I tried putting the config.include AllureRSpec::Adaptor in both spec_helper.rb and rails_helper.rb. When I try to run rspec spec\models, it runs successfully, outputting xml data. When I try to use one of the rake tasks, i.e. rake spec:models, it fails with the following error:

NameError: uninitialized constant RSpec::Support
/Users/timothy/.rvm/gems/ruby-2.1.0@skillet/gems/rspec-core-3.3.2/lib/rspec/core/formatters/base_formatter.rb:1:in `<top (required)>'
/Users/timothy/.rvm/gems/ruby-2.1.0@skillet/gems/allure-rspec-0.7.4/lib/allure-rspec/formatter.rb:1:in `<top (required)>'
/Users/timothy/.rvm/gems/ruby-2.1.0@skillet/gems/allure-rspec-0.7.4/lib/allure-rspec.rb:3:in `<top (required)>'

Looking into this, it seems to be trying to load a specific formatter before RSpec::Core has been loaded.

I'm running RSpec 3.3.0 and Rails 4.1.13. What am I doing wrong? Let me know if you need any more information.
