It might be a configuration problem, or a problem with hidden dirs...
In my CI, the gems are installed in a .gems directory at the root of the project. I can't seem to be able to exclude that directory...
For example, I get the following:
6% /builds/golf/site/.gems/ruby/2.2.0/gems/activesupport-4.2.6/lib/active_support/core_ext/thread.rb
I tried adding .gems and builds/golf/site/.gems to the exclusions, without success...
Any idea would be welcomed!
