在Mac上使用jenkins的过程里，执行某些shell脚本时出现报错，查看报错信息发现是当前用户没有权限删除某个文件夹导致的。于是在网上搜了很多资料，发现可用的是少之又少，于是自己写篇博客总结一下如何在OSX操作系统中修改jenkins的默认用户

①打开终端terminal

②停止jenkins： launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist

③编辑/Library/LaunchDaemons/org.jenkins-ci.plist，文件内容如下

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

  <dict>

    <key>StandardOutPath</key>

    <string>/var/log/jenkins/jenkins.log</string>

    <key>StandardErrorPath</key>

    <string>/var/log/jenkins/jenkins.log</string>

    <key>EnvironmentVariables</key>

    <dict>

      <key>JENKINS_HOME</key>

      <string>/Users/Shared/Jenkins/Home</string>

    </dict>

    <key>GroupName</key>

    <string>wheel</string>#此处为用户所属的组，改为root用户所属的组

    <key>KeepAlive</key>

    <true/>

    <key>Label</key>

    <string>org.jenkins-ci</string>

    <key>ProgramArguments</key>

    <array>

      <string>/bin/bash</string>

      <string>/Library/Application Support/Jenkins/jenkins-runner.sh</string>

    </array>

    <key>RunAtLoad</key>

    <true/>

    <key>UserName</key>

    <string>root</string>#此处为jenkins默认用户，默认值为jenkins用户，改为root用户

    <key>SessionCreate</key>

    <true/>

  </dict>

</plist>

④更改jenkins文件夹的所属用户与组：

chown -R root Jenkins/

chgrp -R wheel Jenkins/

⑤启动jenkins：launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist
