Unable to compile packages because it's not under the rootDir

Type of Issue

[x] Bug Report
[ ] Feature Request

Description

I have a mono repo that contains an Angular app with a library within it generated by the angular CLI alongside the code for the API and a shared folder for models to be used across both the client and the API

The Library contains services that reference these shared models, however when I go to compile I get the following error;

error TS6059: File '/path/to/mono-repo/models/article/article.model.ts' is not under 'rootDir' '/path/to/mono-repo/angular/projects/core/src'. 'rootDir' is expected to contain all source files.

How To Reproduce

You can reproduce by simply trying to include a file from outside the rootDir that’s automatically generated by ng-packagr.

Here is the folder structure

- angular
-- projects
--- core
---- src
----- lib
------ article
------- article.service.ts
- models
-- article
--- article.model.ts

Expected Behaviour

For the library to compile or for a way to get around this stumbling block.

Version Information

ng-packagr: 3.0.3
@angular/compiler: 6.0.7
rollup: 0.59.4
tsickle: 0.29.0
typescript: 2.7.2

I have the same issue, But I am using a secondary entry point as stated in the secondary-entrypoints.md

The secondary entry point exports its own module which imports a file from the main entry endpoint, building the library throw this error:

BUILD ERROR error TS6059: File 'D:/Projects/ngx-scrollbar/projects/ngx-scrollbar/smooth-scroll/smooth-scroll.module.ts' is not under 'rootDir' 'D:\Projects\ngx-scrollbar\projects\ngx-scrollbar\src' . 'rootDir' is expected to contain all source files.

@alan-agius4 @JoostK How can I fix it?

@MurhafSousli that sounds fine, so you’d need two changes:

You added the following to the public api of ngx-scrollbar (the main entrypoint)

export * from '../smooth-scroll/src/public-api';

This is fine, as it is perfectly valid to re-export stuff from dependent entrypoints to become part of your own api surface, however the import specifier needs to become absolute:

export * from 'ngx-scrollbar/smooth-scroll';

This prevents the secondary entrypoint from becoming part of the compilation of the main entrypoint, avoiding the “not in rootDir” error.

---

Secondly, you added an import from NgScrollbarModule in the main entrypoint as follows:

import { SmoothScrollModule } from '../public-api';

This introduces a circular dependency issue, as the ../public-api file itself has an import into the ./lib/ng-scrollbar.module file, which introduces a cycle. In general, you should never import through the public api within the entrypoint itself, but instead import from the location where the dependency is declared. In your case for SmoothScrollModule, that would be ngx-scrollbar/smooth-scroll.
