分析

相同mvn命令，本地编译异常，通过jenkins编译报错，定位是用户权限问题

在shell中添加whoami打印jenkins用的是jenkins用户

jenkins是通过yum安装时自动创建的系统用户（没有目录，没有配置文件），无法通过su命令切换

要么改成root或其他用户，要么将mvn相关目录所有者改为jenkins（实测无效，可能时因为jenkins不是普通用户，无配置)

解决办法

将jenkins默认用户改为root或其他

//修改用户为root或其他
vim /etc/sysconfig/jenkins

 

//重启jenkins
systemctl restart jenkins

 

修改后编译成功！
