Problem

This bug happens only once. After installing the framework using the command php composer create-project --prefer-dist webfiori/app and running CLI of the framework, an error which says PHP Warning: mkdir(): File exists in C:\Server\apache2\htdocs\cli\test4\vendor\webfiori\framework\webfiori\framework\AutoLoader.php on line 619.

When running CLI again, the error disappears.
