Doctrine Migrations: There are no commands defined in the "" namespace

Question

I'm trying to setup Doctrine Migrations as a standalone program and am having a little bit of trouble.

I have doctrine-migrations.phar and migrations.yml in the same folder.

migrations.yml contains the following:

name: Doctrine Sandbox Migrations
migrations_namespace: DoctrineMigrations
table_name: doctrine_migration_versions
migrations_directory: /home/myusername/myproject/Database/Update

Inside /home/myusername/myproject/Database/Update I have a file called Version20130608161001.php which contains the following:

namespace DoctrineMigrations;

use Doctrine\DBAL\Migrations\AbstractMigration;
use Doctrine\DBAL\Schema\Schema;

class Version20130608161001 extends AbstractMigration
{
    public function up(Schema $schema)
    {
        echo "Test";
    }

    public function down(Schema $schema)
    {

    }
}

When I run the command:

php doctrine-migrations.phar -v :migrate 

I get the following error message:

[InvalidArgumentException]
There are no commands defined in the "" namespace.

Exception trace:

You can modify your composer.json with this:

{
  "require": {
    "doctrine/doctrine-migrations-bundle": "dev-master"
  }
}

And then update: *Ensure you have the latest SF stable version in composer.json, in this moment 3.3.0

composer update

Finally, be sure to enable the bundle in AppKernel.php:

new Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle(),
