Jenkinsfile - a way to skip the whole pipeline? - jenkins-pipeline

Question

I use the declarative syntax for developing the (multibranch) pipeline script and I'm looking for a way to skip the whole pipeline based on some condition, without having to modify the when on every single stage.
Current use case: I'm setting up a cron to trigger builds at night, but I only want let's say the branches release/v1 and develop to go through the pipeline at night, not the dozen of other branches.
triggers {
cron('H 21 * * 1-5')
}
// SKIP PIPELINE if triggered by timer AND branch not 'release/v1' OR 'develop'
stages {
stage('build') {
when { ... }
}
stage('UT') {
when { ... }
}
etc...
}
any hints would be appreciated.

Answer 1

You can nest stages, if you have the pipeline-definition-plugin 1.3 or later (changelog).
Using that, you can nest your whole job in a parent stage, and use a when directive on the parent stage. All child stages will be skipped if the parent stage is skipped. Here is an example:
pipeline {
agent any
stages {
stage('Parent') {
when {
//...
}
stages {
stage('build') {
steps {
//..
}
}
stage('UT') {
steps {
//...
}
}
}
}
}
}

Answer 2

You can use the SCM Skip plugin. Then use it in the pipeline like so:
scmSkip(deleteBuild: true, skipPattern:'.*#skip-ci.*')
This also enables to delete the build and also use a regex expression easily. The problem is, it aborts the next builds, and then ignores them for the relevant PR if you're connected with GitHub organization.
