If we are using CD also for the tool (Which I like very much) I think we are missing some files like https://www.jenkins.io/doc/developer/publishing/releasing-cd/#update-maven-pom-and-config

Also incrementals must be enabled (I would suggest to check some plugin with CD enabled)

Will take a look into it

Hey! @jonesbusy I have enabled incrementals and added Dependabot. Will configure others later.
