Gradle Failed: Could not determine java version from '9.0.1'

Works as designed
Issue description

Whenever I recompile my workspace or test Minecraft client environment (to test what I have made), I always get this: (except with the Minecraft client environment it's "clean runClient" instead of "clean build")

Executing gradle command: clean build
FAILURE: Build failed with an exception.
* What went wrong:
Could not determine java version from '9.0.1'.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
Task completed with return code 1 in 1656 milliseconds

I don't know how to solve this and I tried searching for the problem but I couldn't find a solution. I checked if my java needed updating but it says "your system has the recommended version of java" and the java version is "Java 8 Update 161"(just wanted to mention this just in case). Anyway thank you for reading my issue and I hope this can be solved so I can start making mods.

MCreator only works with Java 8. You are using Java 9. Please make Java 8 as the default Java version on your computer.
