by Alex Johnson 50 views

Introduction

In this article, we'll walk through the process of re-enabling the SonarGitHub workflow for your project. If you've encountered issues like the workflow failing due to the project not being found, it's likely that you need to configure the sonar.projectKey properly. We'll explore the common causes of this problem and provide a step-by-step guide to resolve it, ensuring your code analysis runs smoothly.

Understanding the Issue

When integrating SonarCloud with your GitHub repository, the workflow relies on specific properties to identify and analyze your project. The error message Project not found. Please check the 'sonar.projectKey' and 'sonar.organization' properties, the 'SONAR_TOKEN' environment variable, or contact the project administrator to check the permissions of the user the token belongs to indicates that SonarCloud can't find the project you're trying to analyze. This can happen for several reasons:

  • Incorrect sonar.projectKey: The project key in your Gradle configuration or SonarCloud configuration doesn't match the actual project key in SonarCloud.
  • Incorrect sonar.organization: The organization key is not correctly set, leading SonarCloud to look in the wrong place.
  • Invalid SONAR_TOKEN: The token used for authentication doesn't have the necessary permissions, or it's simply incorrect.
  • Missing Permissions: The user associated with the token doesn't have the required permissions to access the project in SonarCloud.

To address this, we need to ensure that the sonar.projectKey and sonar.organization properties are correctly configured, the SONAR_TOKEN is valid, and the token has the necessary permissions. Let’s dive into how to resolve these issues.

Step-by-Step Guide to Re-enabling SonarGitHub Workflow

1. Verify SonarCloud Project Key and Organization

First, log in to your SonarCloud account and navigate to the project you want to analyze. In the project settings, you'll find the sonar.projectKey and sonar.organization values. Make sure these values are exactly the same as what you have configured in your Gradle build script or GitHub Actions workflow.

  • Go to your SonarCloud dashboard.
  • Select the project you are configuring.
  • Navigate to Project Settings.
  • Find the Project Key and Organization values. These are case-sensitive, so ensure they match exactly.

These values are crucial for SonarCloud to identify the correct project for analysis. Any discrepancy here will lead to the 'Project not found' error. It’s also a good idea to document these values in a secure location for future reference.

2. Configure sonar.projectKey and sonar.organization in gradle.properties

If you're using Gradle, you can configure the sonar.projectKey and sonar.organization in your gradle.properties file. This ensures that these values are automatically picked up during the SonarQube analysis. Add the following lines to your gradle.properties file:

sonar.projectKey=your_project_key
sonar.organization=your_organization_key

Replace your_project_key and your_organization_key with the actual values from your SonarCloud project settings. By defining these properties in gradle.properties, you ensure that they are consistently applied across all Gradle tasks. This also centralizes the configuration, making it easier to manage and update in the future. It is highly recommended to keep this file secure and not commit it to version control if it contains sensitive information.

3. Set SONAR_TOKEN as a GitHub Secret

To authenticate with SonarCloud, you need to set the SONAR_TOKEN as a GitHub secret. This token should have the necessary permissions to analyze your project.

  • Go to your GitHub repository.
  • Navigate to Settings > Secrets > Actions.
  • Click New repository secret.
  • Set the name to SONAR_TOKEN and the value to your SonarCloud token.
  • Click Add secret.

Ensure that the token you're using has the required permissions. Typically, a token with the 'scan' permission is sufficient. Also, make sure that the token is associated with a user who has access to the SonarCloud project. It's crucial to regularly review and rotate your tokens to maintain security.

