Gradle finished with non-zero exit value 255

Question

I am very new to Java coding and I decided to modify Minecraft as a fun project following a tutorial. When I went to run the Minecraft client from the debug menu, I received:

* What went wrong:
Execution failed for task ':runClient'.
> Process 'command '/Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home/bin/java'' finished with non-zero exit value 255

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

* Get more help at https://help.gradle.org

I've checked my code multiple times and there doesn't seem to be any differences between mine and the tutorial that I'm following. The tutorial was posted this year in January if that helps. I've looked for solutions for this problem but none were overly helpful.

Generally, non-zero exit code means an irregular exit. You should check out latest.log or debug.log in the running directory to inspect what was happened. They contain a crash report which helps identify your problem.
