rake routes draws outdated information

[a-b]

I'm trying to draw routes as soon as routes.rb changes. My Guardfile:

guard :rake, task: :routes, run_on_start: true, run_on_all: false do
  watch('config/routes.rb')
end

The problem is that when I change file rake routes output does not reflect recent changes. Also, it runs very fast, like the rails app been preloaded.

How to approach this problem?

The plugin will keep the rake process in cache, this might also be spring related.

I switched to guard-shell for my usecase, it should be trivial for yours, too.

https://github.com/guard/guard-shell

guard :shell do
  watch(%r{^config/routes.rb}) do
    `bin/rake routes`
  end
end
