Intellisense in IntelliJ no longer working


I'm currently running IntelliJ IDEA 13.1. While running IntelliJ 13 intellisense/autocomplete stopped working. I tried upgrading and it still doesn't work.

I can explicitly invoke code completion using ctrl+space. I looked in Settings->Editor->Code Completion and nothing looks out of place. Is there somewhere else that turns this feature on/off?

Try the File | Invalidate Caches & Restart menu option.

Also see if disabling all downloaded plugins under File | Settings | Plugins | Installed and restarting the IDE helps.

I had the same problem. I solved it using these steps:

1. Go to Filte\Project Structure\Project

2. Change the used SDK with another one (I also had a kotlin one) and press "Apply changes"

4. Select back the sdk you want to use and press "Apply changes"

After these steps, the Intellij worked
