I have created a Jenkins Pipeline job. In this job I want to do the build using Ant. I have configured the Ant variable in Manage **Jenkins > Global Tool Configuration** as Ant1.9.1= D:\path_to_hybris\hybris\bin\platform\apache-ant-1.9.1.
In a freestyle jenkins Job, I know that the build.xml location can be specified as in the below screenshot:
but I am unable to understand how to specify the ant groovy script beyond this point, especially where can we mention the path to build.xml file:
def antHome = tool 'Ant1.9.1'
????
????
you can use ant wrapper in Jenkins`s pipeline groovy script.
withAnt(installation: 'LocalAnt') {
// some block
sh "ant build"
//for windows
bat "ant build"
}
Remember to configure the ant tool in the Jenkins "Global Tool Configuration" with the same name "LocalAnt".
You can try this:
def antVersion = 'Ant1.9.1'
withEnv( ["ANT_HOME=${tool antVersion}"] ) {
sh '$ANT_HOME/bin/ant target1 target2'
}
Under Windows this would look like this (I didn't test it though):
def antVersion = 'Ant1.9.1'
withEnv( ["ANT_HOME=${tool antVersion}"] ) {
bat '%ANT_HOME%/bin/ant.bat target1 target2'
}
This assumes that you have Ant configured in Jenkins with name 'Ant1.9.1'.
I needed this multiple times within the same Jenkinsfile that needs to be executed on both linux and windows agents so I created a method for it.
You can call ant like this
callAnt("-v -p")
if you add this method definition to your jenkinsfile
def callAnt(String Parameters) {
if (isUnix()) {
env.PATH = "${tool 'ant'}/bin;${env.PATH}"
sh "ant ${Parameters}"
}
else {
env.PATH = "${tool 'ant'}\\bin;${env.PATH}"
bat "ant ${Parameters}"
}
}

I have this jenkins stage where I am trying to pass a paramter to a gradle task. It seems like the gradle task does not recieve it
Jenkins
stage('Version Bump') {
steps {
script {
version = (new Date().format('YYYY.ww.')) + env.BUILD_NUMBER
sh './gradlew bumpVersion --no-daemon -Pversion=${version}'
}
}
}
Gradle task
task bumpVersion() {
doFirst {
println version
}
}
The version isnt printed. I have confirmed the value is correct by echo-ing in the jenkins file.
It should work if you use double quotes on the following line:
sh "./gradlew bumpVersion --no-daemon -Pversion=${version}"
Otherwise Groovy doesn’t replace ${version} and then the run shell finds the unset version shell variable and expands it to an empty string (which is then printed by Gradle – making it appear as if nothing was printed at all).
I have a doubt on the below issue can someone please help me on this.
I wanted to pass maven pom.xml properties from the shell in jenkins pipeline which needs to be substituted by maven and not by groovy or shell.
Example:
pipeline {
agent any
stages {
stage('build') {
steps {
sh 'mvn -Doracle.db.url=${db.url} package'
}
}
}
}
Here ${db.url} should be substituted by the url from maven setting.xml file properties and not by groovy or shell in Jenkins pipeline.
I have tried different combination but it gives me error in Jenkins pipeline.
If the above maven property is constant(some constant url) then it is easy to pass but when I wanted to pass any variable property (${db.url}) then I am not able to do so with any syntax.
If you want maven to evaluate ${db.url}, it has to be like
pipeline {
agent any
stages {
stage('build') {
steps {
sh 'mvn -Doracle.db.url=\\${db.url} package'
}
}
}
}
Now if you see, Jenkins will prepare the maven command like this-
If you don't escape it will give you Bad substitution error
I try to run SonarQube analysis for a Gradle project in a Jenkins Pipeline using the following code:
stage('SonarQube') {
withGradle {
withSonarQubeEnv('SonarQube Env') {
bat "./gradlew sonarqube"
}
}
}
The Gradle plugin is installed in Jenkins but I am getting the following error:
05:15:05 D:\*\*\*\*\*\*>./gradlew sonarqube
05:15:05 '.' is not recognized as an internal or external command,
Two things are incorrect in your code. On Windows machines you have to:
use backslashes instead of slashes in paths (./command → .\command)
execute script written for Windows (gradlew is a Unix script, gradlew.bat is a Windows script)
This code should work:
stage('SonarQube') {
withGradle {
withSonarQubeEnv('SonarQube Env') {
bat '.\\gradlew.bat sonarqube'
}
}
}
Gradle Wtapper by default is provided with two script gardlew and gradlew.bat. If your project doesn't have the gradlew.bat file, execute on your Unix machine ./gradlew wrapper. The missing file will be generated.
