Description

I am having an error occur while trying to execute composer update. The issue appears to be from $this->symfonyDispatcher being of an incorrect type.

Steps To Reproduce

When executing composer update this error is thrown:

Symfony\Component\Console\Application::setDispatcher(): Argument #1 ($dispatcher) must be of type Symfony\Contracts\EventDispatcher\EventDispatcherInterface, Symfony\Component\EventDispatcher\EventDispatcher given, called in /home/shawn/cwUpgrade2/cw/vendor/laravel/framework/src/Illuminate/Foundation/Console/Kernel.php on line 486

Digging into this deeper I have found that $this->symfonyDispatcher within vendor/laravel/framework/src/Illuminate/Foundation/Console/Kernel.php is supposed to be of type Symfony\Contracts\EventDispatcher\EventDispatcherInterface but on line 141 is defined as Symfony\Component\EventDispatcher\EventDispatcher. When the function setDispatcher() is called on line 486 this causes an error as the function is expecting the type EventDispatcherInterface.

I have attempted to understand why on starting in Laravel 10.x the function getArtisan() was updated from:

protected function getArtisan()
{
    if (is_null($this->artisan)) {
        $this->artisan = (new Artisan($this->app, $this->events, $this->app->version()))
                                ->resolveCommands($this->commands)
                                ->setContainerCommandLoader();

        if ($this->symfonyDispatcher instanceof EventDispatcher) {
            $this->artisan->setDispatcher($this->symfonyDispatcher);
            $this->artisan->setSignalsToDispatchEvent();
        }
    }

    return $this->artisan;
}

while on Laravel 9.x it is this:

protected function getArtisan()
{
    if (is_null($this->artisan)) {
        $this->artisan = (new Artisan($this->app, $this->events, $this->app->version()))
                                ->resolveCommands($this->commands)
                                ->setContainerCommandLoader();
    }

    return $this->artisan;
}

A simple workaround would be to remove that added check as it seems unnecessary.
