IntelliJ: Fatal error compiling: invalid target release: 1.8

Question

I\'m running a Java Maven project on IntelliJ, and I make sure that this project will be compiled by Java 1.8.

I set JRE to version 8 in Run/Debug Configuration

Answer 1

I assume you want to have it in version 8, despite so many comments telling you to set to 7.

You probably missed the setting for the maven runner, this is under Preferences -> Build, Exection, Deployment > Build Tools > Maven > Runner, see attached image. You need to set that to Java 8 as well.
