Jenkins Pipeline code for running scan in SonarQube

node {

    def mvnHome = tool 'Maven3'
    stage ("checkout")  {
        //write pipeline code
    }

   stage ('build')  {
    sh "${mvnHome}/bin/mvn clean install -f MyWebApp/pom.xml"
    }

     stage ('Code Quality scan')  {
       withSonarQubeEnv('SonarQube') {
