Mac 安装 Jenkins 无法启动

MacOS 10.14.1 版本
Jenkins 2.716.2.pkg

sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist
# 启动 Jenkins 命令
sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist
# 停止 Jenkins 命令

localhost:8080 无法访问

ps -ef | grep jenkins

没有jenkins进程，启动失败。查看vim /Library/LaunchDaemons/org.jenkins-ci.plist配置文件得知日志路径，查看日志 cat /var/log/jenkins/jenkins.log中发现如下错误：

再次启动，访问 localhost:8080，访问成功～
PS：每次重新启动都需要执行以上命令
