Getting Project Version from Maven POM in Jenkins

Question

Is there any way a Jenkins build can be aware of the Maven version number of a project after processing the POM?

I\'ve got some projects where versioning is controll

Answer 1

I used Pipeline Utility Steps plugin in a declarative pipeline job to get Maven version. In the example below I use script variable instead of environment variable, because that can be modified and passed between stages.

def TAG_SELECTOR = "UNINTIALIZED"
pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                sh "mvn --batch-mode -U deploy"
                script {
                    TAG_SELECTOR = readMavenPom().getVersion()
                }
                echo("TAG_SELECTOR=${TAG_SELECTOR}")
            }
        }
    }
}

Note: You must approve the getVersion() method after creating the job in Manage jenkins > In-process Script Approval.
