In this context, the OSGi container is Eclipse/Equinox, so you just need to
install the peaberry bundles. The peaberry docs should explain how to do
this.

The entire concept of a fat or uber jar is anathema to OSGi IMHO.

You might also want to look at Tycho which seems closer to your use case.
But I don't do Eclipse development, so I can't say more than that.
