Jenkins 2.0 Set Up on OSX

Prerequisite

• JAVA JDK 7 or above
• GIT
• MAVEN 3 or above

Install Jenkins

• Install jenkins via homebrew
• brew update && brew install jenkins

Starting Jenkins

After Jenkins is installed successfully, follow the instructions to start Jenkins on login

ln -sfv /usr/local/opt/jenkins/*.plist ~/Library/LaunchAgents

If you want to configure Jenkins to launch on system startup, for all users on OS X, then copy the plist file to the system Launchd location instead

sudo cp -fv /usr/local/opt/jenkins/*.plist /Library/LaunchDaemons

sudo chown `whoami` /Library/LaunchDaemons/homebrew.mxcl.jenkins.plist

You can always start Jenkins manually with

/usr/local/bin/jenkins

or if you have set up your PATH correctly when installing Homebrew, simply

jenkins

Starting Jenkins as service

Start service

brew services start jenkins

Stop service

brew services stop jenkins

Restart service

brew services restart jenkins

Restarting Jenkins

If you have an older version of Jenkins and you are upgrading it, then you can restart it this way:

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.jenkins.plist

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.jenkins.plist

Reference

Homebrew

Installing Jenkins OS X Homebrew

Maven doesn’t have a ‘lib’ subdirectory in Jenkins

Solution:

The ‘lib’ folder should be linking to libexec subdirectory. If you install your maven via homebrew, your maven home should /usr/local/opt/maven31/libexec. (Note: maven31 is the version I installed on my mac, change this according to your local setting.)
