针对上述错误，解决方法如下

1. 登录运行Jenkins job 的机器，kill 掉当前的Jenkins job

   # ps aux|grep java
   root     60195  0.0  0.0 111808  4032 ?        Ss   06:30   0:00 bash -c cd "/var/lib/jenkins" && java  -jar slave.jar
   root     60209  0.0  0.2 4612032 92992 ?       Sl   06:30   0:09 java -jar slave.jar
   #kill -9 60195

2.登录Jenkins server, 重新加载运行jenkins job 的机器

3.重新运行自动化job 上面的问题已经解决
