Hi, Thanks for your reply. Being a newbie, I'm finding a li'l hard to grasp the concept maybe. I agree, that embedding transitive dependency might not be the greatest idea since it contradicts OSGI fundamental. But at the sametime what bothers me is how do we address the non-osgi jars ? I can "n" number of jars in my project which maybe have other transitive dependencies. I don't see how efficient is the process of manually identifing them and make them OSGi enabled. I found the transitive dependency support comes handy in these cases.
Unfortunately, I'm still not able to figure out how the <Embed-Transitive> property works for the maven-plugin-bundle. After,trying all possible combinations(so far), I haven't seen a single instance where a transitive jar got embedded in the bundle. I perhaps, need to do more reading to understand this. Can you pls share any pointers for best practises in this regard? Appreciate your help... -Thanks On Fri, Jun 10, 2011 at 11:41 AM, <[email protected]> wrote: > > > Shamik, > > > > Embedding the transitive dependencies is one of those things that you can do > in OSGi, but usually you shouldn't.
