[JIRA] (JENKINS-37491) Build Origin PRs (merge with base branch) conducts rebuilds when baseline changes

Title: Message Title

Justin Rainwater commented on JENKINS-37491   Re: Build Origin PRs (merge with base branch) conducts rebuilds when baseline changes I wanted to add here a solution I found that feels like a nice workaround at least for my needs: In GitHub Org options check to build both merged and unmerged PRs so you have a bunch of PR jobs ending in -merge and -head. In the auto branch triggering field add PR-\d+-head so you auto build all head jobs but not all merge jobs. This will avoid the build storm that causes so many problems. From inside the Jenkinsfile add something like this: // have head job trigger merge job... if (autoTriggered() && env.BRANCH_NAME.endsWith('head')) { def headJobName = "${env.BRANCH_NAME}" def mergeJobName = (headJobName.substring(0, headJobName.length() - 4)).concat('merge') // replace head with merge build job: mergeJobName, wait: false return }       autoTriggered() is the function I added that returns false if cause description contains "Started by...". All this does is check if it's a head job and if so it triggers the corresponding merge job and exits.  It feels a little too simple and too good to be true, but at first glance it seems like this gives best of both worlds of auto triggering merge jobs only on changes to head and avoiding the buildStorm.    Add Comment   This message was sent by Atlassian JIRA (v7.3.0#73011-sha1:3c73d0e) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
