Lightweight checkout for PR merge jobs

Details

    • Blue Ocean 1.4 - beta 2

    Description

      Please pull in the changes made to the SCM API to reduce the number of checkouts required for pipelines. Related to JENKINS-33273

       

      There was a mention in the referenced issue about PRs needing special treatment: "there is no implementation currently for github-branch-source-plugin in the case of a PR job configured to merge with the base branch, as GitHub does not offer an API dedicated to this purpose. In the case that the merge can be assumed to be a fast-forward (there is no base branch change subsequent to the common ancestor), this plugin could in principle load content via API from the PR branch; it would still need to fall back to full checkout and Git merge otherwise." - https://issues.jenkins-ci.org/browse/JENKINS-33273?focusedCommentId=292273#comment-292273

            Please take a look at
            https://issues.jenkins-ci.org/browse/JENKINS-57195.
            If that looks like your issue, please try upgrading again, then close and reopen the PR that is failing. This is not a fix - but it will give me more information for debugging. It would also be useful to have a full stack trace for that failure.
