有没有办法在Powershell脚本中使用Groovy变量？我的示例脚本如下。

  node {
  stage('Invoke Installation') {
  def stdoutpowershell
  def serverName = env.fqdn
  withEnv(['serverName =  $serverName']) {
      echo "serverName : $serverName"
      stdoutpowershell = powershell returnStdout: true, script: '''
          write-output "Server is $env:serverName"
      '''
  }
  }
