问题
When running my RCP application in Eclipse it works correctly. If I export using the Eclipse Product export wizard and execute the application I get InjectionExceptions.
I've found another question here that is the exact same problem. I've added org.apache.felix.scr to the product configuration but I'm still getting the same issue. I'm assuming another plug-in needs to be added but Add Recommended doesn't add any more.

What could be causing this?
回答1:
I managed to fix this by finding the required plug-ins for the feature that @greg-449 mentioned.
First I added org.eclipse.emf.common and org.eclipse.emf.ecore to the Plug-ins and Fragments of the product file.
Next I right clicked and opened each of them to look at their dependencies. I then stepped through each dependency and if I didn't have it in my Required Plug-ins (plugin.xml) I would add it.
