Type enum already exists

[msbsh]

I'm getting an Type enum already exists exception when trying to execute migrate:generate and don't fully understand, what I'm missing here. See (truncated) stacktrace below.

php artisan migrate:generate -vvv
Using connection: mysql

   Doctrine\DBAL\DBALException

  Type enum already exists.

Hello, thank you for report.

Unfortunately I can't reproduce your issue from my end.

The error is due to type enum is registered 2 times, while in the package enum should only register one time which is when command is triggered.

Do you mind to show me your composer.json to see if there is any conflict on this?

Probably 2 migration packages with same command php artisan migrate:generate or something

Sure thing and thanks for your support. I'm actually fairly new to composer/laravel/artisan in general, so I really much appreciate your support on this.

Thank you for sharing.

The generator has conflict with Larapack\DoctrineSupport\DoctrineSupportServiceProvider

protected function addDoctrineTypes(Connection $connection)
    {
        $name = $connection->getDriverName();

        foreach (Arr::get($this->types, $name, []) as $type => $handler) {
            if (!Type::hasType($type)) {
                Type::addType($type, $handler);
            }

            $connection->getDoctrineConnection()
                ->getDatabasePlatform()
                ->registerDoctrineTypeMapping($type, $type);
        }
    }

I should probably implement Type::hasType too to avoid conflict.

I will push a commit soon to fix this.