4. Update GitHub Actions Workflow

Now, update your GitHub Actions workflow file (.github/workflows/sonar.yml) to use the SONAR_TOKEN secret. Here’s an example of how to configure your workflow file:

name: Sonar
on:
  push:
    branches:
      - main
      - snapshot
  pull_request:
    types: [opened, synchronize, reopened]
jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0  # Shallow clones should be disabled for a better relevancy of analysis
      - name: Set up JDK 17
        uses: actions/setup-java@v4
        with:
          java-version: 17
          distribution: temurin
      - name: Cache SonarCloud packages
        uses: actions/cache@v4
        with:
          path: ~/.sonar/cache
          key: ${{ runner.os }}-sonar
          restore-keys: ${{ runner.os }}-sonar
      - name: Cache Gradle packages
        uses: actions/cache@v4
        with:
          path: ~/.gradle/caches
          key: ${{ runner.os }}-gradle-${{ hashFiles('**/*.gradle') }}
          restore-keys: ${{ runner.os }}-gradle
      - name: Build and analyze
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}  # Needed to get PR information, if any
          SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}
        run: ./gradlew build sonar --info

This workflow checks out the code, sets up JDK 17, caches SonarCloud and Gradle packages, and then builds and analyzes the project using Gradle. The SONAR_TOKEN is passed as an environment variable, allowing the SonarQube analysis to authenticate with SonarCloud. Make sure the fetch-depth: 0 is set to ensure a better relevancy of analysis. The use of caching can significantly speed up the workflow by reusing previously downloaded dependencies and SonarCloud packages.

5. Configure SonarQube in build.gradle

To ensure that the SonarQube analysis runs correctly, you may need to configure it in your build.gradle file. Here’s an example of how to configure SonarQube in your build.gradle file:

plugins {
    id "org.sonarqube" version "4.0.0.2929"
}

sonarqube {
  properties {
    property "sonar.projectKey", "your_project_key"
    property "sonar.organization", "your_organization_key"
    property "sonar.host.url", "https://sonarcloud.io"
    property "sonar.sourceEncoding", "UTF-8"
  }
}

Replace your_project_key and your_organization_key with the actual values from your SonarCloud project settings. This configuration ensures that the SonarQube plugin is properly configured with the necessary properties. The sonar.host.url property specifies the URL of your SonarCloud instance, and the sonar.sourceEncoding property sets the character encoding for the analysis. Ensuring these properties are correctly configured is vital for accurate analysis results.

6. Test the Workflow

After configuring the sonar.projectKey, sonar.organization, and SONAR_TOKEN, it’s time to test the workflow. Push a commit to your main or snapshot branch, or create a new pull request. This will trigger the GitHub Actions workflow, and you should see the SonarQube analysis running. Monitor the workflow logs for any errors.

  • Check the GitHub Actions tab in your repository.
  • Find the Sonar workflow run.
  • Examine the logs for any errors or warnings.

If the workflow runs successfully, you should see the analysis results in your SonarCloud project. If there are any errors, review the logs and double-check your configuration. Common issues include incorrect project keys, invalid tokens, and missing permissions. Addressing these issues promptly will ensure that your SonarQube analysis runs smoothly and provides valuable insights into your code quality.

Troubleshooting Common Issues

  • Project Not Found: Double-check the sonar.projectKey and sonar.organization values in your gradle.properties and build.gradle files. Ensure they match the values in your SonarCloud project settings.
  • Unauthorized: Verify that the SONAR_TOKEN has the necessary permissions to analyze your project. The token should have at least the 'scan' permission.
  • Workflow Failing: Examine the workflow logs for any error messages. Common issues include incorrect configuration, missing dependencies, and network connectivity problems.
  • Analysis Not Showing Up: Ensure that the analysis is being triggered by a push to the correct branch or a pull request. Check the SonarCloud project settings to confirm that the analysis is configured correctly.

By systematically addressing these common issues, you can quickly identify and resolve problems with your SonarQube analysis. Regular monitoring of your workflow and SonarCloud project will help you maintain a high level of code quality and prevent future issues.

Conclusion

Re-enabling the SonarGitHub workflow involves verifying and configuring the sonar.projectKey, sonar.organization, and SONAR_TOKEN. By following this guide, you can ensure that your SonarQube analysis runs smoothly and provides valuable insights into your code quality. Remember to regularly review your configuration and monitor your workflow to prevent future issues.
