Here the picture:

 

I updated intellij from 2016.2 to .3 and I couldn't launch the game, it said I need to re-import the project, and I did, now i got those problems:

* Project SDK is not defined

* I cant launch the game

* setupDecompWorkspace wont work

 

Solved: Issue unknown but downloading new forge src and using it instead.

Go to Project Settings and set/add the JDK.

I don't get any errors, and I still cannot launch minecraft cause I don't know what errors around.

 

Edit: I cannot find the minecraft files either.

 

Edit: after command: setupDecompworkspace, cmd seems to work and I saw this in the list: Maybe something u interested in. the command is not yet fully finished

EDIT: Starting minecraft will result in these problems:
