== Ex 1: Using Global Tools Configuration

[source,groovy]

#!groovy

pipeline { agent any

tools {
    maven "3.6.0" // You need to add a maven with name "3.6.0" in the Global Tools Configuration page
}

stages {
    stage("Build") {
        steps {
            sh "mvn -version"
            sh "mvn clean install"
        }
    }
}

post {
    always {
        cleanWs()
    }
}

}

== Ex 2: Using docker agent and official Maven docker image

[source,groovy]

#!groovy

pipeline { environment { JAVA_TOOL_OPTIONS = "-Duser.home=/var/maven" } agent { docker { image "maven:3.6.0-jdk-13" label "docker" args "-v /tmp/maven:/var/maven/.m2 -e MAVEN_CONFIG=/var/maven/.m2" } }

stages {
    stage("Build") {
        steps {
            sh "mvn -version"
            sh "mvn clean install"
        }
    }
}

post {
    always {
        cleanWs()
    }
}

}

== Ex 2: Using dockerfile agent and Maven docker image build from the official image

[source,groovy]

#!groovy

pipeline { environment { JAVA_TOOL_OPTIONS = "-Duser.home=/home/jenkins" } agent { dockerfile { label "docker" args "-v /tmp/maven:/home/jenkins/.m2 -e MAVEN_CONFIG=/home/jenkins/.m2" } }

stages {
    stage("Build") {
        steps {
            sh "ssh -V"
            sh "mvn -version"
            sh "mvn clean install"
        }
    }
}

post {
    always {
        cleanWs()
    }
}
