Bundle all "compile" dependencies into a fat jar bundle

[shumy]

Is it possible to build a fat jar with all transitive dependencies (conflicts resolved similar to maven), and select just the packages that I need to export for my plugin architecture?
No matter what I try, I always get in trouble with dependency resolution, last one was about "Invalid syntax for version" when generating the manifest for "raml-parser-2".
I will rather prefer to build a core bundle with all that I need, and skip this bunch of problems. I know this is not very good OSGi paradigm, I don't care!

PS: I'm working also with com.athaydes.osgi-run plugin
