First, you need SonarQube server 6.2+. In your Jenkins instance, install the latest version of the SonarQube Scanner for Jenkins (2.6.1+). You should, of course, configure in Jenkins administration section the credentials to connect to the SonarQube server.

In your SonarQube server administration page, add a webhook entry:

https://<your Jenkins instance>/sonarqube-webhook/

Now you can configure a pipeline job using the two SonarQube keywords ‘withSonarQubeEnv’ and ‘waitForQualityGate’.

The first one should wrap the execution of the scanner (that will occupy an executor) and the second one will ‘pause’ the pipeline in a very light way, waiting for the webhook payload.

node {
  stage('SCM') {
    git 'https://github.com/foo/bar.git'
  }
  stage('build & SonarQube Scan') {
    withSonarQubeEnv('My SonarQube Server') {
      sh 'mvn clean package sonar:sonar'
    } // SonarQube taskId is automatically attached to the pipeline context
  }
}
 
// No need to occupy a node
stage("Quality Gate") {
  timeout(time: 1, unit: 'HOURS') { // Just in case something goes wrong, pipeline will be killed after a timeout
    def qg = waitForQualityGate() // Reuse taskId previously collected by withSonarQubeEnv
    if (qg.status != 'OK') {
      error "Pipeline aborted due to quality gate failure: ${qg.status}"
    }
  }
}
