How can I make Jenkins CI with Git trigger on pushes to master?
I'm trying to set up Jenkins-ci for a project using GitHub. I've already set up Jenkins with the appropriate plugins. I want Jenkins to run build scripts only whenever someone on the project pushes to master. So far I've been able to set it up so that a build will be triggered anytime anyone pushes to anywhere, but that is too broad. I've done this with post-receive service hooks on Git.
I've read the Jenkins wiki, and a couple of tutorials, but this particular detail is missing... is it something to do with polling maybe? Or should work be done on the Git side, so that Git only triggers Jenkins when master is changed?
Answer
As already noted by gezzed in his comment, meanwhile there is a good solution (described in Polling must die: triggering Jenkins builds from a Git hook):
Set the Jenkins job's build trigger to Poll SCM, but do not specify a schedule.
Create a GitHub post-receive trigger to notify the URL
http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>?token=<get token from git to build remotely>This will trigger all builds that poll the specified Git repository.
However, polling actually checks whether anything has been pushed to the used branch.
It works perfectly.
