Jenkins pipeline - edit build name on a build triggered from another pipeline - jenkins-pipeline

I have a Jenkins pipeline, that runs sereval other jobs. Something like
pipeline {
...
stage('Job_1') {
build job: 'job-1', parameters: [
...
string(name: 'BUILD_NAME', value: params.BUILD_NAME),
]
}
stage('Job_2') {
build job: 'job-2', parameters: [
...
string(name: 'BUILD_NAME', value: params.BUILD_NAME),
]
}
and job-1, job-2 being matrixJobs. I would like to set the build names using parameter passed to the parent pipeline. The job-1 looking like
matrixJob('job-1') {
...
parameters {
...
stringParam('BUILD_NAME', "#${BUILD_NUMBER} - x", 'Name for the build')
}
wrappers {
...
buildName("${BUILD_NAME}")
}
steps {
...
}
It seems in matrixJob parameters cannot be used in build name, I get error
ERROR: (job_1.groovy, line 39) No such property: BUILD_NAME for class: javaposse.jobdsl.dsl.helpers.wrapper.WrapperContext
I would like to ask how is it possible to change the build name to add e.g. a product version. Or perhaps if there is another way to achieve this besides passing build name as a parameter.
EDIT:
I worked around this problem using script in parent pipeline. Something like this
stage('Job_1') {
build job: 'job-1', parameters: [
...
]
}
stage('Job_2') {
build job: 'job-2', parameters: [
...
]
}
stage('Set_names') {
def build = jenkins.model.Jenkins.instance.getItem('job-1').lastBuild
if(build.getResult() != hudson.model.Result.SUCCESS) {
build.displayName = params.BUILD_NAME
}
}
no tweaking of child jobs was needed.

Change the parameter values in a Jenkins Pipeline

How to map the parameter values to a different value and then execute it inside the pipeline.
parameters {
choice(name: 'SIMULATION_ID',
choices: 'GatlingDemoblaze\nFrontlineSampleBasic\nGatlingDemoStoreNormalLoadTest',
description: 'Simulations')
}
How to map the value of 'GatlingDemoblaze' to '438740439023874' so that the it will be the latter which goes inside the ${params.SIMULATION_ID}? Can we do this with a simple groovy code?
gatlingFrontLineLauncherStep credentialId: '', simulationId:"${params.SIMULATION_ID}"
Thanks for the help.
As suggested in the comments the best approach will be to use the Extensible Choice Parameter Plugin and define the needed key-value pairs, however if you don't want to use the plugin you can create the mapping using groovy in the pipeline script and use it.
For that you have several options:
If you need it for a single stage you can define the map inside a script block and use it in that stage:
pipeline {
agent any
parameters {
choice(name: 'SIMULATION_ID', description: 'Simulations',
choices: ['GatlingDemoblaze', 'FrontlineSampleBasic', 'GatlingDemoStoreNormalLoadTest'])
}
stages {
stage('Build') {
steps {
script {
def mappings = ['GatlingDemoblaze': '111', 'FrontlineSampleBasic': '222', 'GatlingDemoStoreNormalLoadTest': '333']
gatlingFrontLineLauncherStep credentialId: '', simulationId: mappings[params.SIMULATION_ID]
}
}
}
}
}
You can also define it as a global parameter that will be available in all stages (and then you don't need the script directive):
mappings = ['GatlingDemoblaze': '111', 'FrontlineSampleBasic': '222', 'GatlingDemoStoreNormalLoadTest': '333']
pipeline {
agent any
parameters {
choice(name: 'SIMULATION_ID', description: 'Simulations',
choices: ['GatlingDemoblaze', 'FrontlineSampleBasic', 'GatlingDemoStoreNormalLoadTest'])
}
stages {
stage('Build') {
steps {
gatlingFrontLineLauncherStep credentialId: '', simulationId: mappings[params.SIMULATION_ID]
}
}
}
}
and another options is to set these values in the environment directive:
pipeline {
agent any
parameters {
choice(name: 'SIMULATION_ID', description: 'Simulations',
choices: ['GatlingDemoblaze', 'FrontlineSampleBasic', 'GatlingDemoStoreNormalLoadTest'])
}
environment{
GatlingDemoblaze = '111'
FrontlineSampleBasic = '222'
GatlingDemoStoreNormalLoadTest = '333'
}
stages {
stage('Build') {
steps {
gatlingFrontLineLauncherStep credentialId: '', simulationId: env[params.SIMULATION_ID]
}
}
}
}

How to trigger a multiple run in a single pipeline job of jenkins?

