Java 为什么在尝试启动MC下载文件失败时出现此错误。minecraftforge-9.11.1.1345.jar？

我目前作为一名开发者为Crafting Dead工作，我需要为我们的mod制作一个安装程序。安装程序必须从我们的下载服务器下载最新的cd mod，将.jar放在mod文件夹中，然后安装forge 1.6.4+并将其添加到launcher_profiles.json中。我已经用java制作了安装程序，它可以正常工作。当我尝试在windows上用forge 1.6.4启动mc时，它可以工作，但在mac上不工作。 我得到这个错误：

Failed to download file. minecraftforge-9.11.1.1345.jar
Name: minecraftforge-9.11.1.1345.jar
URL: http://files.minecraftforge.net/maven/net/minecraftforge/minecraftforge/9.11.1.1345/minecraftforge-9.11.1.1345.jar

我必须给这个版本一个自定义名称。我称之为：CraftingDead，以便用户知道这是我们国防部的forge版本

您的错误

错误详细信息：HTTP 404:Not Found

表示您正在请求服务器上不存在的资源。这可能意味着URL错误，如果文件已被移动，或者服务器上不再存在该文件，也可能发生这种情况

在您提出此问题的前一天，也有关于minecraftforge服务器出现问题的报告，这些问题可能在您提出请求之前无法解决。

---

您可能还想将URL更改为使用https而不是http，因为据我所知，计划将服务器切换为https，这样您的请求将再次失败。

如果您指的是MC forge，您可能应该使用[minecraft forge]标记而不是[forge]标记
