Symfony4 bundle creation – impossible to generate a config file

  config, symfony

A code demo from this problem is visible on : GitHub and Packagist, please consult v0.0.3.

My problem : I want to generate a configpackagesowner_test.yaml file when I run :

composer require owner/test-bundle:0.0.3

But Composer display an error :

There is no extension able to load the configuration for "owner_test" (in "C:UsersUSERPROJECTvendorownertest-bundleDependencyInjection/../Resources/configowner_test.yaml"). Looked for namespace "owner_test", found "none".

Root key and bundle name is corrects and I have read all documentation finded, but nothing is right :

Thanks for help
