`Class "Cake\Chronos\Chronos" not found` when doing composer update

[Can Vural]

Hi,

This started to happen recently. I'm not directly using chronos, but I have Laravel Nova in my dependencies that is using chronos.

Full stack trace from `composer update -vvv`

[ErrorException]                        
  Class "Cake\Chronos\Chronos" not found

This is happening at the Generating optimized autoload files stage of Composer.

I'm sorry I cannot give any reproducible case. But I'm hoping you have some ideas how to debug this further or how to fix it.

Without a way to reproduce we won't be able to help much sorry 😞

@markstory ok I just tried again to reproduce, and it was easy 😄

• composer create-project laravel/laravel:^8.0 chronosbug
• cd chronosbug
• composer require cakephp/chronos

This require command will throw the mentioned error.

Hope this helps.

Ah, now I just realized this only happens with the snapshot version of the Composer. Maybe I should open an issue there?
