optimize-autoloader fails with Enums

[cxj]

My composer.json:

{
    "autoload": {
        "psr-4": {
            "App\\": "app/"
        }
    },
    "config": {
        "optimize-autoloader": true
    }
}

Output of composer diagnose:

When I run this command:

composer dumpautoload

I get the following output:

Generating optimized autoload files
Class App\Domain\Tasks\TaskStatus: located in ./app/Domain/Tasks/TaskStatus.php does not comply with psr-4 autoloading standard. Skipping.
Generated optimized autoload files containing 2 classes

And I expected this to happen:

I expected it to succeed, rather than fail on TaskStatus.php which is an Enum:

<?php
namespace App\Domain\Tasks;
Enum TaskStatus: string

If I remove (or set to false) the optimize-autoloader from the composer.json file, it works fine.

My guess: composer does not know how to optimize autoloading when Enums are present.

My guess from the excerpt of code you gave is this is caused by you using Enum instead of the expected enum keyword.

Should be an easy fix though, but you can use enum for now as workaround I believe.

Ah, right you are. I'm sorry I did not notice that.
