For PSR-4 Auto Loader Users (composer.json):
Keep the migrations folder inside
classmap array and do not include it inside psr-4 object under
autoload head. As migrations' main class Migrator doesn't support namespacing. For example;
- First one clears all compiled autoload files.
- Second clears Laravel caches (optional)
- Third build the autoloader for namespaced classes.
- Fourth optimize various parts of your Laravel app and builds the autoloader for non-namespaced classes.
From this time onwards, you will not have to do this again and any new migrations will work correctly.
