12 directories, 17 files

This is a simple umbrella app

I had add import_config "../apps/*/config/config.exs" this code in “config/config.exs”

And my mix version is “1.5.2”

When I try to change the “apps/ks/config/config.exs” file, and run mix compile , it will not recompile the ks-app

I don’t know it’s a bug or something else

Any suggestion will be helpful

Thanks!
