If a PMD static code analysis rule has a priority of 1 and is violated once, what will be the violation score?

The violation score in PMD static code analysis is determined by the priority of the rule and the number of times it has been violated. In PMD, the scoring system works such that the priority of a rule denotes how critical the violation is, with a priority of 1 being the highest.

When a rule with a priority of 1 is violated, the score assigned to this violation is based on the formula which typically follows a pattern that reflects both its priority level and the frequency of the violation. For a priority of 1 violated once, the corresponding violation score is calculated and results in a score of 5.

This scoring implies that the more serious the rule (lower number priority), the higher the impact on the overall score when it is not adhered to. Violations of lower-priority rules (higher numerical values) would consequently produce lower scores for similar issues, thus reflecting a reinforcement of best coding practices by incentivizing the resolution of the most critical issues first.

In summary, a violation of a PMD rule with the highest severity (priority of 1) that occurs once leads to a total violation score of 5, which emphasizes the importance of addressing such violations promptly.
