How to check if string exists in array in a Jenkins Declarative pipeline step-CodePudding

I need to check if string exists in an array of strings, in a Jenkins Declarative pipeline step. I cannot find any documentation on operators, except some groovy docs, which suggest using !in, but that does not work, so not sure if those apply here. This is what I tried and it is not working, !in is not regocnized:

def approvalResult
pipeline {

....

  stage('Setup') {
    steps {
      script {
        approvalResult = input message: 'Approve prod deployment',
          submitter: '[email protected]',
          submitterparameter: ''
        
        echo "Build was approved by ${approvalResult}"
        //approvalResult contains string with the user email who clicked approve
  
        if(${approvalResult} !in ['[email protected]','[email protected]']){
          error("This user is not approved to deploy to PROD.")
        }
      }
    }
  }
}

CodePudding user response：

!in was added only in Groovy 3. Depending on how your Jenkins server and job is configured, your runtime groovy version might be <3. You can find out by:

println GroovySystem.version

Try the generic ! operator:

if(!(${approvalResult} in ['[email protected]','[email protected]'])){

CodePudding user response：

A functionally equivalent alternative for you is the contains method belonging to the list type. This will definitely work in Jenkins Pipeline Groovy:

if (!(['[email protected]','[email protected]'].contains(approvalResult))) {
  error('This user is not approved to deploy to PROD.')
}
