Which of the following tools can be used for static code analysis in MuleSoft?

SonarQube is the tool specifically designed for static code analysis and is widely used in the software development industry. It analyzes the quality of code, identifies bugs, vulnerabilities, and code smells, and provides a detailed report on various code metrics. This is essential in ensuring that the code adheres to the best practices and standards, improving maintainability and reducing technical debt over time.

In the context of MuleSoft, integrating SonarQube into the development pipeline can help developers monitor the quality of their Mule applications, ensuring they are writing clean, efficient, and more secure code. By leveraging SonarQube, teams can proactively address issues during the development phase instead of discovering them later in the deployment or production stage, which can be more time-consuming and costly to fix.

The other tools mentioned, while valuable in their respective areas, do not primarily focus on static code analysis. Jenkins and Travis CI are primarily continuous integration tools that can facilitate the automation of building and testing code but do not provide specific functionalities for analyzing code quality. GitHub Actions, similarly, is a workflow automation tool that can help in continuous integration and deployment processes but lacks the specific static code analysis capabilities that SonarQube offers.
