SonarQube Quality Gate fix

• Configure the Webhook in sonarqube
• Webhook url http://<jenkins-url>:<port>/sonarqube-webhook
• Now navigate to jenkins -> Configure System -> SonarQube -> Advanced
• Now create a jenkinsfile as shown below

pipeline {
    agent { label 'jdk11-mvn3.8.4' }
    triggers { 
        cron('45 23 * * 1-5')
        pollSCM('*/5 * * * *')
    }
	tools {
		maven 'MVN_3.8.4'
	}
    stages {
        stage('scm') {
            steps {
               
                git url: 'https://github.com/GitPracticeRepo/spring-petclinic.git', branch: 'main'
            }
        }
        stage('build') {
            steps {
                withSonarQubeEnv(installationName: 'SONAR_9.2.1') {
                    sh "mvn clean package sonar:sonar"                                  
                }
            }
        }
		stage("Quality Gate") {
            steps {
                timeout(time: 1, unit: 'HOURS') {
                    // Parameter indicates whether to set pipeline to UNSTABLE if Quality Gate fails
                    // true = set pipeline to UNSTABLE, false = don't
                    waitForQualityGate abortPipeline: true
                }
            }
        }
    }
}

• To view the Jenkinsfile Refer Here

Pushing artifacts to artifactory

• Using declarative pipelines Refer Here for official docs and Refer Here for the official docs of scripted
• Refer Here for the github repository with the project examples to work with artifactory
• Now we will be building the pipeline for our spring petclinic project based on the example Refer Here
• Refer Here for the jenkinsfile created by us to push the artifacts to artifactory server.
• To Download the jar/war/any file from artifactory
  • ansible Refer Here
  • curl Refer Here

Stash and unstash example

• Stash and unstash steps in jenkins will help copying files or directories from one node to other
• Consider a scenario, where you are build a project after build is success you need to deploy on to the test server
  • Here build server is a different and test server is a different node
  • We can use stash to copy the file(s) from one node and paste to the nodes using unstash
