What does the command “Fix Project Properties” exactly do?

Question

What does the \"Project->Android Tools->Fix Project Properties\" Eclipse command exaclty do?

I have read many times to use it, mostly in answers related with Android

Answer 1

Another result of running "Fix Project Properties" on a project is that any other projects in the same workspace that reference the project as an Android library may have jars which get linked in under "Android Dependencies" on the project build path.

This can result in multiple references to the same jar file or missing jar file references.

The fix is to remove those links from the related projects, remove the "Android Dependency" and re-run "Fix Project Properties".
