How to exclude from zipgroupfileset?

Question

I am using ANT 1.7.1 but I am getting an error that exclude is not supported in zipgroupfileset target.

I am trying to do below operation -

<zipgroupfileset >
                <fileset dir="lib">
                <excludes>
         <exclude>META-INF/*.SF</exclude>
         <exclude>META-INF/*.DSA</exclude>
         <exclude>META-INF/*.RSA</exclude>                                       
                </excludes>

            </fileset>
   </zipgroupfileset>

Please help.

Thanks!

Accepted answer didn't work for me, I did the following:

    <zipgroupfileset dir="lib" excludes="<jars containing the signatures>"/>
    <zipfileset src="lib/<jar containing the signatures>" excludes="META-INF/*.SF,META-INF/*.DSA"/>

This solution requires you to know which jars has been signed (contains .SF,.DSA,.RSA) files. You'll need a zipfileset for each of those jars.

zipgroupfileset cannot inspect the contents of the jars.
