I am trying to create a build pipeline based upon the Gradle tasks. I have viewed JenkinsFile configuration Pipeline-as-code-demo but I am unable to create a pipeline for gradle tasks. Please suggest me a possible way so that I can use the Jenkinsfile to automatically show the build pipeline just by reading the configurations from the Jenkinsfile.
Thankyou
In case your project uses Gradle Wrapper you can use the following snippet in your Jenkinsfile:
stage('Gradle Build') {
if (isUnix()) {
sh './gradlew clean build'
} else {
bat 'gradlew.bat clean build'
}
}
If you checkout to subdirectory sub-dir you might want to use
stage('Gradle Build') {
if (isUnix()) {
dir('sub-dir') {sh './gradlew clean build'}
} else {
dir('sub-dir') {bat 'gradlew.bat clean build'}
}
}
In case you're using Artifactory to resolve your build dependencies or to deploy your build artifacts, it is recommended to use the Pipeline DSL for Gradle build with Artifactory.
Here's an example taken from the Jenkins Pipeline Examples page:
node {
// Get Artifactory server instance, defined in the Artifactory Plugin administration page.
def server = Artifactory.server "SERVER_ID"
// Create an Artifactory Gradle instance.
def rtGradle = Artifactory.newGradleBuild()
stage 'Clone sources'
git url: 'https://github.com/jfrogdev/project-examples.git'
stage 'Artifactory configuration'
// Tool name from Jenkins configuration
rtGradle.tool = "Gradle-2.4"
// Set Artifactory repositories for dependencies resolution and artifacts deployment.
rtGradle.deployer repo:'ext-release-local', server: server
rtGradle.resolver repo:'remote-repos', server: server
stage 'Gradle build'
def buildInfo = rtGradle.run rootDir: "gradle-examples/4/gradle-example-ci-server/", buildFile: 'build.gradle', tasks: 'clean artifactoryPublish'
stage 'Publish build info'
server.publishBuildInfo buildInfo
}
Otherwise, you can simply run the gradle command with the sh or bat Pipeline steps.
In jenkins you can creates a jenkins pipeline using a script which is written in Jenkinsfile.
We write a script using 'stages' and 'node' as building block, these building blocks allow you to specify instructions that should be executed as part of jenkins pipeline.
To execute gradle build using JenkinsFile first check for Operating system and call appropriate shell that can execute that gradle task, as below:
Jenkinsfile
stage 'build_Project'
node{
if(isUnix()){
sh 'gradle build --info'
}
else{
bat 'gradle build --info'
}
}
Above code snippet create a stage with name build_project and execute gradle build script of the current project.

I'm learning how to use Jenkins and working on configuring a Jenkins file instead of the build using the Jenkins UI.
The source code management step for building from Bitbucket:
The build step for building a Docker container:
The build is of type multi configuration project:
Reading the Jenkins file documentation at https://www.jenkins.io/doc/book/pipeline/jenkinsfile/index.html and creating a new build using Pipeline :
I'm unsure how to configure the steps I've configured via the UI: Source Code Management & Build. How to convert the config for Docker and Bitbucket that can be used with a Jenkinsfile ?
The SCM will not be changed, regardless if you are using UI configuration or a pipeline, although in theory you can do the git clone from the steps in the pipeline, if you really insist convert the SCM steps in pure pipeline steps.
The pipeline will can have multiple stages, and each of the stages can have different execution environment. You can use the Docker pipeline plug-in, or you can use plain sh to issue the docker commands on the build agent.
Here is small sample from one of my manual build pipelines:
pipeline {
agent none
stages {
stage('Init') {
agent { label 'docker-x86' }
steps {
checkout scm
sh 'docker stop demo-001c || true'
sh 'docker rm demo-001c || true'
}
}
stage('Build Back-end') {
agent { label 'docker-x86' }
steps {
sh 'docker build -t demo-001:latest ./docker'
}
}
stage('Test') {
agent {
docker {
label 'docker-x86'
}
}
steps {
sh 'docker run --name demo-001c demo-001:latest'
sh 'cd test && make test-back-end'
}
}
}
}
You need to create a Pipeline type of a project and specify the SCM configuration in the General tab. In the Pipeline tab, you will have option to select Pipeline script or Pipeline script from SCM. It's always better to start with the Pipeline script while you are building and modifying your workflow. Once it's stabilized, you can add it to the repository.
I have a main pipeline in jenkins that will checkout the code , compile, test and build, then push image to docker. This is the high level of CI pipeline that I have. Say job name "MainJobA"
I need to create a new job , just for JavaDoc generation. For that i have created a new script in Git Repo and configured the same in Pipeline job.
Now i need to execute this sub job of javadoc generation and publishing the html reports from the workspace of "MainJobA" . I need to run the SubJobA's pipeline stages from
/home/jenkins/workspace/MainJobA
How can i achieve this?
There is build step exist in jenkins declarative pipelines.
Use it like:
pipeline {
agent any
stages {
stage ("build") {
steps {
build 'Pipeline_B'
}
}
}
}
Having some maven projects. I want to change it to a scripted pipeline in jenkins
To automate the following example you can use the Jenkins API via the groovy script console or an groovy system script to create you jobs programmatically.
Example for scripted Pipeline:
node{
stage ('Build') {
git url: 'https://github.com/cyrille-leclerc/multi-module-maven-project'
withMaven(
// Maven installation declared in the Jenkins "Global Tool Configuration"
maven: 'M3',
// Maven settings.xml file defined with the Jenkins Config File Provider Plugin
// Maven settings and global settings can also be defined in Jenkins Global Tools Configuration
mavenSettingsConfig: 'my-maven-settings',
mavenLocalRepo: '.repository') {
// Run the maven build
sh "mvn clean install"
} // withMaven will discover the generated Maven artifacts, JUnit Surefire & FailSafe & FindBugs reports...
}
}
You need the Pipeline Maven Plugin: https://wiki.jenkins.io/display/JENKINS/Pipeline+Maven+Plugin
I try to use Pipeline script and I arrive until last step.
The Pipeline script is the following code
node{
stage ('Build') {
git url: 'https://xxx#bitbucket.org/xxx/01-eureka.git'
withMaven(
// Maven installation declared in the Jenkins "Global Tool Configuration"
maven: 'M3',
// Maven settings.xml file defined with the Jenkins Config File Provider Plugin
// Maven settings and global settings can also be defined in Jenkins Global Tools Configuration
mavenSettingsConfig: 'my-maven-settings',
mavenLocalRepo: '.repository') {
// Run the maven build
sh "mvn clean install"
} // withMaven will discover the generated Maven artifacts, JUnit Surefire & FailSafe & FindBugs reports...
}
}
I have already been configured the maven and Java.
I don't know the error of the last step , I update all code.
I don't exact ENV as your's, but first thing first, you should check the your Jenkins workspace folder Jenkins\workspace\docker-app, to see if the git clone works as expected
If the source code are there, manual run the maven command to see if Maven finds the pom.xml correctly
I have a Maven project that builds a war file and a separate batch task inside the build job to deploy it to a server (this is basically a shell script executed on Jenkins).
This is the pipeline script:
node {
stage('Build') {
build job: 'core UAT'
}
stage('Deploy') {
build job: 'core UAT'
}
Is there a way to specify something like:
stage('Deploy') {
build job: 'core UAT -> Deploy'
}
I suppose I could manually copy paste the batch task steps into the pipeline stage, but I want to trigger as if it was run explicitly.
This may help:
