Replace/overwrite resource files of another plugin [message #526647]

Hi!

I have multiple plug-in projects, one of them implementing some third-party logic. This one is configured by a bunch of properties files. A default configuration resides directly here.

Now I depend on this plug-in from other projects. The problem is that I'd like to override some of its resources to change its behaviour. I learned that different plug-ins have different class loaders, which makes that not a trivial task. By simply placing the changed properties files in the plug-in's classpath this cannot be achieved.

My question is: it is possible somehow?

Thanks a lot!

Regards,
Alexander

Hi again,

I'm still experimenting with the issue stated above.

I learned that there is something called buddy classloaders. With that in mind I modified the dependent plug-in's manifest (A) and added "Eclipse-BuddyPolicy=registered". My own plug-in (B) got "Eclipse-RegisterBuddy: A". This should make the plug-in A look for classes (and resources?) in plug-in B's classloader.

What happens is somewhat strange: plug-in A behaves different now, but still does NOT respect my configuration (which lies in plug-in B).

Does this buddy stuff really work with resources too?

How can the order where to search for them be defined?

Thanks,
Alexander

It works for me now.

The pronlem seems to be that plug-in A still prefers its own resources, and only looks for its buddies' resources if it cannot found them.

So I extended one of its classes, specified another resources path, and voila: the resources are loaded from my plug-in.

Cheers,
Alexander
