Answer 3

If your code is working, simply try and restart your ide, it should work. seems to be a bug , especially caused if you move files around directly in the file system. Otherwise correct your code then.

NB: The other solutions above may work but are hacks. They may be temporal fixes and lead to unwanted effects. Don't alter any IDE settings you do not understand or remember to reconfigure later, it can be such a pain to maintain your environment.
