title: Composer update error while trying to install ccdn-forum-bundle Symfony2
body: <p>first of all I would like to say that I'm relatively new to symfony and I work with Netbeans.</p>
  
  <p>My first problem occurs when I'm trying to install ccdn-forum-bundle like it's said here: </p>
  
  <p><a href="https://github.com/codeconsortium/CCDNForumForumBundle/blob/master/Resources/doc/install.md" rel="nofollow">https://github.com/codeconsortium/CCDNForumForumBundle/blob/master/Resources/doc/install.md</a></p>
  
  <p>When I try to update-dev with composer I get this error:</p>
  
  <p>[RuntimeException]<br>
    Failed to execute git status --porcelain --untracked-files=no<br>
    "git" is not recognized as an internal or external command, operable program or batch file.</p>
  
  <p>It occurs when composer is trying to update friendsofsymfony/user-bundle and when I try to run my project I get this error from symfony:</p>
  
  <p>ClassNotFoundException: Attempted to load class "MonologBundle" from namespace "Symfony\Bundle\MonologBundle" in C:\xampp\htdocs\PortalInternoHUPR\app\AppKernel.php line 14. Do you need to "use" it from another namespace?</p>
  
  <p>I tryed to fix it by running install dev in composer, but then I get this other one:</p>
  
  <p>Fatal error: Class 'Knp\Bundle\PaginatorBundle\KnpPaginatorBundle' not found in C:\xampp\htdocs\MyProject\app\AppKernel.php on line 23
  Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-install-cmd event terminated with an exception</p>
  
  <p>[RuntimeException]<br>
    An error occurred when executing the ""cache:clear --no-warmup"" command. </p>
  
  <p>Thanks.</p>
