The OSGi users are used to this process of a painfull dependcy resolution,
luckily this is due only once at the beginning. While the package dependencies
are obvoius from the manifest, we should support the resolution of the correct
(OSGi-aware) Maven archives. This could be done by specifying a provisioning
configuration, e.g. an [Apache Karaf
Fature](https://karaf.apache.org/manual/latest/users-guide/provisioning.html)
or [Equinox/Tycho](https://wiki.eclipse.org/Tycho/Reference_Card) feature. I'll
need some time to prepare them and to set-up integration tests for these
platforms (but this is a prerequisite to prove the portability).
