Jenkins

Jenkins is a self-contained, open-source server that automates software-related tasks including building, testing, and deploying software. This section explains how you can configure Qodana Docker images in Jenkins Multibranch Pipelines

Prepare your project

Make sure that these plugins are installed on your Jenkins instance:

Docker and Docker Pipeline are required for running Docker images
git is required for git operations in Jenkins projects

Make sure that Docker is installed and accessible to Jenkins.

If applicable, make sure that Docker is accessible to the jenkins user as described in the Manage Docker as a non-root user section of the Docker documentation.

Create a Multibranch Pipeline project as described on the Jenkins documentation portal.

In the root directory of your project repository, create the Jenkinsfile. This file will contain Jenkins configuration scripts described in this section.

Basic configuration

This is the basic configuration of the Jenkins Pipeline.

pipeline {
    environment {
        QODANA_TOKEN=credentials('qodana-token')
    }
    agent {
        docker {
            args '''
              -v "${WORKSPACE}":/data/project
              --entrypoint=""
              '''
            image 'jetbrains/qodana-<linter>'
        }
    }
    stages {
        stage('Qodana') {
            steps {
                sh '''qodana'''
            }
        }
    }
}

In this configuration, the environment block defines the QODANA_TOKEN variable to invoke the project token generated in Qodana Cloud and contained in the qodana-token global credentials. The project token is required by the paid Qodana linters, and is optional for using with the Community linters. You can see these sections to learn how to generate the project token in Qodana Cloud:

The project setup section explains how to get the project token generated while first working with Qodana Cloud
The Manage a project section explains how to create a project in the existing Qodana Cloud organization

This configuration uses the docker agent to invoke Qodana Docker images. Using the WORKSPACE variable, the args block mounts the local checkout directory to the project directory of a Docker image, and image specifies the Docker image invoked.

The stage block calls Qodana. Here, you can also specify the options you would like to configure Qodana with like the quality gate and baseline features.

Analyze specific branches

Using the when block, you can tell Qodana which branches of your project to analyze. For example, this configuration lets you analyze only the feature branch.

pipeline {
    environment {
        QODANA_TOKEN=credentials('qodana-token')
    }
   agent {
      docker {
         args '''
              -v "${WORKSPACE}":/data/project
              --entrypoint=""
              '''
         image 'jetbrains/qodana-<linter>'
      }
   }
   stages {
      stage('Qodana') {
         when {
            branch 'feature'
         }
         steps {
            sh '''qodana'''
         }
      }
   }    
}

You can analyze pull requests as described in the Supporting Pull Requests section of the Jenkins documentation.

Quality gate and baseline

This configuration invokes the quality gate and baseline features using the --fail-threshold <number> and --baseline <path/to/qodana.sarif.json> lines specified in the steps block.

pipeline {
    environment {
        QODANA_TOKEN=credentials('qodana-token')
    }
    agent {
        docker {
            args '''
              -v "${WORKSPACE}":/data/project
              --entrypoint=""
              '''
            image 'jetbrains/qodana-<linter>'
        }
    }
    stages {
        stage('Qodana') {
            steps {
                sh '''
                qodana \
                --fail-threshold <number> \
                --baseline <path/to/qodana.sarif.json>
                '''
            }
        }
    }
}
