Hello Mohica;

Regarding your second question,

if I understand correctly, you are trying to use an osgi bnd directive file
from maven, right ? Since the DM annotation API also contains a native bnd
plugin, then it is indeed possible to do this, and I think that the root
cause of the NoClassDefFoundError is that you don't have added a dependency
over the DM annotation plugin inside the maven-bundle-plugin, and when bnd
tries to load the DM plugin (thanks to the -plugin option), then it does
not find it because the dependency over
org.apache.felix.dependencymanager.annotation bundle is missing within the
maven-bundle-plugin.

I have tried the following which works fine for me (I don't use a separate
osgi.bnd file but I rather declare the "_plugin" option in the
maven-bundle-plugin pom xml element, but I think it's similar to that you
are doing). Notice that:
    - I use "_plugin" option from the maven-bundle-plugin instead of
"-plugin" bnd directive.
    - And since the DM annotation bnd plugin is invoked directly using the
_plugin option, then it is not needed anymore to
declare the DM maven bundle plugin, which is useless in this case.

Here it is:

    <build>

            </plugin>

Regarding your first question, I will get back to you later (tomorrow if
possible).

Hope this helps;
