My application is as simple as it can get:

Results in:

Error: java: error: release versoin 13 not supported

Answer 1

There's a  lot of places you must check:

• File -> Project Structure

• Edit Configurations (in drop down near RUN button)

• File -> Settings -> search for SDK

But what really worked for me after set everything above to my correctly Java 11 version was change this setting:

• File -> Settings -> Build, Execution, Deployment -> Compiler -> Java Copiler -> Project Bytecode Version

This setting was pointing to Java 13, so I changed to Java 11 and everything started to work as expected

Good luck

Answer 2

What worked for me was setting the language level to 13.

Go to File --> Project Structure --> Modules
