Dependency between 2nd (3rd, 4th, etc.) repositories

Question

Java

I have my own project on Github, which in turn uses a library from another (not mine) Github repository (one single class).
So, this library is not in the maven repository, but it is regularly updated in due time, and acquires new features. And you have to monitor this repository every time and update the class in your application.
Is there any way (direct or bypass) to automate this business? What would it look like?
