        stage('test') {
            sh 'echo hello'
        }
        stage('learning') {
            git url: 'https://github.com/GitPracticeRepo/game-of-life.git',
                branch: 'master'
        }

    catch(err) {
        mail subject: "Build Failed for Jenkins JOB $env.JOB_NAME with Build ID $env.BUILD_ID", 
                  body: "Build Failed for Jenkins JOB $env.JOB_NAME", 
                  to: 'qtdevops@gmail.com'
    }
    finally {

Static Code Analysis And Quality Gates

• For every commit it is difficult & time consuming to review the code manually on application features, language best practices, code coverage (unit test imporovements) etc..
• Static Code Analysis tools can scan the code for
  • Language Best Practices
  • Code Coverage
  • Design issues
  • Security Issues (SAST, SCA)
• Sonarqube is the tool which can perform static code analysis.
• If you want your ci/cd pipeline to consider build as failure if the report from static code analysis is not ok/ not meeting your organization criteria, then we need to implement Quality Gate.

Package Repository or Artifact Repository

• During CI/CD we build packages. If we want to store these packages in some repository so that we can deploy any version on our Dev, QA, UAT, PROD environments
• There are lot of options here, But JFrog/Artifactory is widely adopted Refer Here
• The other options are
  • Nexus
  • GitHub Packages
  • Azure Artifacts (Azure DevOps)
