生成SNAPSHOT时不会触发Jenkins Multibranch项目

Question

I have in Jenkins (v2.164.3) different maven projects, which reside in our local gitlab server.

All projects define the following Jenkinsfile :

node {
    stage('git') {
        checkout scm
    }
    stage('compile') {
        withMaven(mavenSettingsConfig: 'e228f408-7768-4374-b8e1-259321e2fa99') {
            bat "mvn clean compile"
        }
    }
    stage('test') {
        withMaven(mavenSettingsConfig: 'e228f408-7768-4374-b8e1-259321e2fa99') {
            bat "mvn test"
        }
    }
    stage('install') {
        withMaven(mavenSettingsConfig: 'e228f408-7768-4374-b8e1-259321e2fa99') {
            bat "mvn install -DskipTests"
        }
    }
}

in the configuration of the multibranch project, the option Build whenever a SNAPSHOT dependency is built is checked. (The same option in the configuration of the several branches is not checked)

Unfortunately this check seems to be ignored in my case, as when a project (projectX) is build (eg the develop branch, that creates a SNAPSHOT jar), all downstream projects (withe their develop branch), that define a dependency in their pom to projectX, are not triggered.

What is wrong ? Or do I need to check the option in all branches of the multibranch project ? Or do I need to change something in my Jenkinsfile ?

Thanks

Please see the Pipeline Maven Plugin FAQ > My downstream pipelines don't get triggered even if I use "Build whenever a SNAPSHOT dependency is built"

To configure the Jenkins Pipeline Maven integration to trigger downstream pipelines on "mvn install":

• Either change the global configuration:

  • Navigate to "Manage Jenkins / Global Tools Configuration"
  • Click on "Add Publisher" and select "Pipeline Graph Publisher"
  • In the section "Downstream Pipeline Triggers", change the the "Maven lifecycle threshold" from "deploy" to "install"

• Or in the script of the upstream pipeline, configure withMaven(options: [pipelineGraphPublisher(lifecycleThreshold: 'install')]) {...}

Note: regarding your declaration mavenSettingsConfig: 'e228f408-...' , please note that you can declare the Maven settings either globally or at the folder level as documented on Jenkins Pipeline Maven Integration > Features > Maven Settings
