Laravel migrations: Class "not found"

Question

I am deploying a Laravel barebone project to Microsoft Azure, but whenever I try to execute php artisan migrate I get the error:

[2015-06-13 14:34:05] production.ERROR: exception 'Symfony\Component\Debug\Exception\FatalErrorException' with message 'Class '' not found' in D:\home\site\vendor\laravel\framework\src\Illuminate\Database\Migrations\Migrator.php:328

Stack trace:

 #0 {main}   

What could be the problem? Thank you very much

Migration Class

<?php use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration;  class CreateUsersTable extends Migration {      /**      * Run the migrations.      *      * @return void      */     public function up()     {         Schema::create('users', function(Blueprint $table)         {             $table->bigIncrements('id');             $table->string('name', 50);             $table->string('surname', 50);             $table->bigInteger('telephone');             $table->string('email', 50)->unique();             $table->string('username', 50)->unique();             $table->string('password', 50);             $table->boolean('active')->default(FALSE);             $table->string('email_confirmation_code', 6);             $table->enum('notify', ['y', 'n'])->default('y');             $table->rememberToken();             $table->timestamps();                          $table->index('username');         });     }      /**      * Reverse the migrations.      *      * @return void      */     public function down()     {         Schema::drop('users');     } }

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;

"autoload": {     "classmap": [         "app/database/migrations"     ],     "psr-4": {         "Acme\\controllers\\": "app/controllers"     } } 

Then run:

php artisan clear-compiled  php artisan optimize:clear composer dump-autoload php artisan optimize 

• First one clears all compiled autoload files.
• Second clears Laravel caches (optional)
• Third builds the autoloader for namespaced classes.
• Fourth optimizes various parts of your Laravel app and builds the autoloader for non-namespaced classes.

From this time on wards, you will not have to do this again and any new migrations will work correctly.
