A filelist example would be helpful.

As I mentioned in my recent user list thread, counting the number of files
isn't feasible for many reasons (overhead, brittleness, doesn't solve the
problem).  The goal again is to fail if explicitly named files don't exist. 
This ensures that the archive being build contains all of the expected
components.  This error should (be allowed to) cause a build failure, rather
than having the error occur later during product installation or run-time.

I suggest that any solution that involves re-specifying the named files is not
feasible due to brittleness (redundancy) and all the extra ant scripting.

I believe there continues to be merit in this feature request.  Since Resources
and Resource Collections don't adequately address this problem, perhaps
revisiting the initial request for additional attributes for <tarfileset> (and
others) is appropriate.  Or maybe someone can come up with a more elegant
solution.

If this problem is an issue for you too, please vote for this bug.  Thanks.
