how to specify the pom.xml path in jenkins pipeline script

Question

this is how my script looks like

node {
    stage ('Build') {
        git url: 'https://github.com/rakshitha2/test_proj.git'

        def mvnHome = tool 'M3'

        bat "${mvnHome}\\bin\\mvn -B install"
    }

I'm new to Jenkins and groovy. kindly help me with this.

Answer 1

As it is basically a normal maven mechanism. So

 sh 'mvn -f otherdirectory/pom.xml clean install'

Answer 2

pipeline {
    agent any
    tools {
        maven 'mavenHome'
        jdk 'JavaHome'
    }
    stages {
        stage('Build') {
            steps {
                echo 'maven clean'
                //ABC indicates the folder name where the pom.xml file resides
                bat ' mvn -f ABC/pom.xml clean install'  
            }
            post {
                success {
                    echo 'Now Archiving'
                }
            }
        }
    }
}
