Deploying a Maven Built OSGi Package in ServiceMix: "Unresolved constraint in bundle ..."

Question

I can build my projects "samba.interfaces" and "samba.message" without problems. But when I try to start "samba.message" bundle in ServiceMix (requires the "samba.interfaces" bundle that contains the package de.samba.common), I get the following error:

Error executing command: Unresolved constraint in bundle message [195]: module; 
(&(bundle-symbolic-name=de.samba.common)(bundle-version>=0.0.1))

So, what is the symbolic name used for? Does it have to be the same as the main package? This is the part of the POM that specifies the message bundle:

Any ideas what might cause this error?

Answer 1

Okay, I found the problem myself. Error executing command: Unresolved constraint in bundle message [195]: module; (&(bundle-symbolic-name=de.samba.common)(bundle-version>=0.0.1)) was completely unexpected, and it came from having a MANIFEST.MF file inside src/main/resources/META-INF that usually describes the bundle information if you're doing plugin/OSGi development. Seems that the Maven BND Plugin includes that file and ONLY generates new information if it isn't there.

So the problem was solved after removing src/main/resources/META-INF/MANIFEST.MF so the plugin could generate the proper one.
