I would like to read the source code of various Gradle implementation classes in the IntelliJ IDEA. However, I always get only the Interface (e.g. org.gradle.api.Project.java or org.gradle.api.Task.java).
I would rather like to view the classes implementing Project and Task which are used by Gradle. I would like to see how things are implemented.
How do I quickly show those implementing classes in IDEA?
