Current behavior
I don't know if this is about angular compiler itself or additional warning from angular cli. I open issue here

I have an exorted interface in src/app/shared/form-utils/localized-input/localized-input.component.ts like:

export interface Language {
  id: number;
  cultureName?: "fr-CH" | "de-CH";
}

And I import this interface inside a component in src/app/shared/form-utils/autocomplete/autocomplete-plan-comptable-element/autocomplete-plan-comptable-element.component.ts I import it like this:
import {Language, LocalizationKey} from "../../localized-input/localized-input.component";
but when I compile (ng serve) I get warning like:

WARNING in ./src/app/shared/form-utils/autocomplete/autocomplete-plan-comptable-element/autocomplete-plan-comptable-element.component.ts
203:50-58 "export 'Language' was not found in '../../localized-input/localized-input.component'

Minimal reproduction of the problem with instructions

I keep having this issue as well, its really frustrating as I have to restart the serve every time I add a new interface.

Possible duplicate of #2034.

I'm also having this problem when working with interfaces. Every time I make a change to an interface and ng serve is running, the re-compile fails. Restarting ng serve fixes the issue. It seems as though ng serve caches the interfaces between automatic re-compiles.

Dupe of #2034.
