¿Cómo agregar repositorys de activos en la ruta correcta ?, no se encontró json válido en ninguna twig o label

Me gustaría que los repositorys de activos "assets.front" y "assets.admin" se instalen en la ruta "/ httpdocs / assets / vendor" como "Font-Awesome" y no en "/ vendor".

{ "autoload": { "psr-4": { "App\\": "src/app" } }, "repositories": [ { "type": "package", "package": { "name": "bower-asset/assets.front", "version": "master", "source": { "url": "git@github.com:User/assets.front.git", "type": "git", "reference": "master" } } }, { "type": "package", "package": { "name": "bower-asset/assets.admin", "version": "master", "source": { "url": "git@github.com:User/assets.admin.git", "type": "git", "reference": "master" } } } ], "config": { "vendor-dir": "vendor", "fxp-asset": { "installer-paths": { "npm-asset-library": "httpdocs/assets/vendor", "bower-asset-library": "httpdocs/assets/vendor" } } }, "require": { "fxp/composer-asset-plugin": "~1.3", "bower-asset/assets.front": "dev-master", "bower-asset/assets.admin": "dev-master", "bower-asset/Font-Awesome": "4.7.0" } } 

Intenté con "extra", sin éxito.

 "extra": { "asset-installer-paths": { "npm-asset-library": "httpdocs/assets/vendor", "bower-asset-library": "httpdocs/assets/vendor" }, "asset-repositories": [ { "type": "bower-git", "url": "git@github.com:User/assets.front.git", "name": "bower-asset/assets.front.git" }, { "type": "bower-git", "url": "git@github.com:User/assets.admin.git", "name": "bower-asset/assets.admin.git" } ] } 

Tengo este error:

 [Composer\Repository\InvalidRepositoryException] No valid bower.json was found in any branch or tag of git@github.com:User/assets.front.git, could not load a package from it. 

y mi bower.json existe en la raíz:

 { "name": "assets.admin", "description": "Assets admin", "homepage": "", "moduleType": "globals", "ignore": [ "/.*", "bower.json" ] } 

Tienes algunas ideas ?

Creé "config.json" en la carpeta "~ / .composer" con este código:

 { "config": { "prefernetworking-install": "dist", "github-protocols": ["https","http"], "github-oauth": { "github.com": "aa9a906cf406370b509bbce3a78829202b41b8e6" } } }
