Search an Extension Point
While indexing application processes, extension points that are used in the application processes too will be indexed. We can search extension points either using the resource library search or extensions tab in the resource library.
Using Resource Library Search
Window --> Show View --> Resource Library --> Search. Can use prefix ext: to search extensions only.
Using Resource Library Extensions Tab
Using the extensions tab, we can find all the extension points in the workspace projects and as well as dependent jars. Window --> Show View --> Resource Library --> Extensions Tab.
