I understand there are other topics on this already but their solutions have not successfully been able to help me. I am creating a plugin and there is a class called CommandErrors that has only static references and methods in it. Here is the error printing out in the console:
SEVERE: null

How can I fix this NoSuchMethod error? I know for sure the method and class does exist. Thanks!
I figured out not the problem but a solution to the problem. Although I'm sure it's definitely better programming practice and just in general better to fix the problem itself the proper way but I have found that creating a class with a different name but with the same body fixes the problem.
Hope this helps others!
