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

Question

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!"
}
}
}
}

Answer 1

You can skip stages in declarative pipelines using when, so the following should work.
stages {
stage('Deploy') {
when { equals expected: true, actual: Deploy }
steps {
// ...
}
}
}

Answer 2

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!"
}
}

Answer 4

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"
}
}

Answer 5

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.
