      Bitbucket Server 5.6.0

      When building a PR that hasn't had changes to the Jenkinsfile within the PR, we see the following error at the beginning of each build:

      Branch event
ERROR: Could not do lightweight checkout, falling back to heavyweight
java.io.FileNotFoundException: URL: /rest/api/1.0/projects/TCD/repos/deployer-ish/browse/Jenkinsfile?at=PR-216&start=0&limit=500

      This is because Bitbucket Server does not expose the Jenkinsfile on such a PR, i.e.

      // 20180203112420
// https://stash.my.com//rest/api/1.0/projects/TCD/repos/deployer-ish/browse/Jenkinsfile?at=PR-216&start=0&limit=500

{
  "errors": [
    {
      "context": null,
      "message": "The path \"Jenkinsfile\" does not exist at revision \"PR-216\"",
      "exceptionName": "com.atlassian.bitbucket.content.NoSuchPathException"
    }
  ]
}

      This should not be an error, as if there are no changes to the Jenkinsfile, then Bitbucket will not include the file on that request.
