Task compileJava failed, build failed. I don't know what to do.

Made the Demogorgon on Blockbench

I've got the versions and export right but I still have the problem.

I thought my Mcreator just couldn't accept 3D java entity models, but then I tried with a different blockbench custom mob

and there was no problem with the build or tasks.

Console error:

Sorry if I'm not supposed to put links, but the error log code is really big.
