説明

### Which @angular/* package(s) are the source of the bug?

Don't known / other

### Is this a regression?

Yes

### Description

We have a set of auto-generated files that contain locale information for countries that's based off of CLDR information.

**Example File**
```
Filename: src/app/auto-generated/countries/XX.ts` where XX is the locale id (e.g. `en-us`).
export const data: [string, string][] = [['US', 'United States'], ['CA', 'Canada'], ...];
```

We used a Resolver class to retrieve this information.

```
export class CountryResolver implements Resolver {
constructor(@Inject(LOCALE_ID) private readonly localeId: string) {}

resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Promise {
return this.getCountries(this.localeId);
}

getCountries(localeId: string): Promise {
const locale = toLower(localeId);
// Attempt to import locales, otherwise import default locale 'en'
return import(`../../../auto-generated/countries/${locale}`)
.then(({ data } => resolve(data))
.catch(() => import(`../../../auto-generated/countries/en`))
.then(({ data } => resolve(data)));
}
```

This has worked, even in Angular 15.

I have just upgraded to Angular 17, this no longer works. I now get the following error:

```
[ERROR] File 'src/app/auto-generated/countries/en.d.ts' is missing from the TypeScript compilation. [plugin angular-compiler]
src/app/pages/input/input.resolve.ts:4:16:
4 │ ...urn import(`../../auto-generated/countries/${locale}...
╵ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Ensure the file is part of the TypeScript program via the 'files' or 'include' property.
```

It outputs that error for every file name in that directory.

I have tried adding the following to `tsconfig.app.json` as well as `tsconfig.json` but it doesn't do anything:

```
include: ['src/app/auto-generated/**/*.ts']
```

### Please provide a link to a minimal reproduction of the bug

### Please provide the exception or error you saw

```true
[ERROR] File 'src/app/auto-generated/countries/zh-hant.d.ts' is missing from the TypeScript compilation. [plugin angular-compiler]

### Please provide the environment you discovered this bug in (run `ng version`)

```true
Angular CLI: 17.0.2
Node: 18.16.0
Package Manager: npm 9.5.1
OS: linux x64

Angular: 17.0.4
... animations, common, compiler, compiler-cli, core, forms

Package Version

@angular-devkit/architect 0.1700.2
@angular-devkit/build-angular 17.0.2
@angular-devkit/core 17.0.2
@angular-devkit/schematics 17.0.2

@schematics/angular 17.0.2
ng-packagr 17.0.2
rxjs 7.8.1
typescript 5.2.2
zone.js 0.14.2
```

### Anything else?

I have also tried just converting the files to JSON, placing them in the `assets` folder and importing those via

```
import(`../../assets/path/to/${localeId}.json?raw`)
```

Btut I always get a console error saying that `../../assets/path/to/file/en.json` doesn't exist.

I ended up just using `fetch` with the files in the `assets` folder, however, it looks like this might not work with SSR.

調査の方向性

まず、Angular CLI 17 を使用して、リンクされた StackBlitz プロジェクトで拡張子なしの動的 import の失敗を再現し、次に application builder と tsconfig.app.json がそれらの import をどのように処理するかを調査します。生成された国別ファイルについて報告された angular-compiler エラーを追跡します。再現ケースが正常にビルドされるか、サポートされる制限が coverage 付きで明確に確立された時点で作業は完了です。
