Reproduction steps

1. Create a multibranch pipeline using the Bitbucket Server.
2. Fill in all the details and scan the job. ( it says: Finished: NOT_BUILT)

Expected Results

The expected outcome is that the branches are getting triggered. ( The same steps are performed with git, not bitbucket plugin and everything works as expected, the jobs are automatically scanned and the branches are build)

Actual Results

The job is not scanned and not triggered. The output result of the jobs is:
