Desired functionality

Build app successfully

Mention any other details that might be useful

I found weird that the path logged in the error message mentions C drive twice ->"C:\C\code"
Project was originaly created in previous version of Angular and upgraded to ng6. Issue appeared after the migration to ng6

Workaround

I managed to compile my application if I change my file \src\app\index.ts from this

export { AppModule } from './app.module';

to this

export * from './app.module';

This seems like a bug but we'll need to look at a reproduction to find and fix the problem. Can you setup a minimal repro please?

You can read here why this is needed. A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.

This might be related to your directory structure so its really important to get an accurate repro to diagnose this.

I was hoping that the duplicated drive in path ("C:\C\code") would ring some bells.
I understand the need for repro-app, I'm going to try to setup a minimal repro-app and share asap.

You can clone this repo https://github.com/aguerot/angular-cli-issue-12035 for repro project

This is a barebone project generated w/ ng new repro-app where I added an index.ts file in app folder to export AppModule and updated main.ts to import from import { AppModule } from './app'; instead of import { AppModule } from './app/app.module';

see app/index.ts for offending code and workaround I found

I think this might be a problem with our barrel following logic.
