Well, that basically worked. But I had to put the "exclude" not in the Patte=
rnSet itself, but in the FileSet that referenced the PatternSet, like this:
<FileSet dir=3D".">
   <PatternSet refid=3D"other-jars"/>
   <exclude name=3D"*" unless=3D"support.abc"/>
</FileSet>

Not totally ideal, maybe, but it does work. I think what you said would work=
 with the incomplete example I gave, but I also was using the PatternSet som=
etimes in conjunction with other PatternSets and the exclude in those cases m=
essed me up (excluded everything when I didn't want to).  But the idea does w=
ork in that having both the include and the exclude gives a non-empty file l=
ist always, whether the feature is enabled or not, which avoids the problem o=
f an empty list implying "copy everything".=20

So, thank you very much!
