I have a library with a workspace containing two projects, one for the library itself and one for a test application.
├── projects
├── midi-app
└── midi-lib
In the workspace tsconfig.json file I configured the baseUrl property:
"baseUrl": "./projects/midi-lib/src"
For the record, in this same file there are also some paths mappings:
"paths": {
"midi-lib": [
"dist/midi-lib"
],
"midi-lib/*": [
"dist/midi-lib/*"
],
"@angular/*": [
"./node_modules/@angular/*"
]
}
There is also a projects/midi-lib/tsconfig.lib.json file which extends on the above tsconfig.json file:
"extends": "../../tsconfig.json",
but it contains no such baseUrl nor paths properties.
The build command of the library sub project is successful:
$ ng build midi-lib --watch

I have a projects/midi-lib/src/lib/service/index.ts file which contains:
export { MidiService } from 'lib/service/midi.service';
export { KeyboardService } from 'lib/service/keyboard.service';
export { SynthService } from 'lib/service/synth.service';
export { CommonService } from 'lib/service/common.service';
export { GeneratorService } from 'lib/service/generator.service';
export { MelodyService } from 'lib/service/melody.service';
export { ParseService } from 'lib/service/parse.service';
export { SheetService } from 'lib/service/sheet.service';
and allows such import statement:
import { SynthService } from 'lib/service';
I also have a projects/midi-lib/src/lib/index.ts file which contains:
export { Device } from 'lib/model';
export { MidiService } from 'lib/service';
export { DeviceStore, SoundtrackStore } from 'lib/store';
but is not being used yet, or so it seems to me.
I'm trying to use this library with the test application but its build command ng serve fails with the error:
$ ng serve

ERROR in ../midi-lib/src/lib/model/index.ts
Module build failed (from /home/stephane/dev/js/projects/angular/midi-lib/node_modules/@ngtools/webpack/src/index.js):
Error: /home/stephane/dev/js/projects/angular/midi-lib/projects/midi-lib/src/lib/model/index.ts is missing from the TypeScript compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.
Before trying to simply use the baseUrl property for absolute import statements, I tried using the paths property, but I failed miserably.
As a side note, my VSCode doesn't show any error.
I'm under version:
Angular CLI: 7.3.9
