Error on Artisan commands when updating Composer dependencies

I am developing a library for Laravel which contains a service provider. I have added this library to another project's composer.json file.

The composer.json file for the "main project" contains the following scripts.

"scripts": {
    "post-root-package-install": [
        "php -r \"copy('.env.example', '.env');\""
    ],
    "post-create-project-cmd": [
        "php artisan key:generate"
    ],
    "post-install-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "pre-update-cmd": [
        "php artisan clear-compiled"
    ],
    "post-update-cmd": [
        "php artisan optimize"
    ]
},

I can include the library dependency just fine, except for one thing; the pre-update-cmd and post-update-cmd scripts throw an error and cause me a lot of headaches. When running sudo composer update to update the dependencies, I get the following error.

$ sudo composer update
> php artisan clear-compiled
PHP Fatal error:  Class 'MyName\MyProject\MyAwesomeServiceProvider' not found in /Users/Me/dev/MyProject/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146


  [Symfony\Component\Debug\Exception\FatalErrorException]                                              
  Class 'MyName\MyProject\MyAwesomeServiceProvider' not found  


Script php artisan clear-compiled handling the pre-update-cmd event returned with an error


  [RuntimeException]                                                                                         
  Error Output: PHP Fatal error:  Class 'MyName\MyProject\MyAwesomeServiceProvider'

I have Googled around quite a bit before asking this question and read through pretty much everything related that I could find. Apparently this is a known issue that has been discussed in multiple GitHub issues within the Laravel repository. However, I have yet to find a workaround, even after having tried multiple ones.

It appears that the issue is that the Artisan commands bootstrap Laravel, which leads to an error because the service provider is not available at this point - or something like that. Moving the clear-compiled command to post-update-cmd causes the same error, which surprises me a bit because I thought the service provider would be available at this point.

The only thing that works for me is to manually comment out the line that includes the service provider in config/app.php before running composer update and then adding it again afterwards. I have been doing this for a few hours, and it is already bothering the heck out of me, and I really cannot believe that this issue is around.

Does anyone know how to work around this error so that I don't get the error that my service provider is not found when updating the Composer dependencies for my project?
