Verify OSGi bundles dependencies (import-package) programmatically

Question

I need to validate whether the imported packages of a bundle are fulfilled by a set of other bundles' export packages. This should not be very hard to implement but I know all the OSGi containers plus eclipse (when you do "validate bundles" in PDE) do this. I just don't know how to find that code. Does anyone know what classes/libraries I could use that already implement all this logic?

My goal is to give a list of files (bundles) in the file system and do an analysis whether the set of bundles is self-contained and if not to show all the missing external imports/requires. all this without actually having to run the bundles in a real container

Answer 1

You should look at the Resolver API in the OSGi spec. Apache Felix has a resolver implementation that is also used by the Equinox framework.
