We have a very similar issue in a couple of other projects. What we've 
done there is have a separate module for each artifact (jar) that is 
being produced and use dependencies to ensure that they get built in the 
correct order.

I don't think that will be necessary - I think it should be possible to 
compile code with the appropriate JDK. However, a similar issue applies 
to other classes such as the OSGi library that require licensing. For 
those, the user can install them in their local repository manually or, 
if terms permit, install them in a private repo inside their organization.

Will do.
