Review Comment:
Yes, they are still supported. But true, it's questionable, how useful these
are. We could thin out the list and keep only 8, 11, 17, 21 and refer to
https://docs.pmd-code.org/latest/pmd_languages_java.html for the full list.
> Upgrade to use PMD 7.0.0 by default
> -----------------------------------
>
> Key: MPMD-379
> URL: https://issues.apache.org/jira/browse/MPMD-379
> Project: Maven PMD Plugin
> Issue Type: Improvement
> Components: CPD, PMD
> Reporter: Andreas Dangel
> Assignee: Andreas Dangel
> Priority: Major
> Fix For: next-release
>
>
> Add support for the new major version of PMD.
> This gives support for analyzing Java 21 code.
> The upgrade from PMD 6 to PMD 7 is a major upgrade, that might impact
> end-users, if they use custom rulesets (see
> [https://maven.apache.org/plugins/maven-pmd-plugin/examples/usingRuleSets.html])
> or if they override the dependencies to upgrade PMD at runtime and currently
> use PMD 6.x (see
> [https://maven.apache.org/plugins/maven-pmd-plugin/examples/upgrading-PMD-at-runtime.html]).
>
> Most likely, end-users have to review their rulesets and migrate them to PMD
> 7. Rules might have been renamed or replaced. See
> [https://docs.pmd-code.org/latest/pmd_release_notes_pmd7.html] and
> [https://docs.pmd-code.org/latest/pmd_userdocs_migrating_to_pmd7.html] .
