I was wondering how one could change Jenkins\' default port 8080. Using linux or windows, this is simply done with the configuration file. But the Mac config file of Jenkins
Just write the following command in the terminal:
sudo defaults write /Library/Preferences/org.jenkins-ci.plist httpPort 9999 sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist
That should resolve it.
