Antlets are designed to be (optionally) downloaded and imported by the importantlet task sample code
Sample
<?xml version="1.0"?> <project default="dist" basedir="." name="hello-world"> <description>Helloworld template project.</description> {{{ <typedef resource="org/apache/ant/antlet/antlib.xml" />
<importantlet name="init" href="http://ant.apache.org/antlets" />
<target name="dist" >
<echo message="Build dir is defined in init as ${build.dir}"/>
</target>
</project>
}}}
This will download and automatically import http://ant.apache.org/antlets/init/xbuild.xml Which looks like
<?xml version="1.0"?> <project basedir="." name="init.antlet"> <description>Standard Init.</description> {{{ <property name="build.dir" value="${basedir}/build}" />
<mkdir dir="${build.dir}"/>
</project>
}}}
