Can't export

Every time I export, it fails.

Here is the gradle log:

C:\Pylo\MCreator180\forge\build\sources\main\java\mod\mcreator\test.java:170: error: cannot find symbol
    mcreator_test mcreator_0 = new mcreator_test();
    ^
  symbol:   class mcreator_test
  location: class test
1 error

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Compilation failed; see the compiler error output for details.

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

From that I understand that it failed to compile Java, but how can I fix this issue?
