Setup pom first version of the jars to be used as plain maven

jar produced by tycho doesn't contain maven dependencies (they are defined in the manifest)

one possible way to get jar with maven native dependencies is to mimic GEMOC pomfirst build:

It defines a second set of jars (the groupid is different) that recompile the same sources as the eclipse plugins but based on jar obtained from maven central/package registries

So we can decide which component need to be compiled for use by maven and which component is to be used by eclipse...

When a given component is used by both, the y each uses their dedicated dependency mechanism.
