AW: [equinox-dev] [aspects] Pointcuts over types in separate bundle

["Meyer, Yang" <Yang.Meyer@xxxxxxxxxxxx>]

Martin,

Thanks for your quick response.

My target bundle imports the common bundle, but doesn't import any package from the aspect bundle (should it? why?).

I put both the common and the target bundles in the aspect bundle's "Eclipse-SupplementBundle" manifest header.

The way I see it, the problem is not that the *aspect* doesn't get woven, but that the *pointcut* isn't matched. I verified that the aspect is woven by writing an advice like before():call(* *.*(..)) && !within(MyAspect) {...}, which IS applied correctly.

Any ideas?
