导出Eclipse RCP产品->“未解决的需求：Require-Bundle：org.eclipse.ui.views”

Question

I develop a feature based RCP application (using gef and draw2d) in Eclipse Mars and I want to generate an executable out of the product. For this I use the "Eclipse Product export wizard". But there is an error, when I start the executable:

I think the problem is that not all required libraries/plug-ins are included in the generated folder.

The same error occurs when I try to start the application via "product -> Overview tab -> Launch an Eclipse application". This problem can be solved by clicking "Run Configuarions -> Plug-ins -> Add Required Plug-ins". I assume that those Plug-ins which are added by "Add Required Plug-ins" are missing to run the executable.

Can anyone tell me, how to tell eclipse to include them when building the executable? Or am I missing something else?

I have already checked all boxes in "plug-in -> Build -> Binary Build/Source Build". I have also tried to include the missing libraries in the Build Tab. But nothing seems to work :/

thanks!

Answer 1

Assuming you are using an xxx.product file for your build. You need to go to the 'Contents' tab and click 'Add Required' to add the required plugins (or features) to the build.

This is separate from the 'Run Configuration' plugin configuration.

Answer 2

Thanks for the fast response!

Your hint gave me the clue to find the answer.

I had to add

• org.eclipse.ui
• org.eclipse.help
• org.eclipse.gef
• ...

to the 'Included Plug-ins' Tab within my feature (which I include in my product).

Thanks!
