What feature do you want to see added?
I still use this in our production environment.
As it's deprecated, not expecting a new maintainer.
I have my own build that has several bug fix from me and others see the pull request #81
You could try my personal build at https://github.com/sunnyqeen/scm-sync-configuration-plugin/releases
I also updated several decencies in the snapshot version.
My build will require Jenkins 2.277 and above.
Use it as you wish, I may not add any new feature.
