It seems flex and autol loading of vendor files sometimes breaks. Or i do not unrestand something.

I have installed clear skeleton, installed packages, it was working for some time, and that i got many errors kind of

Compile Error: require(): Failed opening required '/home/vagrant/Code/testsite/var/cache/dev/ContainerPRNapfp/srcDevDebugProjectContainer.php' (include_path='.:/usr/share/php')

(1/1) FatalErrorException

Compile Error: require_once(): Failed opening required '/home/vagrant/Code/testsite\vendor\symfony\framework-
bundle\Controller\ControllerNameParser.php' (include_path='.:/usr/share/php')

in srcDevDebugProjectContainer.php (line 93)
at srcDevDebugProjectContainer->__construct()
in srcDevDebugProjectContainer.php (line 13)

And so on, like, file is there, but autoloader can not see it. It starting after cache:clear command.

My composer.json
