Unable to locate stylesheet

[EmreAras04]

Command

build

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

16

Description

Hello,

I have an Angular project in version 16 that I've just migrated to version 17.
My problem is during the build, in fact I have 2 warnings coming from the Verona(Template file) : assets/layout files

▲ [WARNING] Unable to locate stylesheet: C:\assets\layout\layout\preloading.css
▲ [WARNING] Unable to locate stylesheet: C:\assets\layout\styles\theme\theme-light\indigo\theme.css

these errors appeared during migration to Angular 17...

I was able to remove the warnings by using the webpack builder proposed on Angular 16 which is @angular-devkit/build-angular:browser and not the one used (recommended) on Angular 17: @angular-devkit/build-angular:application or browser-esbuild.

I checked the Angular configuration files, but I couldn't find a solution.

Do you have any idea where this problem might be coming from?

Relative & Absolute path ?

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.
