Thor source paths for template method
===

I'm trying use Thor template method. But when I wrote spec for my case, it turns out that script didn't see templates directory

### Directory structure
    /crx
      /lib
        /templates
          manifest
        command.rb

### Thor task implementation inside command.rb
    module Crx
      class Command < Thor
        include Thor::Actions

        def self.source_root
          File.dirname(__FILE__)
        end

        desc "add", "add extension files like manifest, content_script"
        def add(name)
          template 'templates/manifest'
        end

      end
    end

### Failed spec

    Crx::Command should create manifest
      Thor::Error:
        Could not find "templates/manifest" in any of your source paths. Your current source paths are: 
        /home/lewy/Programowanie/ruby/crx/lib/crx
