Question

Jenkins native Mac OS package installs by default in /Users/Shared/Jenkins and the war in /Applications/Jenkins. It runs as a daemon and restarts automatically in spite of a kill -9 command.

I added a winstone.properties in /Applications/Jenkins with a single prop, httpPort=9999.

Still app starts on 8080.

I even installed CLI and tried:

    java -jar jenkins-cli.jar -s http://127.0.0.1:8080/ shutdown

In short, I can’t force stop/start Jenkins and/or configure (I can via manual procedure, using a war though).

Suggestions?
Any idea how to configure the Jenkins

Try:

sudo defaults write /Library/Preferences/org.jenkins-ci httpPort '9999'

To check that it has worked use:

defaults read /Library/Preferences/org.jenkins-ci

Then kill the Jenkins process and let it restart.
