So I have a fileset containing files in one directory:
<fileset id="modules" dir="${modules.dir}">
<include name="core*.jar"/>
<include name="fileset*.jar"/>
<include name="upgrader*.jar"/>
<include name="hello*.jar"/>
</fileset>
However, these files are copied into the ${lib.dir}, i.e, the ${lib.dir} contains copies of core*.jar, fileset*.jar, etc. How do I delete these copied files?
Also, please note I can't use external libraries like ant-contrib.
Use a PatternSet to define the set of names. Then reference that PatternSet in any number of FileSets.
<patternset id="module.patterns">
<include name="core*.jar"/>
<include name="fileset*.jar"/>
<include name="upgrader*.jar"/>
<include name="hello*.jar"/>
</patternset>
<fileset id="modules" dir="${modules.dir}" >
<patternset refid="module.patterns"/>
</fileset>
UPDATE:
Given your comment that you want only the original files, try this:
<pathconvert pathsep="," property="flattened.modules" refid="modules">
<mapper type="flatten" />
</pathconvert>
<filelist id="libmodules" dir="${lib.dir}" files="${flattened.modules}"/>
