Symfony2无法加载捆绑包

Question

我试图在新的Symfony2项目中使用我自己的捆绑包。 我已经创建了项目，并使用composer安装了所有必需的包。

这是我的项目的composer.json文件

{
"name": "symfony/framework-standard-edition",
"license": "MIT",
"type": "project",
"description": "The \"Symfony Standard Edition\" distribution",
"autoload": {
    "psr-4": { "": "src/", "SymfonyStandard\\": "app/SymfonyStandard/" }
},
"require": {
    "php": ">=5.3.9",
    "symfony/symfony": "2.7.*",
    "doctrine/orm": "^2.4.8",
    "doctrine/doctrine-bundle": "~1.4",
    "symfony/assetic-bundle": "~2.3",
    "symfony/swiftmailer-bundle": "~2.3",
    "symfony/monolog-bundle": "~2.4",
    "sensio/distribution-bundle": "~4.0",
    "sensio/framework-extra-bundle": "^3.0.2",
    "incenteev/composer-parameter-handler": "~2.0",
    "trancynn/devana-book-app": "dev-master"
},
"require-dev": {
    "sensio/generator-bundle": "~2.3"
},
"scripts": {
    "post-root-package-install": [
        "SymfonyStandard\\Composer::hookRootPackageInstall"
    ],
    "post-install-cmd": [
        "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::removeSymfonyStandardFiles",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget"
    ],
    "post-update-cmd": [
        "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::removeSymfonyStandardFiles",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget"
    ]
},
"config": {
    "bin-dir": "bin"
},
"extra": {
    "symfony-app-dir": "app",
    "symfony-web-dir": "web",
    "symfony-assets-install": "relative",
    "incenteev-parameters": {
        "file": "app/config/parameters.yml"
    },
    "branch-alias": {
        "dev-master": "2.7-dev"
    }
}
}

之后，我在AppKernel的registerBundles方法中加载所有必需的包，如下所示：

 new HWI\Bundle\OAuthBundle\HWIOAuthBundle(),
 new FOS\OAuthServerBundle\FOSOAuthServerBundle(),
 new FOS\RestBundle\FOSRestBundle(),
 new Voryx\RESTGeneratorBundle\VoryxRESTGeneratorBundle(),
 new Nelmio\CorsBundle\NelmioCorsBundle(),
 new JMS\SerializerBundle\JMSSerializerBundle(),
 new Nikola\DevanaBookAppBundle\NikolaDevanaBookAppBundle(),

但现在，运行服务器会导致致命错误：

Fatal error: Class 'Nikola\DevanaBookAppBundle\NikolaDevanaBookAppBundle' not found in C:\Users\Nikola\Desktop\symftest\mytest\app\AppKernel.php on line 25

我真的看不出有什么不对。 万一你需要它，这就是我的Bundle的composer.json
