laravel/lumen-framework:“5.7.*” and flipbox/lumen-generator:“^5.6” Class Not Found

问题

I think this is related to composer autoload not detecting packages outside laravel/lumen-framework/src

Is my above assumption to the below problem correct? Shall I include psr-4 key inside "autoload-dev" nested object?

I really appreciate your help.

Thanks.

Below is Error Exception, composer.json snippet and Stack Trace Logs

Below composer.json

        {
        ...
        "autoload": {
            "classmap": [
                "database/seeds",
                "database/factories"
            ],
            "psr-4": {
                "App\\": "app/"
            }
        },
        "autoload-dev": {
            "classmap": [
                "tests/"
            ]
        },
        ...
    }

Below is the stack trace log found under storage/lumen.log

回答1:

It was really a stupid mistake, after debugging and going to the north pole back and forth. I figured out that I had the class namespace referenced wrongly so instead of using below:

if ($app->environment() !== 'production') {
    $app->register(FlipBox\LumenGenerator\LumenGeneratorServiceProvider::class);
}

I should have used small letter b instead of B so the below works:

if ($app->environment() !== 'production') {
    $app->register(Flipbox\LumenGenerator\LumenGeneratorServiceProvider::class);
}

Then doing php artisan list you will get all the make:* goodies:

What really worked for me, was to run composer install, that installed dependencies that I had not yet installed (due to changes made by others by the use of GIT repository).
