Could not scan for classes inside / IlluminateQueueClosure.php
<p>Whenever I'm trying to <code>composer update</code> or delete vendor directory + <code>composer install</code> I am getting this error message:   </p>

<pre><code> [RuntimeException]
      Could not scan for classes inside "C:\Users\Mateusz\Documents\NetBeansProje
      cts\projectname\trunk\newproject\vendor/symfony/finder/Symfony/Component/Find
      er/src/Illuminate/Queue/IlluminateQueueClosure.php" which does not appear t
      o be a file nor a folder
</code></pre>

<p>Well, actually I dont have this file in my project at all. Inside of <code>/Finder</code> directory there is no <code>/src</code>. Could someone advice me on what to do now please?</p>

<p>I am pretty much beginning programmer so it honestly sounds to me like magic.
I work on a bigger project, they just told me to update my project and composer, but the composer update gives me this error.</p>
