Is this from an IDE or are you running commands in a terminal?

Im on mac running the command ./gradlew setupDecompWorkspace

Type javac -version and tell me what it says.

You are not up to date. Update your JDK.

Ugh sorry. I just typed in Java update and tried updating it from there and it said I was up to date. Anyway I updated and got this error now.

 

Could not determine java version from '12'.

 

[DaemonUmbra 354]

You need to use Java 8 for 1.12.2, just not the ancient version of 8 you had before.

It's currently doing its thing. Sorry it was such a simple solution, I'm all new to this. Thank you!
