Difference between add_dependency and add_runtime_dependency?

Question

What is the difference between using add_dependency and add_runtime_dependency in a Rails engine's gemspec?

For example:

Gem::Specification.new do |s|
  s.add_dependency 'jquery-rails'
  s.add_runtime_dependency 'jquery-rails'
end

What's the difference between them?

They are the same. add_dependency is just an alias for add_runtime_dependency.

Are there any plans to deprecate `add_dependency`? – Jared Beck Jul 13 '15 at 03:50
