I've run into an odd problem recently with the "whenempty" attribute of the <jar>
task.
The following test ant script, when run in a directory containing ONLY the build.xml
file,
creates both jars. This puzzles me; as best I understand the <jar> task, it seems
like
creation of the second jar should be skipped. When I open the jar, it's empty
(excepting
the Ant-generated manifest file). It seems like this problem popped up recently; I
don't
remember having it under Ant 1.3. I'm currently using Ant 1.4 (compiled on September
3 2001).
Bug or (more likely) user error?
