I am getting a java.lang.AbstractMethodError when testing a project (https://github.com/allegro/axion-release-plugin) that uses this project and the latest version of JGit (released today, 18 Dec 2019, 5.6.0.201912101111-r). I think this means that an interface has changed in JGit and this project needs to be recompiled.

The dependencies in this project are set to pull in the latest version of JGit. Please would you mind releasing a new recompiled version so I can make progress?
