Jenkins and Git?

Question

My firm right now is using Subversion and we have Jenkins pulling the SCM for changes and if anything changes it will do the Maven build.

We are moving to Git, but I don't see any way to pull a Git repository for changes... Am I missing something?

Answer 1

You can configure the Jenkins Git plugin to poll your repo for changes, but the recommended method is to add a post-receive (aka post-commit) hook to your repo. This way Jenkins is notified instantly on every commit.

Answer 2

You may not have the Git plugin installed, which is why you can't see the options. You would never have had to do this for subversion as the plugin for that ships by default. You can either use the automatic installer supplied in Jenkins to install the plugin, or you can do it manually (useful if you are behind corporate firewall).

Good luck with your migration. We have found a few gotchas in the Maven release plugin when performing a similar migration - if I had to do it again I would make some pro-type releases beforehand.
