maven版本：apache-maven-3.5.0
jenkins版本:Jenkins1.596.2
java版本:jdk1.7.0_80
我在jenkins下创建了一个maven类型的job, git配置和maven项目源码都没有问题，
maven3.5.0我在linx环境中测试页是正常的。
在一切看似都正常的情况下我立即构建maven项目却报如下错误，起初我以为是~/.m2/settings.xml文件的读取权限的问题，当我把chorm -R jenkins:jenkins .m2都改成 jenkins权限后依然有问题。
最后我把maven换成3.0.4版本后就正常了。 正当我欣喜之时又爆错， 但是是另外的错误 后续跟上解决方案和原因
估计一切的一切都是jenkins运行用户权限的问题， 把jenkins的运行用户改为root一切问题都没有了
如何修改运行jenkins进程的linux帐号？
1、找的jenkins的配置文件，一般是/etc/sysconfig/jenkins
2、修改下面的参数为相应的用户，比如JENKINS_USER="root"
## Type: string
## Default: "jenkins"
## ServiceRestart: jenkins
#
# Unix user account that runs the Jenkins daemon
# Be careful when you change this, as you need to update
# permissions of $JENKINS_HOME and /var/log/jenkins.
#
JENKINS_USER="jenkins"
