Circular dependency in development setup caused by Gemfile.dev.rb

[skateman]

The current solution of loading a local classic UI repo in ManageIQ causes a circular dependency when running bundle update in the classic UI repo.

To fix this, it is necessary to wrap the line responsible for loading the UI in manageiq/Gemfile.dev.rb:

unless dependencies.detect { |d| d.name == "manageiq-ui-classic" }
  gem "manageiq-ui-classic", :path => "....."
end

@himdel could you please update the guides about it?
