What priority is set for a PMD static code analysis rule if its violation score is 2?

The correct priority for a PMD static code analysis rule with a violation score of 2 is indeed 4. In PMD, the violation scores are categorized into different priorities, with lower scores indicating higher severity and thus a higher priority number assigned. Specifically, a score of 0 is the most severe and corresponds to a priority of 1, while a score of 2 indicates a lower severity, leading to a corresponding priority of 4.

This system of prioritization is crucial because it helps developers determine which issues to address first based on their potential impact on the code quality and overall system reliability. Higher priority numbers signify less critical issues that may not require immediate attention, allowing teams to focus their efforts on more severe problems first. This context is essential in effectively managing technical debt and maintaining clean, efficient code.
