Jenkins pipeline with parallel

Question

Here is my Jenkins pipeline that i am trying to execute. I am following this tutorial:

pipeline {
    agent any
    stages {
        stage('one') {
            parallel "first" : {               
                    echo "hello"                
            },
            "second": {                
                    echo "world"            
            }
        }
        stage('two') {
            parallel "first" : {               
                    echo "hello"                
            },
            "second": {                
                    echo "world"            
            }
        }
    }
}

But the job fails with following message.

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 4: Unknown stage section "parallel". Starting with version 0.5, steps in a stage must be in a steps block. @ line 4, column 9.
           stage('one') {
           ^

WorkflowScript: 12: Unknown stage section "parallel". Starting with version 0.5, steps in a stage must be in a steps block. @ line 12, column 9.
           stage('two') {
           ^

WorkflowScript: 4: Nothing to execute within stage "one" @ line 4, column 9.
           stage('one') {
           ^

WorkflowScript: 12: Nothing to execute within stage "two" @ line 12, column 9.
           stage('two') {
           ^

4 errors

Can someone please help me out why this is failing.

Answer 1

You need to add a steps block after your stage declaration.

pipeline {
    agent any
    stages {
        stage('one') {
            steps {
                parallel("first": {
                    echo "hello"
                },
                        "second": {
                            echo "world"
                        }
                )
            }
        }
        stage('two') {
            steps {
                parallel("first": {
                    echo "hello"
                },
                        "second": {
                            echo "world"
                        }
                )
            }
        }
    }
}

You need to upgrade the Declarative Pipeline plugin on your Jenkins to Version 1.2 (Sept 21, 2017) or above
