I just realized I can achieve this using the <present> selector...
<target name="copy">
<copy todir="${dir1}/com/briankuhn/app">
<fileset dir="${dir2}/com/briankuhn/app"/>
</copy>
</target>
<target name="uncopy">
<delete failonerror="false" includeEmptyDirs="true">
<fileset dir="${dir1}/com/briankuhn/app">
<present targetdir="${dir2}/com/briankuhn/app"/>
</fileset>
</delete>
</target>
I'd still like to know if anyone knows of a resource that explains how to
support mappers in a custom task.
Thanks,
Brian
