i solved my problem:
i just imported the new service that i created in the config file

The reason you're getting the error is because you do not have a DependencyInjection for your specific bundle. The program doesn't know where to look for your services.yml file.
You need an UaeUserExtension.php and Configuration.php inside your DependencyInjection folder under your User Bundle.
The easy solution to this is to generate the bundle via app/console generate:bundle. This way, it'll create your DependencyInjection for you automatically.
The manual solution would be to create a DependencyInjection folder inside your Uae/UserBundle. Inside DependencyInjection, create a file called Configuration.php and place the contents below:
<?php
namespace Uae\UserBundle\DependencyInjection;
use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;
class Configuration implements ConfigurationInterface
{
/**
* {#inheritDoc}
*/
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('uae_user');
return $treeBuilder;
}
}
And create a file called UaeUserExtension.php inside the same directory and place these contents inside:
<?php
namespace Uae\UserBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
class EnergyUserExtension extends Extension
{
/**
* {#inheritDoc}
*/
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
$loader->load('services.yml');
}
}
