Is NetBeans not accepting _ide_helper from Laravel?

Using NetBeans 8.2 with Laravel, I'm setting the _ide_helper.php to my project as described in his link https://github.com/barryvdh/laravel-ide-helper, it was set on terminal the command

composer require barryvdh/laravel-ide-helper

then after, it was added into config/app.php the line

Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class,

and for last, the command on the project folder

php artisan ide-helper:generate

but nothing has changed apparently. No auto complete, no references. Here are some images comparing what is expected and what is happening.

Expected

Happening

Plus, NetBeans is marking an error inside the ide_helper file which confuses the syntax by the name of the function ('if'). I'll put an image of the part showing the error

Error_NetBeans_ide_helper

I've rebooted NetBeans, tried downloading and setting directly the file, but no lucky. Is the function 'if' causing the problem? Or is NetBeans not accepting the _ide_helper?
