Meet "uninitialized constant #::Chef::Resource::CookbookFile" when running chef-client

Question

I am using Chef 11.10.0.

I implement a new resource called MyCookbookFile which inherits Chef::Resource::CookbookFile.

And, I am not going to change the provider this moment (So Chef::Provider::CookbookFile will be used).

require 'chef/resource/cookbook_file'
require 'chef/mixin/securable'

class Chef
  class Resource
    class MyCookbookFile < Chef::Resource::CookbookFile
      include Chef::Mixin::Securable

      provides :my_cookbook_file, :on_platforms => :all

      # more codes here...

    end
  end
end

I met the following error:

================================================================================
Recipe Compile Error in /var/chef/cache/cookbooks/my-cookbook/resources/my_cookbook_file.rb
================================================================================

I tried to print and check the LOAD_PATH in my cookbook. It includes:

/opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef-11.10.0/bin/../lib

And the library should be in place:

[root@localhost /]$ ll /opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef-11.10.0/lib/chef/resource/cookbook_file.rb 
-rw-r--r-- 1 root root 1598 Feb  6 17:22 /opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef-11.10.0/lib/chef/resource/cookbook_file.rb

You should add :: before Chef::Resource::CookbookFile.

 class MyCookbookFile < ::Chef::Resource::CookbookFile

And move your my_cookbook_file.rb to libraries folder of the cookbook, since you use pure Ruby and not LWRP syntax.

Okay. I put inside the *libraries* folder. But when I use the resource in *ANOTHER* cookbook, it gives the following error: `NoMethodError ------------- No resource or method named `my_cookbook_my_cookbook' for `Chef::Recipe "test-recipe"'` My recipe is defined like this: ` my_cookbook_my_cookbook_file "/tmp/my_template" do source "my_template.erb" mode 0644 end` – Simon Ho Feb 18 '14 at 01:43
You must state `depends 'my-cookbook'` in your _other_ cookbook's _metadata.rb_. And it should be just `my_cookbook_file`. – Draco Ater Feb 18 '14 at 08:39

Change:

class MyCookbookFile < Chef::Resource::CookbookFile

to:

class MyCookbookFile < ::Chef::Resource::CookbookFile
