Hello, so I was trying to create a mob with a custom model into my mod and it's not compiling correctly. When I checked the build log there were multiple occurrences of an "error: cannot find symbol", and the listed failure was "execution failed for task ':compileJava.'" Attached here is the full build log, so if anyone could help me out on this it would be greatly appreciated. Thank you!
