The plugin logs - for my taste - a little bit too verbose that it doesn't have do anything:

10:15:40 [debug] execute contextualize

I.e. it seems to log for each mojo execution - after the 1st - on each module that it doesn't have to do anything anymore.
Could you remove these please as they IMHO only unnecessary inflate the build console?
