¶ Integrate Quality and Docker Artefact Management For Maven Projects Using Plug-ins…
In the world of Java development, delivering high-quality, reliable, and easily deployable applications is paramount. To achieve this, integrating robust testing, comprehensive code analysis, and streamlined containerization into your workflow is crucial. This is where the powerful combination of Jacoco, SonarQube, and Jkube comes into play.
- Jacoco, a code coverage library, provides insights into the effectiveness of your tests by highlighting areas of your codebase that lack sufficient test coverage.
- SonarQube, a static code analysis tool, goes beyond test coverage to identify potential bugs, vulnerabilities, code smells, and technical debt, ensuring code maintainability and adherence to best practices.
- Jkube, a Kubernetes-native Java development tool, simplifies the process of containerizing your applications, making deployments smoother and more efficient.

¶ Conclusion
By integrating these three tools, you create a powerful feedback loop that fosters a culture of continuous improvement, leading to higher quality Java applications and a more efficient development process. By using these plugins you can reduce the build / package / code quality time by a significantly. This will also ensure that developer do not check-in before they build and run it locally.
