Jenkins groovy:在管道中添加新行的变量

Question

我是Jenkins管道的新手，我的任务是使用cft创建aws云形成堆栈，堆栈名称应该是1-9999之间的随机数，因为我使用shuf命令来生成数字并存储在变量中。

pipeline {
agent  { node { label 'ansible-serverless' } }
stages {
   stage('Verify CFT') {
         options {
         withAWS(credentials:'jenkin_user_s3_9834',region:'us-east-1')
            }
        steps {
  node ('jenkins_ec2_9835'){
            script {
                    sh '''shuf -i 1-10000 -n 1 > outFile'''
                //    curDate = readFile 'outFile'.trim()
                    curDate = readFile 'outFile'.replaceAll("(?m)^[ \t]*\r?\n", "")
                    echo "The current number is ${curDate}"
                    }
                  sh "echo ${curDate}"

          cfnUpdate(url:'https://s3.amazonaws.com/artifacts/100GB_DB_ecosystem_full_enterprise.json', paramsFile:'/tmp/parameter-56.json',stack:"""CICD"${curDate}"-test""")
          cfnDescribe(stack:"CICD"${curDate}"-test")
         }
        }
       }
     }
   }

我能够打印这个变量，但是当我在堆栈创建管道中使用这个变量时，会自动添加新的行。

你能告诉我我在这里做错了什么吗？

看起来问题在于字符串插值(interpolation)。

尝试像这样替换curDate变量：

cfnDescribe(stack:"CICD${curDate}-test")
