Using Windows 10.

I started new phoenix umbrella app using

mix phx.new myapp --umbrella

then created new ftp app in apps folder using

cd ./myapp/apps/
mix phx.new ftp --module FTP

But every time Im trying to call mix test I get

** (RuntimeError) could not lookup Ecto repo FTP.Repo because it was not started or it does not exist

Tried mix test from both umbrella root folder and from apps\ftp, results are all the same.

Tried to google around - found nothing reasonable.

Generated ftp app

mix test in Elixir umbrella app works as expected.

Does the FTP app need a repo? If not then there is a --no-ecto flag

mix phx.new ftp --no-ecto --module FTP

There will be other apps with ecto usage, so I need to resolve this issue anyway.

When extending an existing umbrella with a new Phoenix child app, you should use mix pix.new.web if there is no need for Ecto content. This includes when you’re relying upon an existing Ecto.Repo that’s already present in the umbrella. There’s also one for generating an Ecto child app, mix phx.new.ecto.

Oh, yeah, I missed a point of how phoenix project strucutre works.
So I need both ftp and ftp_web apps.

The first one, if it doesn’t use Ecto, can just be totally standard mix new ... [--sup] as appropriate.
