I want to set dynamic variable in Jenkinsfile and below is my Jenkinsfile
def determineProjectByBranch(branchName) {
String projectName = "";
if (branchName.contains("api")) {
projectName = "api";
} else if (branchName.contains("auth")) {
projectName = "auth";
}
return projectName;
}
pipeline {
agent any
stages {
stage("Build") {
environment {
PROJECT_NAME = determineProjectByBranch("${GIT_BRANCH}")
}
steps {
script {
PROJECT_NAME = determineProjectByBranch("${GIT_BRANCH}")
}
echo "branch name: ${GIT_BRANCH}"
echo "project name: " + PROJECT_NAME // it shows empty value
echo "project name: ${PROJECT_NAME}"
sh "chmod +x gradlew"
sh "./gradlew ${PROJECT_NAME}:clean ${PROJECT_NAME}:build"
}
}
}
}
As you can see the above code i want to use function so that it can set the dynamic value but i can't find the right way to set variable dynamically.
I also tried the below code but it didn't work either.
def determineProjectByBranch(branchName) {
String projectName = "";
if (branchName.contains("api")) {
projectName = "api";
} else if (branchName.contains("auth")) {
projectName = "auth";
}
return projectName;
}
def projectName
pipeline {
agent any
stages {
stage("Build") {
steps {
script {
projectName = determineProjectByBranch("${GIT_BRANCH}")
}
echo "branch name: ${GIT_BRANCH}"
echo "project name: " + projectName // it shows empty value
echo "project name: ${projectName}"
sh "chmod +x gradlew"
sh "./gradlew ${projectName}:clean ${projectName}:build"
}
}
}
}
You may think the function returns empty value but when i build with below code it shows expected value
def determineProjectByBranch(branchName) {
String projectName = "";
if (branchName.contains("api")) {
projectName = "api";
} else if (branchName.contains("auth")) {
projectName = "auth";
}
return projectName;
}
def projectName
pipeline {
agent any
stages {
stage("Build") {
steps {
echo "branch name: ${GIT_BRANCH}"
echo "project name: " + determineProjectByBranch("${GIT_BRANCH}") // it shows expected value
echo "project name: ${projectName}"
sh "chmod +x gradlew"
sh "./gradlew ${PROJECT_NAME}:clean ${PROJECT_NAME}:build"
}
}
}
}
I'm not sure define variable depends on Jenkins version but mine is 2.361.2. Any help would be appreciate thank you in advance🙇
I just hardcoded the values and removed irrelevant parts and the following seems to work fine for me.
def determineProjectByBranch(branchName) {
String projectName = "";
if (branchName.contains("api")) {
projectName = "api";
} else if (branchName.contains("auth")) {
projectName = "auth";
}
return projectName;
}
pipeline {
agent any
stages {
stage("Build") {
environment {
PROJECT_NAME = determineProjectByBranch("api123")
}
steps {
echo "branch name:"
echo "project name: " + PROJECT_NAME // it shows empty value
echo "project name: ${PROJECT_NAME}"
}
}
}
}
Output
[Pipeline] withEnv
[Pipeline] {
[Pipeline] echo
branch name:
[Pipeline] echo
project name: api
[Pipeline] echo
project name: api
[Pipeline] }
[Pipeline] // withEnv
[Pipeline] }
[Pipeline] // stage

I have declarative pipeline as below and it runs 2* and 3* stages in parallel, pasted the blue ocean diagram below.
pipeline {
agent { label 'my_node' }
options {
timestamps()
parallelsAlwaysFailFast()
}
stages {
stage('1') {
steps {
script {
step([$class: 'WsCleanup'])
}
}
}
stage('2') {
parallel {
stage("2.1") {
steps {
script {
sh 'echo hi 2.1'
}
}
}
stage("2p") {
steps {
script {
sh 'echo hi 2p'
}
}
}
}
}
stage('3') {
parallel {
stage('3.1') {
steps {
script {
sh """
echo hi 3.1
"""
}
}
}
stage('3.2') {
steps {
script {
sh """
echo "hi 3.2"
"""
}
}
}
}
}
stage('4') {
steps {
script {
sh "echo end"
}
}
}
}
}
But I am looking to run 2p in parallel to 2* and 3*, like shown below, is there a way?
