Symfony Fails opening my sfDoctrineDatabase.class.php

My problem is very simple, yet I feel lost while looking at it ... I am currently working on a Symfony project located on an SVN repository.

It has worked well all day but suddenly it crashed...

Now I cant launch any page of my site. They all return me the same error message

Fatal error: sfAutoload::req开发者_运维技巧uire() [function.require]: Failed opening required '/Applications/MAMP/htdocs/prjAnnuaire/trunk/lib/vendor/symfony/lib/plugins/sfDoctrinePlugin/lib/database/sfDoctrineDatabase.class.php' (include_path='.:/usr/share/php:/usr/share/pear:/home/ar3s/ProjetAnnuaire/prjAnnuaire/trunk/plugins/sfPhpExcelPlugin/config/../lib/PHPExcel') in /home/ar3s/ProjetAnnuaire/prjAnnuaire/trunk/lib/vendor/symfony/lib/autoload/sfAutoload.class.php on line 165

If anyone has any idea, I am all ears ...

"symfony cc" fixed this for me.
