    If this is your first install, automatically load on login with:
      mkdir -p ~/Library/LaunchAgents
      cp #{plist_path} ~/Library/LaunchAgents/
      launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    If this is an upgrade and you already have the #{plist_path.basename} loaded:
      launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
      cp #{plist_path} ~/Library/LaunchAgents/
      launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    Or start it manually:
      java -jar #{libexec}/jenkins.war
