IntelliJ : java release version 10 not supported

[mdparthi]

1. It can be resolved by updating the IntelliJ configuration:

• File → Settings-> Build, Execution, Development → Compiler → Java Compiler
• update Project bytecode version to the relevant version , for this error it should be 10.

2. also in File -> project structure and then take a look at Project and Modules tab. Set language level to 11 or whatever you’re using.
