you specify a
|
|
property that is also set in the build file
|
|
(see the <a href="CoreTasks/property.html">property</a> 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
|
|
<nobr><code>-DMYVAR=%MYVAR%</code></nobr> (Windows) or
|
|
<nobr><code>-DMYVAR=$MYVAR</code></nobr> (Unix)
|
|
to Ant. You can then access
|
|
these variables inside your build file as <code>${MYVAR}</code>.
|
|
You can also access environment variables using the
|
|
<a href="CoreTasks/property.html"> property</a> task's
|
|
<code>environment</code> attribute.
|
|
</p>
|
|
|
|
<p>Options that affect the amount of logging output by Ant are:
|
|
<nobr><code>-quiet</code></nobr>,
|
|
which instructs Ant to print less
|
|
information to the console;
|
|
<nobr><code>-verbose</code></nobr>, which causes Ant to print
|
|
additional information to the console; and <nobr><code>-debug</code></nobr>,
|
|
which causes Ant to print considerably more additional information.
|
|
</p>
|
|
|
|
<p>It is also possible to specify one or more targets that should be executed.
|
|
When omitted, the target that is specified in the
|
|
<code>default</code> attribute of the
|
|
<a href="using.html#projects"><code>project</code></a> tag is
|
|
used.</p>
|
|
|
|
<p>The <nobr><code>-projecthelp</code></nobr> option prints out a list
|
|
of the build file's targets. Targets that include a
|
|
<code>description</code> attribute are listed as "Main targets",
|
|
those without a <code>description</code> are listed as
|
|
"Other targets", then the "Default" target is listed
|
|
("Other targets" are only displayed if there are no main
|
|
targets, or if Ant is invoked in -verbose or -debug mode).

|
|
<p>For more information about <code>-inputhandler</code> see
|
|
<a href="inputhandler.html">InputHandler</a>.
|
|
<p>Easiest way of changing the exit-behaviour is subclassing the original main class:
|
|
<pre>
|
|
public class CustomExitCode extends org.apache.tools.ant.Main {
|
|
protected void exit(int exitCode) {
|
|
// implement your own behaviour, e.g. NOT exiting the JVM
|
|
}
|
|
}
|
|
</pre> and starting Ant with access (<tt>-lib path-to-class</tt>) to this class.
|
|
</p>
|
|
|
|
<h3><a name="libs">Library Directories</a></h3>
|
|
<p>
|
|
Prior to Ant 1.6, all jars in the ANT_HOME/lib would be added to the CLASSPATH
|
|
used to run Ant. This was done in the scripts that started Ant. From Ant 1.6,
|
|
two directories are scanned by default and more can be added as required. The
|
|
default directories scanned are ANT_HOME/lib and a user specific directory,
|
|
${user.home}/.ant/lib. This arrangement allows the Ant installation to be
|
|
shared by many users while still allowing each user to deploy additional jars.
|
|
Such additional jars could be support jars for Ant's optional tasks or jars
|
|
containing third-party tasks to be used in the build. It also allows the main Ant installation to be locked down which will please system adminstrators.
|
|
</p>
|
|
|
|
<p>
|
|
Additional directories to be searched may be added by using the -lib option.
|
|
The -lib option specifies a search path. Any jars or classes in the directories
|
|
of the path will be added to Ant's classloader. The order in which jars are
|
|
added to the classpath is as follows:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>-lib jars in the order specified by the -lib elements on the command line</li>
|
|
<li>jars from ${user.home}/.ant/lib (unless -nouserlib is set)</li>
|
|
<li>jars from ANT_HOME/lib</li>
|
|
</ul>
|
|
|
|
<p>
|
|
Note that the CLASSPATH environment variable is passed to Ant using a -lib
|
|
option. Ant itself is started with a very minimalistic classpath.
|
|
Ant should work perfectly well with an empty CLASSPATH environment variable,
|
|
something the the -noclasspath option actually enforces. We get many more support calls related to classpath problems (especially quoting problems) than
|
|
we like.
|
|
|
|
</p>
|
|
|
|
<p>
|
|
The location of ${user.home}/.ant/lib is somewhat dependent on the JVM. On Unix
|
|
systems ${user.home} maps to the user's home directory whilst on recent
|
|
versions of Windows it will be somewhere such as
|
|
C:\Documents and Settings\username\.ant\lib. You should consult your
|
|
JVM documentation for more details.

