Why do I have to run composer dump-autoload command to make migrations work in laravel

Question

I have built some migration classes in my application to create the tables I need, but I keep getting errors. I need to run this command:

composer dump-autoload

Only then it works again as expected. Am I doing something wrong that generates this error or this is a normal behaviour with migrations?

Below is the error that I get when running the migration process:

  [Symfony\Component\Debug\Exception\FatalErrorException]  
  Class 'CreateVideoStatusTable' not found

You should run   composer dump-autoload   and if does not work you should   re-install composer

OK so I think i know the issue you re having   Basically  because Composer can t see the migration files you are creating  you are having to run the dump-autoload command which won t download anything new  but looks for all of the classes it needs to include again  It just regenerates the list of all classes that need to be included in the project  autoload classmap php   and this is why your migration is working after you run that command   How to fix it  possibly  You need to add some extra information to your composer json file    autoload          classmap              PATH TO YOUR MIGRATIONS FOLDER             You need to add the path to your migrations folder to the classmap array  Then run the following three commands     php artisan clear-compiled  composer dump-autoload php artisan optimize   This will clear the current compiled files  update the classes it needs and then write them back out so you don t have to do it again   Ideally  you execute composer dump-autoload -o   for a faster load of your webpages  The only reason it is not default  is because it takes a bit longer to generate  but is only slightly noticable    Hope you can manage to get this sorted  as its very annoying indeed

Short answer  classmaps are static while PSR autoloading is dynamic   If you don t want to use classmaps  use PSR autoloading instead
