ant task to remove files from a jar

Question

How to write an ant task that removes files from a previously compiled JAR?

Let's say the files in my JAR are:

aaa/bbb/ccc/Class1 aaa/bbb/ccc/Class2 aaa/bbb/def/Class3 aaa/bbb/def/Class4 

... and I want a version of this JAR file without the aaa.bbb.def package, and I need to strip it out using ant, such that I end up with a JAR that contains:

aaa/bbb/ccc/Class1 aaa/bbb/ccc/Class2 

Thanks!

Have you tried using the zipfileset task?

<jar destfile="stripped.jar">     <zipfileset src="full.jar" excludes="files/to/exclude/**/*.file"/> </jar>

For example:

<property name="library.dir" value="dist"/> <property name="library.file" value="YourJavaArchive.jar"/> <property name="library.path" value="${library.dir}/${library.file}" /> <property name="library.path.new" value="${library.dir}/new-${library.file}"/>  <target name="purge-superfluous">     <echo>Removing superfluous files from Java archive.</echo>      <jar destfile="${library.path.new}">         <zipfileset src="${library.path}" excludes="**/ComicSans.ttf"/>     </jar>      <delete file="${library.path}" />     <move file="${library.path.new}" tofile="${library.path}" /> </target>