|
<h3><a name="files">Files</a></h3>
|
|
|
|
<p>The Ant wrapper script for Unix will source (read and evaluate) the
|
|
file <code>~/.antrc</code> before it does anything. On Windows, the Ant
|
|
wrapper batch-file invokes <code>%HOME%\antrc_pre.bat</code> at the start and
|
|
<code>%HOME%\antrc_post.bat</code> 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.</p>
|
|
|
|
<h3><a name="envvars">Environment Variables</a></h3>
|
|
|
|
<p>The wrapper scripts use the following environment variables (if
|
|
set):</p>
|
|
|
|
<ul>
|
|
<li><code>JAVACMD</code> - full path of the Java executable. Use this
|
|
to invoke a different JVM than <code>JAVA_HOME/bin/java(.exe)</code>.</li>
|
|
|
|
<li><code>ANT_OPTS</code> - 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.</li>
|
|
|
|
<li><code>ANT_ARGS</code> - Ant command-line arguments. For example,
|
|
set <code>ANT_ARGS</code> to point to a different logger, include a
|
|
listener, and to include the <code>-find</code> flag.</li>
|
|
<strong>Note:</strong> If you include <code>-find</code>
|
|
in <code>ANT_ARGS</code>, you should include the name of the build file
|
|
to find, even if the file is called <code>build.xml</code>.
|
|
</ul>
|
|
|
|
<h3><a name="sysprops">Java System Properties</a></h3>
|
|
<p>Some of Ant's core classes can be configured via system properties.</p>
|
|
<p>Here is the result of a search through the codebase. Because system properties are
|
|
available via Project instance, I searched for them with a
|
|
<pre>
|
|
grep -r -n "getPropert" * > ..\grep.txt
|
|
</pre>
|
|
command. After that I filtered out the often-used but not-so-important values (most of them
|
|
read-only values): <i>path.separator, ant.home, basedir, user.dir, os.name,
|
|
line.separator, java.home, java.version, java.version, user.home, java.class.path</i><br>
|
|
And I filtered out the <i>getPropertyHelper</i> access.</p>

|
If new properties get added (it happens), expect them to appear under the
|
|
"ant." and "org.apache.tools.ant" prefixes, unless the developers have a
|
|
very good reason to use another prefix. Accordingly, please avoid using
|
|
properties that begin with these prefixes. This protects you from future
|
|
Ant releases breaking your build file.

<h3>return code</h3>
|
|
<p>the ant start up scripts (in their Windows and Unix version) return
|
|
the return code of the java program. So a successful build returns 0,
|
|
failed builds return other values.
|
|
</p>
|
|
<p>Under Windows95 and 98, a special environment variable ANT_ERROR will be set
|
|
by the script ant.bat, because it is not possible to exit the script with a
|
|
specific errorlevel.</p>

