Hello,
We are emailing you all today since we want your feedback on the beta version 2.4.6-beta-1 of the GitHub Branch Source Plugin.
Today, any PR that requires merging ends up cloning the associated GitHub repository on a Jenkins master, regardless of whether the Jenkinsfile was changed or not. In this release, we have significantly reduced the number of occurrences in which unnecessary full clones on the master happen. For more details on the issue, see
https://issues.jenkins-ci.org/browse/JENKINS-43194.
Please install, test out the plugin and let us know in this email thread or the Jenkins issue whether it works for you correctly or not.
