Symfony Command have an empty name in production environement

Question

I'm working on a Symfony2 Command, and I have an error when I try to run the command in prod environment, but it work perfectly in dev :

Everything is fine if I run :

php app/console mycommand:start

When I run

php app/console mycommand:start --env=prod

I get this error :

[LogicException]                                                                               
The command defined in "NameSpace\Of\MyClassCommand" cannot have an empty name.

Command definition :

services:
  my_service.command:
      class: NameSpace\Of\MyClassCommand
      arguments:
        name: mycommand:start
      tags:
        - { name: console.command }

Command :

class MyClassCommand extends Command
{

    /**
    * @param InputInterface $input
    * @param OutputInterface $output
    */
    protected function execute(InputInterface $input, OutputInterface $output)
    {
        // logic
    }

    ...
}

As you may notice, I don't overload the __construct or the configure methods. I tried but it didn't change anything. Same thing if I clean the cache.

Does anyone have an idea of what could be the difference between the prod and the dev environment, to cause this problem ?

Thank you

I finally found the solution, Ruslan you were right : clear the cache. But I had to manually nuke the cache folder, the cache:clear command was not enough.
