Hmm... think I found an answer to my problem, though it's not one I like.
>From Jar.java:
public void setWhenempty(WhenEmpty we) {
log("JARs are never empty, they contain at least a manifest file",
Project.MSG_WARN);
}
It seems Jar.java overrides Zip.java's implementation of the setWhenempty method, so
the whenempty attribute is pretty much worthless when used with a Jar.
This may be a discussion better suited to ant-dev, but...
Why? I don't understand the reason for this change, and the cvs log entry isn't very
helpful. Finally, this change means I'm ending up with a bunch of empty JARs in my
classpath, and makes it a lot harder to create a generalized build script for use on
multiple projects.

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?
