upload.a.yaml.for.cap.rb

Capistrano::Configuration.instance.load do

  namespace :deploy do

    namespace :amee do

      namespace :ss3 do

        desc "[internal] Copies ss3.yml file to app servers"
        task :upload, :except => { :no_release => true } do
          ss3_path = Rails.root.join("config", "ss3.yml")
          # this errors out like so:
          # gems/capistrano-2.11.2/lib/capistrano/configuration/namespaces.rb:110:in `block in define_task': wrong number of arguments (2 for 0) (ArgumentError)
          upload (ss3_path), "#{shared_path}/config/ss3.yml"
          # this works
          put (File.read(ss3_path)), "#{shared_path}/config/ss3.yml"
        end

        desc "[internal] Updates the symlink for ss3.yml to the just deployed release."
        task :symlink, :except => { :no_release => true } do
          run "ln -nfs #{shared_path}/config/ss3.yml #{release_path}/config/ss3.yml"
        end

      end

    end

  end

end

This helped me too. It was working perfectly until I refactored my local asset precompile task out to a Capistrano recipes gem. Using top.upload fixed the issue.
