[chef] ERROR: Cookbook app_test not found

["Flores, Luis Fernando (GE Capital, Non-GE)" < >]

Hello master Chefs,

I am testing a cookbook app_test with a Vagrant virtual box VM; when I do 
'vagrant up' at the cookbook location, I get this message:

[2014-08-21T15:46:42-04:00] ERROR: Cookbook app_test not found. If you're 
loading app_test from another cookbook, make sure you configure the 
dependency in your metadata

I notice that at the start of the run, vagrant sends this message:
[application_box] The cookbook path 
'/Users/luis.flores/chef_repo/cookbooks/app_test/cookbooks' doesn't exist. 
Ignoring…

My knife.rb states the cookbook path as ..
cookbook_path            "#{ENV['HOME']}/chef_repo"  # I have tried with  
"#{ENV['HOME']}/chef_repo/cookbooks" with same result

As you can see, the last "/cookbooks" is being added in runtime, I have 
checked my Vagrantfile, metadata.rb and kitchen.yml and none has a cookbook 
path to add. I don't know which component is adding that reference, all I 
know is the 'knife.rb' file should specify that value, so… What is happening?

Regards.
