Function calls are not supported in decorators while ng build --prod (AOT)

Type of Issue

[x ] Bug Report
[ ] Feature Request

Description

I’m using your package to build my library to be compiled to js. I’ve compiled everything without any problems, but when I’ll want to consume my library with ng build --prod (AOT enabled), I’m getting error: ERROR in Error during template compile of 'AppModule' Function calls are not supported in decorators but 'BsDropdownModule' was called. ng --prod --aot=false won’t produce any errors.

How To Reproduce

Create new project in Angular, create another module, in this module make forRoot method and post there some things, then pack whole package, and consume in second project. In second project import your module and use on it forRoot method.

Or simply: Download repo: https://github.com/Bloodcast69/aot-error , type npm install and ng build --prod.

Expected Behaviour

Want to build with AOT without errors (I need this to be compatible with Angular Universal)

I’ve fixed this. My problem was: I was importing some providers only from folder, not from file directly. For example: This was bad import { SampleService } from './services' This is good import { SampleService } from './services/sample.service'

Seeing this issue as well, but not for including packages I wrote. Issues are @ngrx/store, @ngrx/effects and TranslateModule. Which all required you to do .forFeature/forChild().

This also all appeared when I upgraded to “ng-packagr”: “2.4.2”, which I also upgraded to angular 6.0.0.rc-3. Few other apps I upgraded and didn’t have an issue so my guess is it’s something with ng-packagr.