I have a pipeline job which run with below pipeline groovy script,
pipeline {
parameters{
string(name: 'Unique_Number', defaultValue: '', description: 'Enter Unique Number')
}
stages {
stage('Build') {
agent { node { label 'Build' } }
steps {
script {
sh build.sh
}
}
stage('Deploy') {
agent { node { label 'Deploy' } }
steps {
script {
sh deploy.sh
}
}
stage('Test') {
agent { node { label 'Test' } }
steps {
script {
sh test.sh
}
}
}
}
I just trigger this job multiple times with different unique ID number as input parameter. So as a result i will have multiple run/build for this job at different stages.
With this, i need to trigger a multiple run/build to be promote to next stage (i.e., from build to deploy or from deploy to test) in this pipeline job as a one single build instead of triggering each and every single run/build to next stage. Is there any possibility?
I was also trying to do the same thing and found no relevant answers. May this help to someone.
This will read a file that contains the Jenkins Job name and run them iteratively from one single job.
Please change below code accordingly in your Jenkins.
pipeline {
agent any
stages {
stage('Hello') {
steps {
script{
git branch: 'Your Branch name', credentialsId: 'Your crendiatails', url: ' Your BitBucket Repo URL '
##To read file from workspace which will contain the Jenkins Job Name ###
def filePath = readFile "${WORKSPACE}/ Your File Location"
##To read file line by line ###
def lines = filePath.readLines()
##To iterate and run Jenkins Jobs one by one ####
for (line in lines) {
build(job: "$line/branchName",
parameters:
[string(name: 'vertical', value: "${params.vertical}"),
string(name: 'environment', value: "${params.environment}"),
string(name: 'branch', value: "${params.aerdevops_branch}"),
string(name: 'project', value: "${params.host_project}")
]
)
}
}
}
}
}
}
You can start multiple jobs from one pipeline if you run something as:
build job:"One", wait: false
build job:"Two", wait: false
Your main job starts children pipelines and children pipelines will run in parallel.
You can read PipeLine Build Step documentation for more information.
Also, you can read about the parallel run in declarative pipeline
Here you can find a lot of examples for parallel running

How to ask user input only when branch matches master in Jenkinsfile pipeline?

I tried to use the following Jenkinsfile to ask input only on master branch and can't get the groovy grammer pass validation:
pipeline {
stage('Deploy') {
when {
branch 'master'
}
steps {
input(message: "Please input", parameters: [string(name: "VERSION", defaultValue="", description="")]
}
}
}
The error is:
java.lang.IllegalArgumentException: Expected named arguments but got [{name=VERSION, description=""}, null]
I searched a lot but didn't find a single one example about using input step in the Jenkinsfile with parameters.
Can anyone shed some light on this? Thanks in advance!
Finally find a way to do this, we should wrap the input with the script keyword.
stage('Deploy to k8s prod') {
when {
branch 'release-prod'
}
steps {
script {
env.VERSION = input message: '请输入参数', ok: '确定', parameters: [
string(name:'VERSION', description: "版本号")]
}
sh "echo ${env.VERSION}"
}
}
}

How to skip a stage in Jenkinsfile pipeline when pipeline name ends with deliver?