Btw. You don't need the Jenkins Gradle plugin, when you use Gradlew Wrapper. The plugin is required when you want to provide Gradle installations for jobs, example:
stage('SonarQube') {
withGradle {
withSonarQubeEnv('SonarQube Env') {
bat "${tool(name: 'toolId', type: 'gradle')}\\bin\\gradle.bat sonarqube"
}
}
}
toolId must much the identifiers used in the Jenkins Global Tool Configuration, examples: gradle-6.X, gradle-6.8.3 etc.
Is there a way to use the Jenkins "Execute system groovy script" step from a pipeline file which is SCM commited ?
If yes, how would I access the predefined variables (like build) in it ?
If no, would I be able to replicate the functionality otherwise, using for example the Shared Library Plugin ?
Thanks !
You can put groovy code in a pipeline in a (always-source-controlled) Jenkinsfile, like this:
pipeline {
agent { label 'docker' }
stages {
stage ('build') {
steps {
script {
// i used a script block because you can jam arbitrary groovy in here
// without being constrained by the declarative Jenkinsfile DSL
def awesomeVar = 'so_true'
print "look at this: ${awesomeVar}"
// accessing a predefined variable:
echo "currentBuild.number: ${currentBuild.number}"
}
}
}
}
}
Produces console log:
[Pipeline] echo
look at this: so_true
[Pipeline] echo
currentBuild.number: 84
Click on the "Pipeline Syntax" link in the left navigation of any of pipeline job to get a bunch of examples of things you can access in the "Global Variables Reference."
I'm trying to migrate my build pipelines to the "Pipeline plugin" using the groovy build scripts.
My pipelines are usually:
Test (gradle)
IntegrationTest (gradle)
Build (gradle)
Publish (artifactory)
I would like to use the gradle variables like version/group etc. in my jenkins build script to publish to the correct folders in artifactory. Something the artifactory plugin would take care of for me in the past. How can this be achieved?
For a single gradle project I use something like this:
node('master')
{
def version = 1.0
def gitUrl = 'some.git'
def projectRoot = ""
def group = "dashboard/frontend/"
def artifactName = "dashboard_ui"
def artifactRepo = "ext-release-local"
stage "git"
git branch: 'develop', poll: true, url: "${gitUrl}"
dir(projectRoot)
{
sh 'chmod +x gradlew'
stage "test"
sh './gradlew clean test'
stage "build"
sh './gradlew build createPom'
stage "artifact"
def server = Artifactory.server('artifactory_dev01')
def uploadSpec = """{
"files": [
{
"pattern": "build/**.jar",
"target": "${artifactRepo}/$group/${artifactName}/${version}/${artifactName}-${version}.jar"
},
{
"pattern": "pom.xml",
"target": "${artifactRepo}/$group/${artifactName}/${version}/${artifactName}.pom"
}
]
}"""
def buildInfo1 = server.upload spec: uploadSpec
server.publishBuildInfo buildInfo1
}
}
For future reference here an example with the more modern declarative pipeline:
pipeline {
agent any
stages {
stage('somestage') {
steps {
script {
def version = sh (
script: "./gradlew properties -q | grep \"version:\" | awk '{print \$2}'",
returnStdout: true
).trim()
sh "echo Building project in version: $version"
}
}
}
}
}

How to do I get the output of a shell command executed using into a variable from Jenkinsfile (groovy)?
I think you actually have two different approaches to tackle this problem :
1. Get version/group from sh script
Find a way to get Gradle version from gradle build tool (e.g. gradle getVersion(), but I'm not familiar with Gradle) and then use shell script to get this version. If Gradle command to get the version is gradle getVersion(), you would do in your pipeline :
def projectVersion = sh script: "gradle getVersion()", returnStdout: true
def projectGroup= sh script: "gradle getGroup()", returnStdout: true
and then just inject your $projectVersion and $projectGroup variables in your current pipeline.
2. Configure your Gradle build script to publish to Artifactory
This is the reverse approach, which I personnaly prefer : instead of giving Artifactory all your Gradle project information, juste give Gradle your Artifactory settings and use Gradle goal to easily publish to Artifactory.
JFrog has a good documentation for this solution in their Working with Gradle section. Basically, you will follow the following steps :
Generate a compliant Gradle build script from Artifactory using Gradle Build Script Generator and include it to your project build script
Use Gradle goal gradle artifactoryPublish to simply publish your current artifact to Artifactory
For others who Google'd their way here, if you have the Pipeline Utility Steps plugin and store what you need in your gradle.properties file, you can do something like this in the environment block:
MY_PROPS = readProperties file:"${WORKSPACE}/gradle.properties"
MY_VERSION = MY_PROPS['version']
