Jenkins Sonar quality gates integration via shared library

qualityGates.groovy

#!/usr/bin/env groovy

/**
 * Fails the pipeline if project quality doesn't meet the configured quality profile (see https://docs.sonarqube.org/display/SONAR/Quality+Gates AND https://docs.sonarqube.org/display/SONAR/Quality+Profiles).
 * This DSL function must be invoked after the quality analisys has been published. Example:
 *
 * stage('sonar') { 
 *     steps {
 *         withSonarQubeEnv('sonar') { //there must be a tool named 'sonar' configured on Jenkins (/jenkins/configureTools) 
 *            sh 'mvn sonar:sonar' //publish project quality on sonar
 *        }
 *     }
 * }
 *
 * stage('quality-gates') {
 *     steps {
 *         qualityGates() //this stage will fail if project quality doesn't meet its quality profile
 *     }
 * }
 *
