How to clean project cache in Intellij idea like Eclipse's clean?

Question

Sometimes the IDE makes some error because of the cache. In Eclipse, we can use clean to solve the problem. But how can I do this in IntelliJ?

Maybe not THE answer, but it's definitely AN answer.

If nothing else is working for you, go the nuclear option: Close IDEA and delete the ".../.IntelliJIdea/system" directory using your local file system tools.

The .IntelliJIdea directory is usually found in your home directory. Your IDE configuration is in the ".../.IntelliJIdea/config" directory, so it should be fine.

Obviously, this is not the "IDEA" way to do it and would be completely unsupported by JetBrains. Also - I don't use Android Studio so I dunno if this will cause problems, but there you go.

It's worked for me before when I've had problems getting IDEA to start and nothing else works to get me going. Maybe back up your entire .IntelliJIdea directory if you have a morbid fear of losing all your work >.<