I tried to use paralle under parallel, to start 2p in parallel to 2 and 3, and nested parallel to run 3.1. and 3.2 underneath, but declarative pipeline is not allowing nested parallel.
You can't do this only with Declarative syntax. But you can achieve this with a combination of Scripted and Declarative syntax. One thing to note is, AFAIK there is no visualization support for nested parallel stages as of now. There is a feature request for this here.
Following is a sample pipeline you can use as a reference for your use case.
pipeline {
agent any
options {
timestamps()
parallelsAlwaysFailFast()
}
stages {
stage('1') {
steps {
script {
step([$class: 'WsCleanup'])
}
}
}
stage('2 AND 3') {
steps {
script {
parallel getWrappedStages()
}
}
}
stage('4') {
steps {
script {
sh "echo end"
}
}
}
}
}
def getWrappedStages() {
stages = [:]
stages["Step2.1"] = { stage('2.1') {
sh """
echo hi 2.1
"""
}
parallel parallel3xstages()
}
stages["Step2.p"] = { stage('2.p') {
sh """
echo hi 2.p
"""
}
}
return stages
}
def parallel3xstages() {
stages = [:]
stages["Step3.1"] = { stage('3.1') {
sh """
echo hi 3.1
"""
}
}
stages["Step3.2"] = { stage('3.2') {
sh """
echo hi 3.2
"""
}
}
return stages
}
I have a Jenkinsfile like this
pipeline {
agent { label 'master' }
stages {
stage('1') {
steps {
script {
sh '''#!/bin/bash
source $EXPORT_PATH_SCRIPT
cd $SCRIPT_PATH
python -m scripts.test.test
'''
}
}
}
stage('2') {
steps {
script {
sh '''#!/bin/bash
source $EXPORT_PATH_SCRIPT
cd $SCRIPT_PATH
python -m scripts.test.test
'''
}
}
}
}
}
As you can see, In both stages I am using the same script and calling the same file.
Can I move this step to a function in Jenkinsfile and call that function in script? like this
def execute script() {
return {
sh '''#!/bin/bash
source $EXPORT_PATH_SCRIPT
cd $SCRIPT_PATH
python -m scripts.test.test
'''
}
}
Yes, It's possible like below example:
Jenkinsfile
def doIt(name) {
return "The name is : ${name}"
}
def executeScript() {
sh "echo HelloWorld"
}
pipeline {
agent any;
stages {
stage('01') {
steps {
println doIt("stage 01")
executeScript()
}
}
stage('02') {
steps {
println doIt("stage 02")
executeScript()
}
}
}
}
I've a pipeline where multiple stages run in parallel but if any of the stages fails, I want to get its name to show failed stage. With following code, even if it fails in first stage ie Checking Redmine access, it always show last stage as failed i.e. Checking Reviewers list. This is because it runs in parallel and latest assigned value is picked up.
pipeline {
agent {
label {
label "<machine-ip>"
customWorkspace "workspace/RedmineAndReviewboardProject/SVNCheckoutTest"
}
}
stages {
stage('Verify inputs') {
parallel {
stage('Checking Redmine access') {
steps {
script {
FAILED_STAGE = env.STAGE_NAME
echo "Redmine"
sh'''hello'''
}
}
}
stage('Checking SVN access') {
steps {
script {
FAILED_STAGE = env.STAGE_NAME
echo "SVN"
}
}
}
stage('Checking Reviewers list') {
steps {
script {
FAILED_STAGE = env.STAGE_NAME
echo "Reviewer"
}
}
}
}
}
}
post {
failure {
script {
echo "Failed stage is " + FAILED_STAGE
}
}
}
}
Is there any way I can get exactly failed stage of parallel running stages? or it will be also ok with me if parent stage name is returned as failed stage.