<h2><a name="cygwin">Cygwin Users</a></h2>
|
|
<p>The Unix launch script that come with Ant works correctly with Cygwin. You
|
|
should not have any problems launching Ant from the Cygwin shell. It is
|
|
important to note, however, that once Ant is running 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 Cygwin paths, etc. In
|
|
particular when using the <code><exec></code> 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.
|
|
</p>
|
|
|
|
<h2><a name="os2">OS/2 Users</a></h2>
|
|
<p>The OS/2 launch script was developed to perform complex tasks. It has two parts:
|
|
<code>ant.cmd</code> which calls Ant and <code>antenv.cmd</code> which sets the environment for Ant.
|
|
Most often you will just call <code>ant.cmd</code> using the same command line options as described
|
|
above. The behaviour can be modified by a number of ways explained below.</p>
|
|
|
|
<p>Script <code>ant.cmd</code> first verifies whether the Ant environment is set correctly. The
|
|
requirements are:</p>
|
|
<ol>
|
|
<li>Environment variable <code>JAVA_HOME</code> is set.</li>
|
|
<li>Environment variable <code>ANT_HOME</code> is set.</li>
|
|
<li>Environment variable <code>CLASSPATH</code> is set and contains at least one element from
|
|
<code>JAVA_HOME</code> and at least one element from <code>ANT_HOME</code>.</li>
|
|
</ol>
|
|
|
|
<p>If any of these conditions is violated, script <code>antenv.cmd</code> is called. This script
|
|
first invokes configuration scripts if there exist: the system-wide configuration
|
|
<code>antconf.cmd</code> from the <code>%ETC%</code> directory and then the user configuration
|
|
<code>antrc.cmd</code> from the <code>%HOME%</code> directory. At this moment both
|
|
<code>JAVA_HOME</code> and <code>ANT_HOME</code> must be defined because <code>antenv.cmd</code>
|
|
now adds <code>classes.zip</code> or <code>tools.jar</code> (depending on version of JVM) and
|
|
everything from <code>%ANT_HOME%\lib</code> except <code>ant-*.jar</code> to
|
|
<code>CLASSPATH</code>. Finally <code>ant.cmd</code> calls per-directory configuration
|
|
<code>antrc.cmd</code>. All settings made by <code>ant.cmd</code> are local and are undone when the
|
|
script ends. The settings made by <code>antenv.cmd</code> are persistent during the lifetime of the
|
|
shell (of course unless called automatically from <code>ant.cmd</code>). It is thus possible to call
|
|
<code>antenv.cmd</code> manually and modify some settings before calling <code>ant.cmd</code>.</p>
|
|
|
|
<p>Scripts <code>envset.cmd</code> and <code>runrc.cmd</code> perform auxiliary tasks. All scripts
|
|
have some documentation inside.</p>

<h2><a name="viajava">Running Ant via Java</a></h2>
|
|
<p>If you have installed Ant in the do-it-yourself way, Ant can be started
|
|
from one of two entry points:</p>
|
|
<blockquote>
|
|
<pre>java -Dant.home=c:\ant org.apache.tools.ant.Main [options] [target]</pre>
|
|
</blockquote>
|
|
|
|
<blockquote>
|
|
<pre>java -Dant.home=c:\ant org.apache.tools.ant.launch.Launcher [options] [target]</pre>
|
|
</blockquote>
|
|
|
|
<p>
|
|
The first method runs Ant's traditional entry point. The second method uses
|
|
the Ant Launcher introduced in Ant 1.6. The former method does not support
|
|
the -lib option and all required classes are loaded from the CLASSPATH. You must
|
|
ensure that all required jars are available. At a minimum the CLASSPATH should
|
|
include:
|
|
</p>
|
|
|
|
<ul>
|
|
<li><code>ant.jar</code> and <code>ant-launcher.jar</code></li>
|
|
<li>jars/classes for your XML parser</li>
|
|
<li>the JDK's required jar/zip files</li>
|
|
</ul>
|
|
|
|
<p>
|
|
The latter method supports the -lib, -nouserlib, -noclasspath options and will
|
|
load jars from the specified ANT_HOME. You should start the latter with the most minimal
|
|
classpath possible, generally just the ant-launcher.jar.
|
|
</p>
|

Ant can be started in Ant via the <code><java></code> command.
|
|
Here is an example:
|
|
|
|
<pre>
|
|
<java
|
|
classname="org.apache.tools.ant.launch.Launcher"
|
|
fork="true"
|
|
failonerror="true"
|
|
dir="${sub.builddir}"
|
|
timeout="4000000"
|
|
>
|
|
<classpath>
|
|
<pathelement location="${ant.home}/lib/ant-launcher.jar"/>
|
|
</classpath>
|
|
<arg value="-buildfile"/>
|
|
<arg file="${sub.buildfile}"/>
|
|
<arg value="-Dthis=this"/>
|
|
<arg value="-Dthat=that"/>
|
|
<arg value="-Dbasedir=${sub.builddir}"/>
|
|
<arg value="-Dthe.other=the.other"/>
|
|
<arg value="${sub.target}"/>
|

</java>
