I was under the impression (from the release notes) that this plugin offered more configurable runtime functionality through declarative pipelines than is documented. The info pages for this plugin only describe how to connect Jenkins with Bitbucket and to set up a job that uses a Bitbucket repo. It does mention that build status is automatically updated in Bitbucket once the association has been made, but there is no documentation or elaboration of where this is posted or how this status is used.

Is there any support for multibranch pipeline? I would like to implement Merge Checks in Bitbucket PRs which would run the corresponding multibranch pipeline build for the hypothetically-merged branch, and would use the result as a Merge Check, preventing merges when the jenkins build is not Successful. This plugin does not appear to help with this. Am I missing something?
