Problem when recompiling workspace

I am creating a road mod, and all that I have made so far is a guard rail. The model was made with Techne, but when I recompile the workspace I get a error. This is what comes in in the grandle log:

C:\Pylo\MCreator173\forge\build\sources\java\mod\mcreator\mcreator_crashBarrier.java:211: error: variable Shape1 is already defined in class ModelGuardRail1
		ModelRenderer Shape1;
		              ^
C:\Pylo\MCreator173\forge\build\sources\java\mod\mcreator\mcreator_crashBarrier.java:212: error: variable Shape1 is already defined in class ModelGuardRail1
		ModelRenderer Shape1;
		              ^
2 errors

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.

I am really confused and would appreciate some help :)
