-1 I agree with Greg, using the version number in any (Client-side) jar could give maintenance problems, causing to update many files (shell scripts, compile references, deploy, etc), so having the version number only in main pivot-1.x.y-bin.zip/tar.gz (and the same for -src and -doc , -samples, etc) for me is a better choice.
Maven generated jars (for bin and for sources) have the version number (and any version has its subdir, ok), so this could be handled by the maven build process. Sandro