I have 2 pipelines one for review and one for deploy. So when the pipeline ends with review, I want to skip Jenkinsfile execution. However, when it ends with deploy, it should execute the stage or the Jenkinsfile.
I tried to use if, but this is a declarative pipeline, so when should be used. I want to avoid execution of stage using when condition if I encounter deploy pipeline end.
#!/usr/bin/env groovy
final boolean Deploy = (env.JOB_NAME as String).endsWith("-deploy")
pipeline {
agent any
parameters {
choice(
choices: ['greeting' , 'silence'],
description: '',
name: 'REQUESTED_ACTION')
}
stages {
//how to ouse when here to use deploy vairable to avoide execution of stage below
stage ('Speak') {
steps {
echo "Hello, bitwiseman!"
}
}
}
}
You can skip stages in declarative pipelines using when, so the following should work.
stages {
stage('Deploy') {
when { equals expected: true, actual: Deploy }
steps {
// ...
}
}
}
An alternative to #StephenKing’s answer, which is also correct, you can rewrite the when block when evaluating Booleans as follows:
stages {
stage('Deploy') {
when {
expression {
return Deploy
}
}
steps {
echo "Hello, bitwiseman!" // Step executes only when Deploy is true
}
}
}
This will execute the stage Deploy only when the variable Deploy evaluates to true, else the stage will be skipped.
I've got quite a hard time to find it too, but finally:
stage('Speak') {
when {
expression { params.REQUESTED_ACTION != 'SILENCE' }
}
steps {
echo "Hello, bitwiseman!"
}
}
Jenkins docs with examples here: https://jenkins.io/doc/book/pipeline/syntax/#when-example
Here is an example for a Jenkins scripted pipeline:
stage('Input of Scratch instance and Access token') {
timeout(time: 60, unit: 'SECONDS') {
script {
try {
env.SCRATCH_INSTANCE_URL = input message: 'Please enter the SCRATCH_INSTANCE_URL',
parameters: [string(defaultValue: '',
description: '',
name: 'SCRATCH_INSTANCE_URL')]
env.SCRATCH_ACCESS_TOKEN = input message: 'Please enter the SCRATCH_ACCESS_TOKEN',
parameters: [string(defaultValue: '',
description: '',
name: 'SCRATCH_ACCESS_TOKEN')]
} catch (Throwable e) {
echo "Caught ${e.toString()}"
currentBuild.result = "SUCCESS"
}
}
}
}
// -------------------------------------------------------------------------
// Logout from Dev Hub.
// -------------------------------------------------------------------------
stage('Logout from DevHub') {
if (env.SCRATCH_INSTANCE_URL == null) {
rc = command '''export SFDX_USE_GENERIC_UNIX_KEYCHAIN=true
sfdx force:auth:logout --targetusername ${DEV_HUB_USERNAME} -p
echo ${SCRATCH_INSTANCE_URL}
echo ${SCRATCH_ACCESS_TOKEN}
'''
} else {
echo "Skipping this stage"
}
}
Even you can skip some parts of the steps using below code. Let's say REQUIRED_UPLOAD_INSTALL is a parameter.
stage('Checking Mail List') {
steps {
script {
if(!(env.REQUIRED_UPLOAD_INSTALL.toBoolean())) {
env.mail_list = 'test#testg.com'
}
}
}
}
But it doesn't support in post steps, not even in the when syntax.

How to define jenkins build trigger in jenkinsfile to start build after other job

I would like to define a build trigger in my Jenkinsfile. I know how to do it for the BuildDiscarderProperty:
properties([[$class: 'jenkins.model.BuildDiscarderProperty', strategy: [$class: 'LogRotator', numToKeepStr: '50', artifactNumToKeepStr: '20']]])
How can I set the Build Trigger that starts the job, when another project has been built. I cannot find a suitable entry in the Java API docs.
Edit:
My solution is to use the following code:
stage('Build Agent'){
if (env.BRANCH_NAME == 'develop') {
try {
// try to start subsequent job, but don't wait for it to finish
build job: '../Agent/develop', wait: false
} catch(Exception ex) {
echo "An error occurred while building the agent."
}
}
if (env.BRANCH_NAME == 'master') {
// start subsequent job and wait for it to finish
build '../Agent/master', wait: true
}
}
I just looked for the same thing and found this Jenkinsfilein jenkins-infra/jenkins.io
In short:
properties([
pipelineTriggers([cron('H/30 * * * *')])
])
This is an example:
#Project test1
pipeline {
agent {
any
}
stages {
stage('hello') {
steps {
container('dind') {
sh """
echo "Hello world!"
"""
}
}
}
}
post {
success{
build propagate: false, job: 'test2'
}
}
}
post {} will be execute when project test1 is built and the code inside
success {} will only be executed when project test1 is successful.
build propagate: false, job: 'test2' will call project test2.
propogate: false ensures that project test1 does not wait for project test2's
completion and simply invokes it.
