I'm trying to set up a non-default URL as part of a puppet script that installs Jenkins. I know how to edit the value via the web UI but I can't seem to find where the value is actually stored. I've looked through the jenkins_home folder and apache and have yet to find it.

It stores it in a rather unlikely place: hudson.tasks.Mailer.xml in Jenkins home folder.

                    52In case someone runs into this nowadays, it's `jenkins.model.JenkinsLocationConfiguration.xml` in recent versions – joostdevries Apr 10 '14 at 13:17

                    1do you guys know if changing the URL in that file should actually change the URL for Jenkins? Or must it be changed from the management console? – Kappacake Sep 05 '18 at 10:46
 
I'm on Jenkins 2.68 and it's stored at jenkins.model.JenkinsLocationConfiguration.xml under the Jenkins home folder.

If you don't find the URL when grepping Jenkins home, it's because you didn't saved the configuration. If not set, Jenkins fallback to request URL, without saving it on disk.
root@jenkins-dev:/var/lib/jenkins# grep jenkinsUrl *.xml
jenkins.model.JenkinsLocationConfiguration.xml:  <jenkinsUrl>http://jenkins-dev.lxc/</jenkinsUrl>
root@jenkins-dev:/var/lib/jenkins#

                    Jenkins home directory in mac (installed with homebrew) is ~/.jenkins – chuckSaldana Apr 16 '19 at 15:12
 
The url can be found in the UI/web app under configuration > Jenkins Location; alternatively, login to your server and cat the contents at this location: var/lib/jenkins/jenkins.model.JenkinsLocationConfiguration.xml

                    1Right. I'm aware of that file but as far as I can tell the URL value isn't stored in it. – nweiler Jul 31 '12 at 14:17
 
I did a grep for "http" in my Jenkins root directory led me to hudson.model.UpdateCenter.xml
