在 jenkins 管道上找不到 mvn 命令

Question

I am really new with Jenkins and maven projects and starting to drive me crazy even with a simple sample project using https://github.com/jglick/simple-maven-project-with-tests.git

Also using the Pipeline sample script GitHub + Maven from Jenkins

stages {
      stage('Build') {
         steps {
            // Get some code from a GitHub repository
            git 'https://github.com/jglick/simple-maven-project-with-tests.git'

            // Run Maven on a Unix agent.
            sh "mvn -Dmaven.test.failure.ignore=true clean package"

But i'm getting the next error:

+ mvn -version
/var/lib/jenkins/workspace/app-maven@tmp/durable-dba02bb4/script.sh: line 1: mvn: command not found

I found an article which says to use this method for save the mvn path on a variable and use it:

steps {
    // Get some code from a GitHub repository
    git 'https://github.com/alvarosjf/maven-app.git'

    // Run Maven on a Unix agent.
    def mvnHome = tool name: '3.6.3', type: 'maven'
    sh "${mvnHome}/bin/mvn -version"
    //sh 'mvn -version'

But this is even worst showing an error at the startup

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 5: Not a valid stage section definition: "def mvnHome = tool name: '3.6.3', type: 'maven'". Some extra configuration is required. @ line 5, column 7.
         stage('Build') {
         ^

1 error

Any trick to try and use a simple jenkins pipeline with Github webhooks + maven?

Answer 1

your pipeline code seems to be correct, but you need the used tool (in your script, maven in version 3.6.3) to be configured within Jenkins itself.

This can be done via:

"Manage Jenkins -> Configure Tools", within the maven section, add a new instance (choose any name you want, use this name also in your pipeline script tool name: 'your-name' type: 'maven' ) leave the rest as it is, which will install maven automatically via downloading from apache servers
