Tailwind stylesheets are not generated for stylesheets other than app.css

[kniziol]

The problem

If you define more than one input_css path in the config/packages/symfonycasts_tailwind.yaml configuration file, Tailwind stylesheets are not generated for that CSS inputs:

# config/packages/symfonycasts_tailwind.yaml

symfonycasts_tailwind:
    input_css:
        - assets/app/styles/app.css
        - assets/orange-pizza/styles/orange-pizza.css
        - assets/brave-elephant/styles/brave-elephant.css

Please see an example in the following repository:
https://github.com/kniziol/TailwindBundle-and-AssetMapper

Steps to reproduce the issue

1. Clone https://github.com/kniziol/TailwindBundle-and-AssetMapper repo

2. Install DDEV. See more: Get Started

3. Run the following commands to start the project:

   ddev composer install

   ddev launch

4. Go to https://symfony-asset-mapper-paths-separation.ddev.site/brave/elephant

5. See the error:

   An exception has been thrown during the rendering of a template ("Built Tailwind CSS file does not exist: run "php bin/console tailwind:build" to generate it").
   

6. Run the command:

   ddev console tailwind:build

   See output similar to this one:

   Done in 90ms.

7. Refresh the page: https://symfony-asset-mapper-paths-separation.ddev.site/brave/elephant

8. Unfortunately, the error still exists 👇

More information

Stylesheet for the app entrypoint has been generated only:

ls -alh var/tailwind/
total 24
drwx------@ 4 kn  staff   128B Jan  5 19:00 .
drwx------@ 5 kn  staff   160B Jan  5 18:59 ..
-rw-------@ 1 kn  staff    10K Jan  5 19:00 app.built.css // <------- Here
drwx------@ 3 kn  staff    96B Jan  5 19:00 v3.4.17

I expected stylesheets generated for all CSS inputs defined in the configuration file:

# config/packages/symfonycasts_tailwind.yaml

symfonycasts_tailwind:
    input_css:
        - assets/app/styles/app.css
        - assets/orange-pizza/styles/orange-pizza.css
        - assets/brave-elephant/styles/brave-elephant.css

It looks like this is connected to #46

Workaround

Run the bin/console tailwind:build multiple times for each CSS stylesheet 👇

# For the assets/app/styles/app.css
ddev console tailwind:build

# For the assets/orange-pizza/styles/orange-pizza.css
ddev console tailwind:build assets/orange-pizza/styles/orange-pizza.css

# For the assets/brave-elephant/styles/brave-elephant.css
ddev console tailwind:build assets/brave-elephant/styles/brave-elephant.css

The same applies when we want to "watch" changes:

ddev console tailwind:build --watch
ddev console tailwind:build assets/orange-pizza/styles/orange-pizza.css --watch
ddev console tailwind:build assets/brave-elephant/styles/brave-elephant.css --watch

This behaviour is because of the reason explained here: #46 (comment)
