查看问题：
找到路径下单条指令执行上述命令

#[root@git ~]# docker exec -it dfdf756561587 /bin/bash 登录容器查看

#git init /var/jenkins_home/workspace/test-one项目目录下面查看是否存在.git文件
#git fetch --tags --force --progress – http://git.cc.com/zeg/os.git +refs/heads/:refs/remotes/origin/
#git config remote.origin.url http://git.cc.com/zeg/os.git
#git config --add remote.origin.fetch +refs/heads/:refs/remotes/origin/
#git config remote.origin.url http://git.cc.com/zeg/os.git
#git fetch --tags --force --progress – http://git.cc.com/zeg/os.git +refs/heads/:refs/remotes/origin/

执行完成后，再到jenkins看看构建。
发现再次编译报错不同了：

到环境目录下直接执行：
#/usr/local/maven-3.5.4/bin/mvn -s /usr/local/maven-3.5.4/conf/settings.xml -gs /usr/local/maven-3.5.4/conf/settings.xml

此错误是项目没有指定执行目标。

<build>
<defaultGoal>compile</defaultGoal>
</build>

加入后再linux执行
bash-4.4# /usr/local/maven-3.5.4/bin/mvn -s /usr/local/maven-3.5.4/conf/settings.xml -gs /usr/local/maven-3.5.4/conf/settings.xml
编译完成。
那么jenkins为什么会报错误呢？

[test-one] $ /usr/local/maven-3.5.4/bin/mvn -s /usr/local/maven-3.5.4/conf/settings.xml -gs /usr/local/maven-3.5.4/conf/settings.xml
