Plugin that enables Jenkins to approve commits on Bitbucket. In a sense, you may compare it to how Travis and Github are working together.
The plugin creates a global configuration option to supply a username and a password. That user needs to have write access to your Bitbucket Repository.
In your job, create a Post-Build-Step called Approve commit on bitbucket. Configure that step and set the repository owner and the repository name.
Don't hesitate to file an issue or a pull request. This is my first attempt to creating a Jenkins plugin so appreciate any suggestions.
Cheers
