I have a program in java made through maven and packaged with assembly into a single jar with all the dependencies. I need to run this in docker so I need to be able to launch it with java.exe. The issue is that log4j2 throws and error. I have found a post with the same error as me and there is an answer. Unfortunately I do not understand what the answer is trying to say and I don’t have the reputation to add a comment and ask for clarification.
