我正在一个声明性的jenkins管道上工作，我试图登录到远程主机并执行shell脚本。下面是示例代码片段。我想知道如何将参数传递到我的script.sh脚本。

#!/bin/bash
echo "argument $1"

下面是管道脚本

hosts = [“x.x.x”, “x.x.x”]
pipeline {
  agent { node { label 'docker' } }

  parameters {
    choice(name: 'stageparam', choices: ['build', 'deploy'], description: ‘xyz’)
    string(name: 'Username', defaultValue: ‘abc’, description: 'enter username')
  }

  
  stages {
    stage('Setup') {
      steps {
        script {
          pom = getPom(effective: false)
        }
      }
    }
   
    stage('Deploy') {
      steps {
        script {

          def targetServers = null
          if (stageparam == "deploy") {
            targetServers = hosts
          } 

          targetServers.each { server ->
            echo "Server : ${server}"
            def remote = [:]
            remote.name = ‘server’
            remote.host = server
            remote.user = Username
            def pass = passwordParameter description: "Enter password for user ${remote.user} "
            remote.password = pass
            remote.allowAnyHosts = true
            stage('Remote SSH') {
                         sshPut remote: remote, from: ‘./script.sh', into: '.'
              sshScript remote: remote, script: "doc.sh ${Username}"
            }
          }
        }
      }
    }
  }
}

执行脚本时出现以下错误

/home/jenkins/workspace/script.sh Username does not exist.
