Description Konstantin Scheglov CLA 2010-05-08 06:33:34 EDT 
Build Identifier: 

I debug my plugin using sub-set of plugins from hosting Eclipse.
I've had already a lot of troubles with identifying why it does not work, even if I press "Add Required Plug-ins" button in launch configuration dialog. It seems that there are some implicit dependencies which can not by identified. I think that this is very bad, because now "Add Required Plug-ins" button is useless. For example equinox.ds always should be included, but HOW can I know this?

And after upgrading to 3.6M7 I stuck again. When I close Eclipse in logs NPE. I've added required plugins - still same exception. Can you tell me which plugins should be added? Or may be can you fix this NPE?

Reproducible: Always

Konstantin, there was some discussion about "who should know that DS is needed?" in the newsgroup.
http://dev.eclipse.org/mhonarc/lists/equinox-dev/msg06177.html

The answer is that the plug-ins can't establish this dependency because only the product configurer knows which implementation to use, etc.  We could, then, have PDE launch configs help detect this case...

Thank you for answer, Susan.
OK, now I understand why this happens.

Do you have idea what should be added to avoid NPE in this case?
