我有Jenkins 2 Master和Jenkins 2 Slave。当我开始构建时，它是成功的，但当我检查构建控制台时，我可以看到多行以下消息：

Cannot contact slave-host: java.io.IOException: Remote call on Channel to /10.0.2.2 failed

下面是配置：

Jenkins Master- Docker

java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

Jenkins Slave-运行Oracle Linux

java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)

执行shell命令时会抛出错误消息。

部分Jenkins文件

stage("deploy") {
  node("slave-host") {
    step([$class: 'WsCleanup'])
      app_home = "/apps/tomcat"
      tomcat_home = "tomcat-server"
      id = 'package'
      sh "${app_home}/${tomcat_home}/bin/shutdown.sh &"
      unstash id
      sh "unzip *.zip"
      sh "cp *.war ${app_home}/wars"
  }
}

我做错什么了吗？
