How do I get support annotations in Eclipse?

I want to use support annotations in Eclipse. So that I can import these statements into Eclipse.

import android.support.annotation.IntDef;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;

      

        
        
        
      

    

You can read it here http://tools.android.com/tech-docs/support-annotations

Pls don't suggest using Android Studio!
