错误的symfony配置

I have a problem with configuration of my project and I can't see where is the mistake...

AppKernel.php ...

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            ...
            new CMS\CoreBundle\CMSCoreBundle(),
        ];

app/config/routing.yml

cms_core:
    resource: "@CMSCoreBundle/Resources/config/routing.yml"
    prefix:   /

src/CMS/CoreBundle/Resourcers/config/routing.yml

cms_core_homepage:
    path:     /
    defaults: { _controller: CMSCoreBundle:Default:index }

src/CMS/CoreBundle/Resources/views/index.html.twig

{% extends "@CMSCoreBundle/template.html.twig" %}

{% block content %}
test
{% endblock %}

src/CMS/CoreBundle/Resources/views/template.html.twig

{% block content %}
Template block
{% endblock %}

And I'm getting this message

There are no registered paths for namespace "CMSCoreBundle" in CMSCoreBundle::index.html.twig at line 1.

Where is the mistake please ? Thank you guys.

I think you have 2 ways to fix it.

you can add your bundle to the path

#app/config/config.yml
twig:
    paths:
        "%kernel.root_dir%/../src/CMS/CoreBundle/Resources/views/": CMSCoreBundle

Or try to extend your template like that

{% extends "CMSCoreBundle:template.html.twig" %}

I'm not 100% sure for the 2nd solution.

Hope it may helps you
