Hi,
I'm not aware of any plugins wrapping those tools.
Instead, I would urge you to take a look at the functionality offered by the
existing analyzers. Additionally, there are some
other plugins (YMMV) which you won't find in the Update Center, but which can be downloaded and installed manually.
And just to clarify, the Checkstyle plugin is not "provided by" SonarQube, but by the folks behind Checkstyle itself.
