I created a maven repository at home for my own code, which uses LWJGL under ardor3d. I bundled the natives up in to 3 jars, one for each platform. They can then be unzipped or anything that is wanted.
The issue is how to build them. LWJGL has a generation stage also.
I have tweaked JUtils so that there is a target on the ant script to bung some resources in to a maven repository, but the build is still ant based, maybe this is an interim step?
