Make PMD depend on compiled .class files (#2778)

* Revert "Fix spurious PMD warnings when building with —-profile."

This reverts commit cc4bb16.

* Make PMD depend on compiled .class files so type resolution can do its job.

* Make FindBugs depend on compiled .class files via specific task and dynamic value
