title: Bitbucket webhooks to trigger Jenkins project
body: <p>I have a simple Jenkins pipeline job that does a bunch of things and calls other jobs. There is no repo associated with the job. But this job should be called when a pull request is created in a certain repo in Bitbucket. This was easy with Gitlab where I just had to add a webhook with the Jenkins job url on Gitlab. How do I achieve this with Bitbucket? It looks like it always needs a repo url in Jenkins for the webhook to be triggered but I have no repo.
  Ex my pipeline job on Jenkins is</p>
  <pre><code>    stage('Stage 1'){
          echo &quot;hello, world!&quot;
      }
  }
  </code></pre>
  <p>I want to trigger this build when a PR is created on Bitbucket for repo xyz.</p>
  <p>Or in general how to make Jenkins pipeline jobs with pipeline script and Bitbucket Webhooks work? All either speak about freestyle job or multibranch job or pipeline job with Jenkinsfile</p>
