Can't Run Gremlin Console due to "Exception in thread "main" BUG! exception in phase 'semantic analysis'... Unsupported class file major version 62"

I'm trying to learn Gremlin, I've installed the console from the website but when I try running the console with "bin/gremlin.sh", I get these errors:

Solved! I had to downgrade my java version to Java 11. I did so using instructions from this website: https://medium.com/@devkosal/switching-java-jdk-versions-on-macos-80bc868e686a
