AppServiceProvider.php

<?php

    /**
     * Register any application services.
     *
     * @return void
     */

        //
        $this->app->register(GeneratorsServiceProvider::class);
        $this->app->register(MigrationsGeneratorServiceProvider::class);
    }
}

GeneratorsServiceProvider.php

<?php

            $config     = array_replace_recursive($config, $userConfig);
        }

        $this->app['config']->set('generators.config', $config);
    }
}

MigrateGenerateCommand.php

<?php

        if ($path = $this->option($option)) return $path;
        
        return config()->get("generators.config.{$configName}");
    }
}

MigrationsGeneratorServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Xethron\MigrationsGenerator\MigrationsGeneratorServiceProvider as BaseProvider;

class MigrationsGeneratorServiceProvider extends BaseProvider
{
    public function register()
	{
		$this->app->singleton('migration.generate',
            function($app) {
                return new MigrateGenerateCommand(
                    $app->make('Way\Generators\Generator'),
                    $app->make('Way\Generators\Filesystem\Filesystem'),
                    $app->make('Way\Generators\Compilers\TemplateCompiler'),
                    $app->make('migration.repository'),
                    $app->make('config')
                );
            });

		$this->commands('migration.generate');

		// Bind the Repository Interface to $app['migrations.repository']
		$this->app->bind('Illuminate\Database\Migrations\MigrationRepositoryInterface', function($app) {
			return $app['migration.repository'];
		});
	}
}

Fix for Xethron/migrations-generator#166

Is the file MigrateGenerateCommand.php should be placed in app\Providers folder too?
