Hi,

I'm looking for suggestions about how to handle the creation of patch
jar files. A patch jar file is one that contains only the classes that
have changed between two releases. Our production directories typically
look like this:

   application/bin     # contains start scripts
   application/jars    # contains jar files
   application/patch  # contains jar files

An application's class path consists of all the jar files in the patch
directory (if any) and then all the jar files in the jars directory.
This way the patched classes take precedence.

When a patch is needed the developers create a small jar file that
contains just the classes that have changed and stick it into the patch
directory. The Ant based build has a target called "patch-jar". It
creates a jar file using just the classes listed in a text file. This
text file is stored in SCM and thus patches can be reproduced.

So, my question is: How can I do something similar in Maven? 

Regards,
Christopher Helck