I believe you can use a post { failure { block for each stage : see https://www.jenkins.io/doc/book/pipeline/syntax/#post
pipeline {
agent {
label {
label "<machine-ip>"
customWorkspace "workspace/RedmineAndReviewboardProject/SVNCheckoutTest"
}
}
stages {
stage('Verify inputs') {
parallel {
stage('Checking Redmine access') {
steps {
script {
echo "Redmine"
sh'''hello'''
}
}
post {
failure {
script {
echo "Failed stage is ${STAGE_NAME}"
}
}
}
}
stage('Checking SVN access') {
steps {
script {
FAILED_STAGE = env.STAGE_NAME
echo "SVN"
}
}
post {
failure {
script {
echo "Failed stage is ${STAGE_NAME}"
}
}
}
}
stage('Checking Reviewers list') {
steps {
script {
FAILED_STAGE = env.STAGE_NAME
echo "Reviewer"
}
}
post {
failure {
script {
echo "Failed stage is ${STAGE_NAME}"
}
}
}
}
}
}
}
}
I have the following Jenkinsfile which I believe is setup correctly. I used https://jenkins.io/doc/book/pipeline/syntax/#sequential-stages as an example but for some reason when I run this in jenkins I am receiving,
WorkflowScript: 11: Unknown stage section "stages". Starting with
version 0.5, steps in a stage must be in a steps block
Can someone tell me what I am missing or doing wrong?
pipeline {
agent {label 'windows'}
stages {
stage('Quick Build') {
steps {
echo 'Building'
}
}
stage('Deploy to Dev') {
// when {
// branch 'develop'
// }
stages {
stage('Building Distributable Package') {
steps {
echo 'Building'
}
}
stage('Archiving Package') {
steps {
echo 'Archiving Aritfacts'
archiveArtifacts artifacts: '/*.zip', fingerprint: true
}
}
stage('Deploying Dev') {
steps {
echo 'Deploying'
timeout(time:3, unit:'DAYS') {
input message: "Approve build?"
}
}
}
}
}
stage('Deploy to Test') {
when {
branch 'develop'
}
steps {
echo 'deploying..'
timeout(time:3, unit:'DAYS') {
input message: "Approve build?"
}
}
}
stage('Deploy to Prod') {
when {
branch 'release'
}
steps {
timeout(time:3, unit:'DAYS') {
input message: "Deploy to Prod?"
}
echo 'Deploying....'
}
}
}
}
Thanks in advance!
This ended up being a problem in version 2.107.3. Once upgraded to 2.121.2 this functionality started working.
I have the following setup:
Jenkinsmaster, no docker installed
Jenkinsslave, docker is installed, label dockerslave
When I run the following pipeline:
pipeline {
agent { node { label 'dockerslave' } }
stages {
stage('Example Build') {
agent { docker { image 'maven:3-alpine' } }
steps {
echo 'Hello, Maven'
sh 'mvn --version'
}
}
stage('Example Test') {
agent { docker { image 'openjdk:8-jre' } }
steps {
echo 'Hello, JDK'
sh 'java -version'
}
}
}
}
I get the following logoutput:
[Pipeline] node
Running on dockerslave in /home/jenkins/workspace/docker-
declarative
[Pipeline] {
[Pipeline] stage
[Pipeline] { (Example Build)
[Pipeline] node
Still waiting to schedule task
There are no nodes with the label ?latest?
The job doesn't proceed and hangs.
What is the problem here?
The problem was the missing:
reuseNode true
The fixed example:
pipeline {
agent {
node { label 'dockerslave' } }
stages {
stage('Example Build') {
agent {
docker {
reuseNode true
image 'maven:3-alpine'
}
}
steps {
echo 'Hello, Maven'
sh 'mvn --version'
}
}
stage('Example Test') {
agent {
docker {
reuseNode true
image 'openjdk:8-jre'
}
}
steps {
echo 'Hello, JDK'
sh 'java -version'
}
}
}
}
