When run on MediaWiki's codebase, doxygen outputs copious warnings about functions/classes/etc. missing documentation altogether, wrong doxygen syntax, and function arguments defined, but undocumented or documented, but not defined.
It would be nice if these could be included in Jenkins a) to guide some developers' love to this and b) to see its development over time. There is a "Doxygen Plugin" but it just seems to provide some links to the documentation instead of parsing the doxygen log. The "Warnings Plugin" on the other hand claims to support doxygen. I think it would be useful if the output looked similar to the PMD warnings (or were integrated there).
