True, of course there isnt a 1:1 mapping of source to class - which is why I
mentioned <depends> as well. But Java really is a pain when it comes to
trying to work out this kind of stuff esp. since javac does its own thing
when compiling. I do wish it would only compile those files I tell it
to....Hmm, jikes?

Anyway here's a thought. What about having v1.0.jar of your system built and
on the classpath for the compiler. Blow away your source tree and then sync
out of your SCM only those files that changed post v1.0. Next compile this
source tree and jar up anything it produces. Then stick this jar
(v1.0patch1.jar) in front of the old one on the classpath and perhaps Bob's
your uncle. Maybe? Or am I talking  rubbish again and have I been doing too
much powerpointing recently :-)
