• is main Jenkins plugin which act as main build engine (from Jenkins 2.0)
• replay feature let to run job with modified by hand Jenkinsfile

It is possible to write Jenkinsfile's as Groovy scripts (advanced) or using Declarative Pipeline Syntax.

jenkinsfile

node {
    stage("a") {
    }
    stage("b") {
    }
    stage("c") {
        parallel (
            'taskA': { stage("1") { }},
            'taskB': { stage("2") { }},
        )
    }
    stage("archive") {
        archiveArtifacts artifacts: 'out_*/*.*'
        archiveArtifacts artifacts: 'contiki/tools/cc2538-bsl/cc2538-bsl.py'    
    }
}

NOTE:

• parallel expect map as argument. https://www.cloudbees.com/blog/parallelism-and-distributed-builds-jenkins

Creating your first Pipeline https://jenkins.io/doc/pipeline/examples/ https://www.blazemeter.com/blog/how-to-use-the-jenkins-scripted-pipeline Distributed builds

archiveArtifacts:

• Directory//*.* → All the files recursively under Directory * /*.* → all the files in the workspace
• /*.xml → all xml files in your workspace. * Directory//*.xml → All the xml files recursively under Directory

archiveArtifacts artifacts: 'file.extension'''
archiveArtifacts artifacts: 'teste.js'
archiveArtifacts artifacts: '*.js'
archiveArtifacts artifacts: 'teste.js', onlyIfSuccessful: true

Jenkinsfile

pipeline {
    agent any
    stages {
        stage('Download') {
            steps {
                sh 'make config'
                sh 'echo "artifact file" > generatedFile.txt'
            }
        }
    }
    post {
        always {
            archiveArtifacts artifacts: 'generatedFile.txt', onlyIfSuccessful: true
        }
    }    
}

You may also declare whether scripts need to explicitly request that library (detailed below), or if it is present by default. Furthermore, if you specify a version in Jenkins configuration, you can block scripts from selecting a different version.

/workspace/project@script is checked out on Master only to get Jenkinsfile - it can be safely deleted /workspace/project@2 - folder where build is performed (can be on slave) /workspace/project@tmp - ?
