Problem:
Since you added MCServerUpdater code directly into your project, you would waste some time to check my upstream changes everytimes I occasionally made an update. And since I don't actively maintain it and you want total control of the code quality, you may want to control the code into your quality.
Solution:
Make your own fork of MCServerUpdater and make changes into your fork. Make it standalone so that other developers can contribute. Publish your fork to jitpack or something.
EDIT: I can't just change the ownership to you since it's my personal project and it has my core library, so making a fork is the only way.
