Solved! I find out that I have two different versions of Logback in my dependency tree. When I exclude one of them, it start working.

@V0L0DYMYR, can you provide more information on the situation in which you see that error? As @joschi asked in response to the initial issue, can you check what version of Logback you’re pulling in, please? Providing the output of mvn dependency:tree could be helpful, for instance.

Have you tried running mvn clean before packaging the project?
