If you are trying the suggested ways and still no chance, be sure about your order:

1. Delete your .idea/
2. Invalidate and Restart Cache afterwards
3. Import maven projects from your maven tool

If you did not invalidate and restart cache just after deleting your .idea/, Intellij keeps generating it and that was keeping error in my case.
