[FIXED] Jenkins : Copy artifacts from one agent to another from last stage

Issue

I am using more than one agents in my declarative pipeline. Is there anyway to copy artifacts (input.txt) from agent1 to agent2? here is my declarative pipeline,

pipeline {
    agent none

    stages {
        stage('Build') {
            agent {
                label 'agent1'
            }

            steps {
                sh 'echo arjun > input.txt'

            }
            post {
                always {
                    archiveArtifacts artifacts: 'input.txt',
                            fingerprint: true
                }
            }

        }
        stage('Test') {
            agent {
                label 'agent2'
            }

            steps {
                sh 'cat input.txt'
            }
        }
        }
    }
 

Solution

You can use Copy Artifact Plugin that can do exactly that.

Given your Jenkinsfile, it then turns into this:

pipeline {
    agent none

    stages {
        stage('Build') {
            agent { label 'agent1' }
            steps {
                sh 'echo arjun > input.txt'
            }
            post {
                always {
                    archiveArtifacts artifacts: 'input.txt', fingerprint: true
                }
            }
        }

        stage('Test') {
            agent { label 'agent2' }
            steps {
                // this brings artifacts from job named as this one, and this build
                step([
                    $class: 'CopyArtifact',
                    filter: 'input.txt',
                    fingerprintArtifacts: true,
                    optional: true,
                    projectName: env.JOB_NAME,
                    selector: [$class: 'SpecificBuildSelector',
                            buildNumber: env.BUILD_NUMBER]
                ])

                sh 'cat input.txt'
            }
        }
    }
}
