This might not be the problem, but do you have a class implementing the interface?

7,287 Points@J.D. Sandifer, You are right. I couldn't figure out what was incompatible with what so i changed the build.gradle file to the same mvn dependencies in the video and it's working fine. The only down side is that i am not using an updated version of the man dependencies.

But I need more information. If you push the Gradle project to the GitHub and share a link, I can take a look and try to reproduce. Otherwise, it is hard to help.
