Jenkinsfile issue while running script with sh – CentOS

I have the following Jenkinsfile

def ARTIFACTS_JOB_ID;
def ARTIFACTS_URL;

node('CentOs') {
    checkout scm
    stage('Example') {
        echo 'Download artifacts'
        sh 'curljson  --header "PRIVATE-TOKEN: tdzis3" "https://gitlab-sample.com/api/v4/projects/63/jobs" > jobs.json'
        ARTIFACTS_JOB_ID = sh(returnStdout: true, script: 'python GetID.py').trim()
        ARTIFACTS_URL = "https://gitlab-sample.com/api/v4/projects/63/jobs/${ARTIFACTS_JOB_ID}/artifacts"
        echo "======> $ARTIFACTS_URL"
        sh 'echo $ARTIFACTS_URL'
        sh 'curl --output artifacts.zip --header "PRIVATE-TOKEN: tdzis3" "$ARTIFACTS_URL"'
    }
}

while trying to get the artifact, it’s calling

'curl --output artifacts.zip --header "PRIVATE-TOKEN: tdzis3" ""' with empty url

Similarly 

echo "======> $ARTIFACTS_URL" //works fine
sh 'echo $ARTIFACTS_URL' // shows empty string, tried with ${ARTIFACTS_URL} aswell.

is there a way I can run it as below (so I don’t have to use sh)

def ARTIFACTS_JOB_ID;
def ARTIFACTS_URL;

node('CentOs') {
    checkout scm
    stage('Example') {
        script {
            echo 'Download artifacts'
            curljson  --header "PRIVATE-TOKEN: tdzis3" "https://gitlab-sample.com/api/v4/projects/63/jobs" > jobs.json
        }
    }
}

without sh I am getting invalid syntax error while doing
curljson --header

    Have you tried

    sh "curl --output artifacts.zip --header 'PRIVATE-TOKEN: tdzis3' '{$ARTIFACTS_URL}'"

    ?

    for multiple sh commands you could also use

    sh """
curl command here
cd command next 
etc
"""

    The variable declaration ARTIFACTS_URL = "https://..." is a Groovy global variable. Hence, it is not naturally available to the sh step as a shell variable.

    You need to wrap the commands inside the sh step with double quotes instead of single quotes as sh "echo $ARTIFACTS_URL" for Groovy to interpolate it as a Groovy variable.
