I'm a longtime idea user.
I recently switched my laptop from windows to linux.
When opening my projects, the idea editor cannot resolve any 'java.lang.*' objects. Everything is highlighted red.
I've search the internet and tried the following:
-dropped and added jdk's, changed the jdk for the project, etc.
-deleted the system folder
-switched jdk versions (I originally had started on IBM jdk and thought that was the problem)
-renamingmy Idea director (~/.IntellijIdea11)
I found that creating a new project (from scratch) succeeds (i.e. editor can resolve java.lang.String)..;just not old projects
I'm using Idea 11.17 on Ubuntu 14.04LTS
