Part 1 - Configure SonarQube Exclusions in Jenkins

We can turn off SonarQube analysis for some code in Jenkins. We do this by setting exclusions in the SonarQube project settings. Here is how we can do it:

  1. Access SonarQube Project Settings:

    • First, we go to the SonarQube dashboard.
    • Next, we find the project where we want to set exclusions.

  2. Set Exclusions:

    • In the project settings, we need to look for the General Settings section.

    • We find Analysis Scope.

    • Now, we add the paths or patterns of the files we want to exclude in the Source File Exclusions field. For example:

      **/test/**, **/generated/**, **/*.spec.js

  3. Save the Changes:

    • After we enter the exclusions, we need to save the changes.

This setup will make sure that SonarQube does not check the specified code when Jenkins runs the build.

For more details on how to configure Jenkins with SonarQube, we can check this guide.

Part 2 - Use SonarQube Analysis Parameters

To turn off Sonar for some code in Jenkins, we can use SonarQube analysis parameters. We need to set the sonar.exclusions property in our Jenkins job or pipeline script. This helps us say which files or folders SonarQube should not check during the analysis.

  1. First, go to the Build Environment section in your Jenkins job settings.
  2. Next, add this line to the SonarQube Scanner command:
-Dsonar.exclusions=**/path/to/your/excluded/files/**,**/another/path/**

Change **/path/to/your/excluded/files/** to the real path you want to skip. We can use wildcards to match many files or folders.

  1. If we are using a Jenkins pipeline script, we can put the exclusion parameter in the withSonarQubeEnv block:
pipeline {
    agent any
    stages {
        stage('SonarQube Analysis') {
            steps {
                script {
                    withSonarQubeEnv('SonarQube') {
                        sh 'mvn clean verify sonar:sonar -Dsonar.exclusions=**/path/to/excluded/**'
                    }
                }
            }
        }
    }
}

This setup turns off SonarQube analysis for the paths we choose. It helps us keep our code quality without checking files we do not want. If we need more details on other settings, we can check how to configure Git post-commit.

Part 3 - Modify the sonar-project.properties File

We can turn off SonarQube analysis for certain code parts by changing the sonar-project.properties file. We do this by adding exclusion patterns. This file is usually in the main folder of our project.

Here is how we can change it:

  1. Open the sonar-project.properties file.
  2. Add these properties to ignore certain files or folders:
# Exclude specific files
sonar.exclusions=**/path/to/excluded/file.java, **/path/to/excluded/directory/**

# Example: Exclude all test files and a specific class
sonar.exclusions=**/*Test.java, **/src/main/java/com/example/ExcludedClass.java
  1. Save the changes.

By using patterns, we can tell SonarQube which files or folders to ignore. For example, if we want to ignore all files in a certain folder or all files with a certain ending, we just change the sonar.exclusions property.

For more details on how to set exclusions in SonarQube, we can check the official SonarQube documentation.

If we need more help with Jenkins setup, we can find helpful info in this article on how to fix Jenkins CI pipeline.

Part 4 - Use Annotations in Code

We can turn off Sonar for certain parts of code in Jenkins by using annotations directly in our code. SonarQube supports different annotations. These can help us exclude some classes, methods, or lines from being checked.

Using Annotations

  • @SuppressWarnings: This is a Java annotation. We can use it to turn off specific warnings. For example:

    @SuppressWarnings("squid:S00100") // Turns off specific Sonar rule
public void myMethod() {
    // Code that we want to ignore from Sonar check
}

  • @SonarIgnore: If we use a language that allows custom annotations, we can make an annotation like this:

    @Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface SonarIgnore {}

    After that, we can add this annotation to the methods we want to ignore:

    @SonarIgnore
public void methodToIgnore() {
    // This method will be ignored by SonarQube
}

More Notes

We need to set up our SonarQube project to recognize these annotations. If we make custom ones, we should check the SonarQube documentation for help on how to manage and set rule exclusions.

For more information on how Jenkins and SonarQube work together, we can look at this guide.

Using annotations in our code is a good way to manage SonarQube checks. This helps our Jenkins pipeline to run well without too many warnings for certain parts of the code.

Part 5 - Set Up Quality Profiles in SonarQube

We can turn off SonarQube analysis for specific code in Jenkins by setting up Quality Profiles in SonarQube. This helps us define rules that we can include or exclude based on what our project needs.

  1. Access SonarQube:

    • First, we need to log in to our SonarQube instance.

  2. Navigate to Quality Profiles:

    • Next, we go to the Quality Profiles section from the main menu.

  3. Create or Modify a Quality Profile:

    • We can create a new profile or change an existing one. Click on Create to make a new profile or select an existing one to edit it.

  4. Select Language:

    • Then, we choose the programming language we want to set up.

  5. Add or Remove Rules:

    • In the profile we selected, we can add or remove specific rules. To exclude some code from analysis:
      • Click on the Activate More Rules button.
      • Search for the rules we want to exclude and turn them off.

  6. Set Exclusions in Quality Profiles:

    • To set exclusions for certain files or folders, we go to the Settings tab of our Quality Profile and set up Source File Exclusions.
    • We can use wildcards for pattern matching. For example, **/excluded-directory/** or **/*.excluded-file.

  7. Apply Quality Profile to Your Project:

    • After we set up the profile, we need to make sure it is applied to our project. We do this by going to project settings and selecting the Quality Profile we want.

By setting up Quality Profiles in SonarQube, we can adjust the analysis to fit our project needs. This way, we can turn off analysis for specific code parts. For more detailed steps on managing Jenkins configurations, you can visit this guide.

Part 6 - Adjust Jenkins Pipeline Script for Exclusions

To turn off Sonar for certain code in our Jenkins pipeline, we can change the Jenkins Pipeline script. We add some parameters to skip files or folders from the SonarQube analysis. We do this using the sonar.exclusions property.

Here is how we change our Jenkins Pipeline script:

  1. Open your Jenkinsfile or pipeline settings.
  2. Find the stage where we set up the SonarQube analysis.
  3. Add the sonar.exclusions parameter in the withSonarQubeEnv block.

Here is a simple Jenkinsfile snippet:

pipeline {
    agent any
    stages {
        stage('SonarQube Analysis') {
            steps {
                script {
                    withSonarQubeEnv('SonarQube') {
                        sh """
                        mvn clean verify sonar:sonar \
                        -Dsonar.projectKey=my-project \
                        -Dsonar.sources=src \
                        -Dsonar.exclusions=**/excluded-directory/**,**/*.test.java
                        """
                    }
                }
            }
        }
    }
}

In this example:

  • We set the sonar.exclusions parameter to skip all files in the excluded-directory and any files that end with .test.java.
  • We can change the exclusions based on our project needs.

This way, we can manage which parts of our code are checked by SonarQube in our Jenkins pipeline. This helps us make sure only important code goes through quality checks.
