Please don't use bug reports as a way to request help with configuration problems. It is likely that the link to your bitbucket repository in the Jenkins job is incorrectly configured. You'll need to open the job definition and confirm that the bitbucket URL you provided is correct.
If that doesn't resolve the issue, please provide a detailed description of the steps to duplicate your problem. You may also consider asking questions like this on the jenkins user mailing list. There are far more people monitoring the Jenkins users mailing list than monitor any specific plugin bug reports.
