Execution failed for task ':compileJava'.

Hi Anton, good afternoon, I am trying to create my .jar following the instructions in the documentation but I get an error. I can't find the error. Any idea?

/traccar> ./gradlew assemble       

> Task :compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> invalid source release: 11
