Actually there, is see below...

Thanks for the info! I managed to make the build work with a little
config tweaking using the maven-scr-plugin and
org.osgi.service.component.annotations. Briefly, I configured the
maven-scr-plugin to
- be active for the 'eclipse-plugin' packaging type
- depend on the annotation parser for the standard DS annotations (
also provided by the Apache Felix project )
- depend on a Maven artifact containing these annotations ( in my case
org.osgi.compendium )
- output its descriptors in the root directory, to get the generated
descriptors in OSGI-INF/*.xml
The last point is the one I'm not happy about, but if I generate them
in /target/scr-plugin-generated/OSGI-INF, per the Maven conventions, I
can't get the descriptors to resolve at runtime.

I'll post a more detailed description in the bug report early next week.
