Question

I have some troubles with Salesforce extension PMD and shows the following message:

Answer 1

Yeah, I also faced these warnings.

I created a started project (java-17, maven, pmd, unit tests, log4j2). https://github.com/yan-khonski-it/java-17-pmd

Instead of using a specific rule, I used category.

<rulesets>
  <ruleset>category/java/bestpractices.xml</ruleset>

  <!-- My own file with custom rules, you can remove it-->
  <ruleset>custom-ruleset.xml</ruleset>
</rulesets>

For example, in the plugin source code:

<!-- Rules, that have been moved into a category -->

and same applies to other categories / rule sets.
