Let’s take 35 minutes to explain how you can write your new plugins using the Eclipse 4 concepts and definitively stop to use the E3 UI extension points.
Writing pure Eclipse 4 plugins is easier (thanks to injection, application model fragments, spies, …) and simplifies the unit tests for UI components.
This talk will also explain how to mix your pure E4 plugins properly with your E3 legacy plugins. It will be a complementary talk if you could not attend the E4 tutorial.
The time has come to start to develop with the new concepts and to stop to use legacy libraries!
