禁止“模糊类解析”警告

Question

有没有办法在运行composer install 时禁用“模糊类解析”警告？

我使用的包在不同的文件夹中具有相同名称（和命名空间）的类。

我知道this bug，但这不是因为这些类实际上在供应商中出现了两次。我对此无能为力。

我也知道--no-autoloader 标志当然不会引发警告，只是因为它跳过了自动加载器的生成。

Answer 1

与其从vendor 目录中删除文件（应该避免），不如在composer.json 的exclude-from-classmap 部分中添加具有模糊类的文件/目录：

"autoload": {
    ...
    "exclude-from-classmap": [
        "vendor/somevendor/somepackage/directory/with/ambiguous/classes/",
        "vendor/somevendor/somepackage/src/AmbiguousClass.php"
    ]
},

然后 Composer 将在 classmap 生成期间忽略这些文件。

找到了一个解决方案，虽然不是那么明显。写了about it here。

当使用 paypal/merchant-sdk-php composer 包并运行 composer install 或 composer update 您会收到很多警告消息，如下所示：

Github 上已经有针对此问题的 bug 票证，但似乎没有以高优先级进行处理（因为它于 2014 年 7 月 31 日开放）。

找了一阵子，找到了问题的根源，就是/分别调用了PPAutoloader和PayPalAPIInterfaceService。 API 的每个类都被复制到 PayPalAPIInterfaceService 中。它用于示例（它是包的一部分），如果没有可用的 vendor/autoload.php 则使用 PPAutoloader 加载。但是这个内部逻辑（必须调用自动加载器）与“作曲家自动加载器生成过程”无关，它贯穿所有文件夹并构建它自己的配置。

那么解决办法是什么？

无法从自动加载器生成过程中排除文件夹（位于供应商文件夹中）。当然，您可以使用 --no-autoloader 标志运行 composer。但是你需要自己处理自动加载，这对于“仅”产生警告的问题来说有点激烈。

在这种情况下，有一种更简单的方法。由于该类仅与示例相关（系统中未使用），因此我可以简单地删除该文件。

为此，我使用 composer.json 的脚本部分和 pre-autoload-dump 命令事件（在自动加载器生成过程之前触发）。该命令删除包含 PayPalAPIInterfaceService 的服务文件夹。

"scripts": {
    "pre-autoload-dump": [
        "rm -rf vendor/paypal/merchant-sdk-php/lib/services"
    ]
},

删除 vendor 目录并运行 composer install 为我消除了错误。
