工作名称空间和作曲家自动加载不正确

My project work is fine on Windows. When i try to run project on Ubuntu, i have error "Class ... not found" Im using silex, silex classes and other vendor classes is ok.It is find. But my classes not find. I used composer autoload. I fix my problem by composer comand "composer dumpautoload --optimize" but it is not ok?!

Why is that?

Make sure that the auto loaded files and folders have the correct (the same) casing as the namespaces and class snames. Windows file system don't care about the casing, *nix systems do...

On Windows:

some/folder == Some/Folder

While on *nix:

some/folder != Some/Folder
