patch
Applies a diff file to originals.
pathconvert
Converts Ant paths into platform-specific paths.
property
Sets properties in the project.
record
Logs output from the current build process.
rename
Deprecated in Ant 1.2; use the move task instead.
replace
Performs string replacement in one or more files.
rmic
Runs the rmic compiler.
sequential
Executes multiple tasks sequentiy; designed for use with the parel task.
signjar
Executes the javasign command-line tool.
sleep
Pauses the build for a specified interval.
sql
Executes SQL commands using JDBC.
style
Performs XSLT transformations.
tar
Creates a tar archive.
taskdef
Adds custom tasks to the current project.
touch
Updates the timestamp of one or more files.
tstamp
Sets the DSTAMP, TSTAMP, and TODAY properties.
typedef
Adds a DataType to the current project.
unjar
Expands a ZIP file, WAR file, or JAR file.
untar
Expands a tar file.
unwar
unzip
uptodate
Sets a property if one or more target files are up-to-date with respect to corresponding source files
war
Creates a Web Application Archive (WAR) file.
zip
Creates a ZIP file.
Invoke the default target on util_buildfile.xml in the current directory:
<ant antfile="util_buildfile.xml"/>
Invoke the clean target on build.xml in the gui directory:
<ant dir="gui" target="clean"/>
Invoke another buildfile, passing a new value for the builddir property. The value is explicitly set to utiloutput even if the property was defined elsewhere in the calling buildfile:
<ant antfile="util_buildfile.xml">
<property name="builddir" value="utiloutput"/>
</ant>
Copy
<copy todir="${builddir}/srccopy">
<fileset dir="${srcdir}">
<include name="**/*.java"/>
</fileset>
<filterset>
<filter token="VERSION" value="${app.version}"/>
</filterset>
</copy>
Here is a common target found in just about every Ant buildfile. It deletes the build directory and all of its contents:
<target name="clean" description="Remove all generated code">
<delete dir="${builddir}"/>
</target>
The first of the following examples specifies the text to write using the message attribute. The second example specifies the text to write by enclosing it within <echo>...</echo> tags.
<echo message="Building to ${builddir}"/>
<echo>You are using version ${java.version}
of Java! This message spans two lines.</echo>
Compile all Java source files in the com.oreilly.antbook package and subpackages, placing results in ${builddir}:
<javac srcdir="${srcdir}"
destdir="${builddir}"
includes="com/oreilly/antbook/**"/>
This task is commonly used in a prepare target that other targets depend on. This ensures that necessary destination directories are created before other targets are executed.
<target name="prepare">
<mkdir dir="${builddir}"/>
<mkdir dir="${deploydir}/docs"/>
<target name="compile" depends="prepare">
