Angular AOT application will not build with AOT set to true in the angular.json file

Is this a regression?

This is new to the Angular work space so it is the first time I have tried it

Description

When creating an angular cli worskspace containing multiple libraries, cross library dependencies work in the non AOT compiled build but fail in the build when the AOT=true flag is set in the angular.json file. Error message is:
"Error in c:/Users/bruce.benton/Source/Repos/AotTest/dist/comp-container/comp-container.ngfactory.js
Module not found: Error: Can't resolve 'comp-container' in 'C:\Users\bruce.benton\Source\Repos\AotTest\projects\application1\src\ass'

This is not an upgrade issues and happens in a new work space created from scratch.

Anything else relevant?

Additional information since apparently I did not use the template correctly.

Minimal Reproduction:
Create a new Angular workspace => "AotTest"
Create a new library service => "service1"
Create a new library component container to contain re-usable components => "compContainer"
Create a new component inside the component container => "component1"
Create a new application library to consume both the service and the re-usable component
Implement a stub service endpoint in service1
Inject service stub into component1 and call service
load re-usable component component1 into application1 and add the selector to the html template
run ng serve application1 --open to demonstrate functionality
Create new configuration for application1 in angular.json called "devtest". Set the aot flag to true in this config
run ng build --configuration=devtest

You will get the error messages above.

This is not an upgrade and the project was created specifically for this test since I am having this problem in a real project. I would expect dependency resolution and scoping to work the same regardless of optimization.

Still learning the interface:-) Did not mean to close the issue

Hi @brucekbenton, the main issue here is that your libraries are named kebab cases example comp-container and not camelCase like compContainer.

The imports and path mappings in the tsconfig should be kebab-case.
https://github.com/brucekbenton/AotTest/blob/master/tsconfig.json#L27
https://github.com/brucekbenton/AotTest/blob/0ad15dc6ae865e41d889505b3700c1b53430fc32/projects/application1/src/app/app.component.ts#L3

This was a problem with older versions of the CLI. I suggest that you update to the latest version of the CLI and it's dependencies.

Since I am getting ready to do a large release at this time I don't really want to upgrade my entire environment. Therefore, I tracked down exactly what needed to get updated to resolve the dependency issues.

I had to make configuration changes for each entity generating the error message above (service or component). In this simple repro that means I needed to make these changes for comp-container.

I made the following changes:

• Updated all references in root workspace tsconfig.json file (AotTest/tsconfig.json) from "comp-container" to "CompContainer"
• Updated the "dest" value in the entity specific ng-package.json (AotTest/projects/comp-container/ng-package.json) to "CompContainer"
• Updated the "name" reference in the entity specific package.json file to "CompContainer"

I did not make any updates to angular.json or change any of the selector references or file names.

I also did this for my actual project which consisted of several services and components and it worked there as well. For my simple project I did not actually have to make the ng-package.json and package.json updates but I seemed to need it for my more complicated real project.
