-If you are using &lt;antcall&gt; as a macro substitute, you really should look 
into this task.  It is not only going to simplify your build files but also

 Let's take an example from Ant's own build file.  Starting with Ant 1.6, we've 
split optional.jar into separate jars, one per library dependency.  This led to
 
 {{{ 
-&lt;jar destfile="${build.lib}/${optional.jars.prefix}-trax.jar"
-{{{     basedir="${build.classes}" }}}
-{{{     manifest="${manifest.tmp}"&gt; }}}
-{{{  &lt;selector refid="needs.trax"/&gt; }}}
-&lt;/jar&gt;
-
-&lt;jar destfile="${build.lib}/${optional.jars.prefix}-xalan1.jar"
-{{{     basedir="${build.classes}" }}}
-{{{     manifest="${manifest.tmp}"&gt; }}}
-{{{  &lt;selector refid="needs.xalan1"/&gt; }}}

 Starting a complete new Ant instance could be done with <java> task and the 
Launcher class. But the Launcher would exit the JVM. With
 the new <permission> datatype supported by <java> we can revoke that 
privilege. While trying that I realized that I have to grant some other 
privileges. Packed into a <macrodef> I got
