Why an each loop in a Jenkinsfile stops at first iteration

Question

Here is the content of my Jenkinsfile :

node {
    // prints only the first element \'a\'
    [ \'a\', \'b\', \'c\' ].each {
        echo it
    }
}         


        

Answer 1

Here is example loop example with curl without NonCPS :

#!/usr/bin/env groovy

node('master') {
    stagesWithTry([
        'https://google.com/',
        'https://github.com',
        'https://releases.hashicorp.com/',
        'https://kubernetes-charts.storage.googleapis.com',
        'https://gcsweb.istio.io/gcs/istio-release/releases'
    ])
    stage ('ALlinOneStage'){
        stepsWithTry([
            'https://google.com/',
            'https://github.com',
            'https://releases.hashicorp.com/',
            'https://kubernetes-charts.storage.googleapis.com',
            'https://gcsweb.istio.io/gcs/istio-release/releases'
        ])
    }
}
//loop in one stage
def stepsWithTry(list){
    for (int i = 0; i < list.size(); i++) {
        try {
        sh "curl --connect-timeout 15 -v -L ${list[i]}"
        } catch (Exception e) {
            echo "Stage failed, but we continue"
        }
    }
}
//loop in multiple stage
def stagesWithTry(list){
    for (int i = 0; i < list.size(); i++) {
        try {
            stage(list[i]){
          sh "curl --connect-timeout 15 -v -L ${list[i]}"
            }
        } catch (Exception e) {
            echo "Stage failed, but we continue"
        }
    }
}
