jenkins ssh agent fail to copy war to remote server

Question

I am new to jenkin, I have created a jenkinFile to build a war and copy it to a remote machine on tomcat server based on the following tutorial:

https://thenucleargeeks.com/2020/05/31/declarative-jenkins-pipeline-to-deploy-java-web-application/

Please find below jenkinFile which i have created:

#!/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
                         """
                          }
                        }
            }
}

}

I have also created added the private key on my jenkin server.

However when I build the project on jenkins the following error is displayed by ssh agent:

    [Pipeline] { (deploy-dev)
[Pipeline] sshagent (hide)

Any idea what I am doing wrong please?

You have a new line after the target/UI.war so the scp command is missing the target parameter. Try to run it with the full scp command in a single line:

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
               """
           }
      }
}
