Issue1662463

Attached is a patch that will allow the Jython group to create a maven bundle at will.  This should help the project regularly produce maven bundles for each new release.

To use:

$ cd maven
$ ant -Dproject.version=2.2-beta-1
$ ant -Dproject.version=2.2-beta-1 install

The first ant call will actually build the bundle for submission to a maven repository.  The second line builds the files necessary for a local install.  Note that you must pass the version number as a JVM arg for ant.

Note that I borrowed quite heavily from the Apache Cayenne project for this work.  I am a Cayenne committer, so it made sense to me to leverage that work.  As such, I have included proper attribution in order to be compliant with the ASL 2.0.  If this is a problem, we'll need to come up with another way to do this -- in either event, I can upload my generated bundle now for the 2.2-beta-1 release.

There is a lot of clean-up opportunity here, since I was trying to get this done ASAP for the 2.2-beta-1 release.  For 2.2-beta-2, there could be some unification of this ant file with the main project one, in order to cut down on duplicate property definitions.

How significant are the changes from the Cayenne maven generation stuff?  I'd love it if we could point an svn:externals at Cayenne's version of this so we get updates automatically(and could send patches back if we find a maven change first).  It seems like most ant based projects could share a base of maven pom generation tasks.
