Intellisense in IntelliJ no longer working
Answered
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?

Hi,
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.
General troubleshooting steps for problems with code completion:
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
I had this same issue after updating the value for the JDK being used by Maven (Settings -> Build, Execution, Deployment -> Build Tools -> Maven -> Importing). I had to do that because I was getting the "Cannot Reconnect" error when Maven was trying to import. Changing that JDK value seemed to fix the Maven issue but then Intellisense stopped working. I reverted that change, did a Maven reimport, and everything was back in working order.
