Getting the src directory in an Eclipse IProject?

Question

I am trying to programmatically access the src/ directory in an Eclipse project (type IProject).

Basically, my problem is as follows:

• INPUT: IProject
• OUTPUT: Return the src directory in this IProject
• Notes: The src directory may be called anything else (it need not be "src" every time -- it is decided when creating the java project)

Any pointers on how I can do this?

Answer 1

1. Cast the IProject to IJavaProject.
2. Get the array of IPackageFragmentRoot using getAllPackageFragmentRoots()
3. Get the one(s) which have getKind() == IPackageFragmentRoot.K_SOURCE
