jenkins ssh 代理无法将 war 复制到远程服务器

Question

我是 jenkin 的新手，我创建了一个 jenkinFile 来构建 war 并根据以下教程将其复制到 tomcat 服务器上的远程计算机：

请在下面找到我创建的 jenkinFile：

#!/usr/bin/env groovy


pipeline {
environment {
    NAME = readMavenPom().getArtifactId()
}
agent any

options {
    timeout(time: 1, unit: 'HOURS')
    buildDiscarder(logRotator(daysToKeepStr: '10', numToKeepStr: '5', artifactNumToKeepStr: '2'))
}
stages {

     stage("Git Checkout"){
        steps{
             git branch: 'develop',
              credentialsId: 'jenkins', url: 'https://gitlab.gov/ih/ih-por.git'
             }
            }

    stage('Maven build') {

        steps {

         sh "mvn clean package"
         sh "mv target/*.war target/UI.war"

        }

    }

                 stage("deploy-dev"){
                     steps{
                        sshagent(['user-id-tomcat-deployment']) {
                        sh """
                        scp -o StrictHostKeyChecking=no target/UI.war
                        root@192.168.1.000:/opt/tomcat/webapps/
                        ssh root@192.168.1.000 /opt/tomcat/bin/shutdown.sh
                        ssh root@192.168.1.000 /opt/tomcat/bin/startup.sh
                         """
                          }
                        }
            }
}

}

我还在我的 jenkin 服务器上创建并添加了私钥。

然而，当我在 jenkins 上构建项目时，ssh 代理显示以下错误：

知道我做错了什么吗？

target/UI.war 后有一个新行，因此 scp 命令缺少目标参数。尝试在一行中使用完整的 scp 命令运行它：

stage("deploy-dev"){
     steps{
          sshagent(['user-id-tomcat-deployment']) {
               sh """
               scp -o StrictHostKeyChecking=no target/UI.war root@192.168.1.000:/opt/tomcat/webapps/
               ssh root@192.168.1.000 /opt/tomcat/bin/shutdown.sh
               ssh root@192.168.1.000 /opt/tomcat/bin/startup.sh
               """
           }
      }
}
