}

完成追溯 $this->manifestPath vendor/laravel/framework/src/Illuminate/Foundation/Application.php

protected function registerBaseBindings()

    static::setInstance($this);

    $this->instance('app', $this);

    $this->instance(Container::class, $this);

    ));
}

public function getCachedPackagesPath()

    return $this->bootstrapPath().'/cache/packages.php';
}

清除上图中的缓存文件php artisan clear-compiled

开始追溯 $this->build() vendor/laravel/framework/src/Illuminate/Foundation/PackageManifest.php

    public function build()
    {
        $packages = [];

        if ($this->files->exists($path = $this->vendorPath.'/composer/installed.json')) {

        $ignoreAll = in_array('*', $ignore = $this->packagesToIgnore());

        $this->write(collect($packages)->mapWithKeys(function ($package) {
            return [$this->format($package['name']) => $package['extra']['laravel'] ?? []];
        })->each(function ($configuration) use (&$ignore) {
            $ignore = array_merge($ignore, $configuration['dont-discover'] ?? []);
        })->reject(function ($configuration, $package) use ($ignore, $ignoreAll) {
            return $ignoreAll || in_array($package, $ignore);
        })->filter()->all());
    }

开始追溯 $this->packagesToIgnore() vendor/laravel/framework/src/Illuminate/Foundation/PackageManifest.php

    protected function packagesToIgnore()
    {
        if (! file_exists($this->basePath.'/composer.json')) {

        return json_decode(file_get_contents(
            $this->basePath.'/composer.json'
        ), true)['extra']['laravel']['dont-discover'] ?? [];
    }

发现composer.json中的 ['extra']['laravel']['dont-discover'] 可以阻止包自动发现
