PRs failing to build due to missing branch

XMLWordPrintable

      We have attached our repo to jenkins using the multi branch plugin. Our workflow is as follows:

      1. developer creates a fork of repo
      2. makes new $branch in fork and edits code
      3. makes pull request to upstream to be pulled to $branch on upstream
      4. jenkins picks up on the pull request and starts building and doing tests

      When the pull request to upstream is made, $branch does not exist yet until it has been accepted. This is a feature of Bitbucket which allows this.

      When we updated from version 2.1.1 to 2.2.3 of Bitbucket Branch Source Plugin, the workflow above did not work anymore. The pipeline log is as follows:

Finished: FAILURE

      When I create the branch on upstream manually, the build does work and is being correctly build from the fork.
