Can't add umbrella project to deps of another umbrella project

I made an umbrella project json_media.
(GitHub - nallwhy/json-media: Personal media project)

And I’m going to create multiple elixir apps and want to include those apps to json-media app.

I succeeded to make another phoenix project my_app_web in json_media umbrella, and run it in json_media_web app.

  1. Add to deps
    {:my_app_web, in_umbrella: true}
  2. Add server: false option to config of MyAppWeb.Endpoint
  3. Add forwarding to MyAppWeb.Endpoint in router of json_media_web
    forward "/my_app", MyAppWeb.Endpoint

So I thought that I can make another ‘umbrella’ app my_app in private GitHub repo and include that in json_media_web.
(my_app umbrella includes my_app and my_app_web app)

But when I do that and run mix deps.get, it fails.

def deps() do
  [
    ...,
    {:my_app, git: "https://github.com/nallwhy/my_app.git"}
  ]
end

** (Mix) App my_app lists itself as a dependency

So, I renamed my_app to my_app_umbrella in deps/0. Then I succeeded to add my_app_umbrella to deps and run mix deps.get.

def deps() do
  [
    ...,
    {:my_app_umbrella, git: "https://github.com/nallwhy/my_app.git"}
  ]
end

But when I run mix phx.server, it fails.

** (Mix) Could not start application my_app_umbrella: could not find application file: my_app_umbrella.app

I think it can be succeeded if I can add only my_app_web to deps not whole my_app_umbrella.

Do you have any idea?

If it is possible, maybe livebook can be imported to another phoenix app.
