What SonarQube is...

SonarQube is a static code analysis tool that automatically inspects the quality of source code. It’s widely used by development teams to detect errors, security vulnerabilities, bugs, and code smells, and to ensure that certain coding standards are being followed.

🧠 What does SonarQube do?

  1. Analyze source code in multiple languages (Java, JavaScript, Python, C#, etc.).

2. Detects:

  • Bugs (errors that may cause runtime failures).
  • Security vulnerabilities (like injections, unsafe deserialization, etc.).
  • Code smells (bad practices that affect maintainability).
  • Duplicated code.

3. Measures indicators such as:

  • Unit test coverage.
  • Cyclomatic complexity.
  • File, class, and method size.

🛠 How is it used?

  • It can be integrated with tools like:

    • Maven, Gradle, Jenkins, GitHub Actions, GitLab CI, Azure DevOps, etc.

  • It offers a web interface where you can:

    • View detected issues.
    • Navigate through the source code.
    • Configure analysis rules.
    • Define quality gates (thresholds for acceptable quality).

✅ Example usage in Java (with Maven) 

mvn sonar:sonar \
  -Dsonar.projectKey=my-project \
  -Dsonar.host.url=http://localhost:9000 \
  -Dsonar.login=your_authentication_token

🎯 Why use SonarQube?

  • Improves software quality.
  • Reduces technical debt.
  • Increases system security.
  • Automates code reviews in CI/CD pipelines.
