I guess you could always create a pom file that uses the
maven:assembly plugin to populate your libs directory. Slightly
hacky, but it should do the trick.
A more powerful and robust solution would be an OSGi Bundle Repository:

If you're already using Nexus to host your Maven artefacts, then
upgrading to Pro is one of the quicker ways to get yourself an OBR.
