"XX.ngfactory.js is missing from the TypeScript compilation" when ng build

I build my project use ng build --prod.

throw these error:

ERROR in ./node_modules/_@ng-bootstrap_ng-bootstrap@1.1.1@@ng-bootstrap/ng-bootstrap/alert/alert.ngfactory.js
Module build failed: Error: D:\Angular\video-server\node_modules\_@ng-bootstrap_ng-bootstrap@1.1.1@@ng-bootstrap\ng-bootstrap\alert\alert.ngfactory.js is missing from the TypeScript
 compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.
The missing file seems to be part of a third party library. TS files in published libraries are often a sign of a badly packaged library. Please open an issue in the library reposit
ory to alert its author and ask them to package the library using the Angular Package Format (https://goo.gl/jB3GVv).

Also there are popover.ngfactory.js, modal-window.ngfactory.js …

And my tsconfig.json:

@RajPack, I’ve tested, but doesn’t t work. As JHipster use Angular 6, the syntax is a little bit different that you said. The syntax should be instead (see https://github.com/angular/angular-cli/issues/10896 and https://github.com/angular/angular-cli/wiki/angular-workspace) :

"architect": {
  "build": {
    "builder": "@angular-devkit/build-angular:browser",
    "options": {
      "preserveSymlinks": true
    }
  }
}

As the problem is with command ./mvn verify (trigger packaging of the application), I’ve tried also with https://webpack.js.org/configuration/resolve/#resolve-symlinks, without more success. Have you an idea ?

It’s strange, because some of ngx-bootstrap modules are founded, like :

[INFO]  [67] ../node_modules-cache-angular-sample/node_modules/@ng-bootstrap/ng-bootstrap/datepicker/datepicker.module.js + 7 modules 39.1 KiB {1} [built]

But not :

Please, what do you think about that @pkozlowski-opensource ?

I’m getting this using cli 7.0.0.rc.0:

Can it be related? Should I open a new issue?
