Hello. I've had many warnings about Dynamic-Import, and I suppose that's for good reasons.
I understand how and why the maven plugin doesn't analyze the Camel's routes and their components such as Groovy to build the bundle's dependencies. But how can I guess the packages that Groovy will need at runtime in Camel/ServiceMix/Karaf, and give a hand-made Import-Package for my bundle ? As I've explained before, I've done a test copying the packages that were detected at deployment time using a plain XML blueprint, but some packages are only imported when needed, and errors occur late... Any idea ? Have you experienced dependency management problem for other components ? Thanks again.
