如何在composer上使用Zend Framework 2的开发分支

在Apigility驱动的应用程序中，我的composer.json如下所示：

{
    "name": "misc - myproject-api",
    "description": "Skeleton Application for Apigility",
    "require": {
        "php": ">=5.3.23",
        "zendframework/zendframework": ">=2.3.2,<3.0.0",
        "zfcampus/zf-apigility": "~1.0",
        "zfcampus/zf-apigility-documentation": "~1.0",
        "zfcampus/zf-development-mode": "~2.0",
        "zfcampus/zf-rest": "~1.0-dev",
        "zf-commons/zfc-base": "dev-master",
        "zendframework/zend-developer-tools": "dev-master",
        "doctrine/doctrine-orm-module": "0.8.*"
    },
    "require-dev": {
        "zendframework/zftool": "dev-master",
        "zfcampus/zf-apigility-admin": "~1.0",
        "zfcampus/zf-apigility-welcome": "~1.0",
        "zfcampus/zf-deploy": "~1.0",
        "zfr/zfr-cors": "~1.0",
        "zend/zend-studio-development-mode": "~1.0"
    },
    "keywords": [
        "api",
        "apigility",
        "framework",
        "zf2"
    ],
    "support": {
        "email": "apigility-users@zend.com",
        "irc": "irc://irc.freenode.net/apigility",
        "source": "https://github.com/zfcampus/zf-apigility-skeleton",
        "issues": "https://github.com/zfcampus/zf-apigility-skeleton/issues"
    },
    "extra": {
        "branch-alias": {
            "dev-master": "1.0-dev",
            "dev-develop": "1.1-dev"
        }
    },
    "config": {
        "process-timeout": 5000
    },
    "type": "library",
    "license": "BSD-3-Clause",
    "homepage": "http://apigility.org/"
}

存在ZF2问题（导致以下错误：Fatal error: Cannot use object of type Zend'Db'ResultSet'ResultSet as array）。它已被修复，但尚未合并到master分支。

由于我现在需要它工作，我尝试切换到develop分支——更新了我的composer.json

{
    "name": "misc - myproject-api",
    "description": "Skeleton Application for Apigility",
    "require": {
        "php": ">=5.3.23",
        "zendframework/zendframework": "dev-develop as dev-master"
        ...
    }
    ...
}

并执行composer update:

$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Updating zendframework/zendframework (dev-master de98f63 => dev-develop be0b349)
    Checking out be0b3496b73a61a255d05e945b75f6fdf0995c31
Writing lock file
Generating autoload files

问题：我没有观察到任何更改，代码似乎仍然是从ZF2 master分支加载的（例如，我的本地Zend'Paginator'Adapter'DbSelect与master分支中相应类的状态完全相同）。

如何加载ZF2 develop分支

更新

我已经从Zend Framework的Packagist页面中检索了develop分支（2.4.*@dev）的composer require方向值。结果与dev-develop或dev-develop as dev-master相同——控制台显示下载的正确分支（或更好的是正确提交be0b349）

$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Removing zendframework/zendframework (2.3.4)
  - Installing zendframework/zendframework (dev-develop be0b349)
    Cloning be0b3496b73a61a255d05e945b75f6fdf0995c31
Writing lock file
Generating autoload files

但是更新后的代码仍然像master分支中的代码。

更新

$ cd [project root directory]/vendor/zendframework/zendframework
$ git status
# On branch develop
nothing to commit (working directory clean)

也就是说，分支是正确的。而且它也是最新的，自上次提交以来，git log显示的是2月3日的be0b3496b73a61a255d05e945b75f6fdf0995c31——这实际上是当前的HEAD版本。

所以，分支是正确的，修订是正确的。。。为什么代码是过期的？
