java - 使用 Forge 启动 Minecraft 1.12.2 时出现错误 : Could not find or load main class net. minecraft.launchwrapper.Launch

Question

我用 Python 为 Minecraft 1.12.2 编写了一个启动器，它只是准备一个命令并使用子进程运行它。

这是在 Linux Ubuntu 上形成的命令:

#!/usr/bin/env bash

问题:
Ubuntu版本执行完美，没有任何提示，但是
Windows 版本说:

Error: Could not find or load main class net.minecraft.launchwrapper.Launch

它根本没有开始。

如您所见，Ubuntu 和 Windows 命令几乎相同。

我试图启动的 minecraft 安装(在 Ubuntu 和 Windows 上都使用)来自 Windows(由官方启动器生成，安装了 forge，我只替换标记为本地的库，因为它们依赖于平台)，它可以是开始在两个平台上使用官方启动器都没有任何问题，所以我认为我的世界文件丢失或损坏没有问题。此外，正如我在上面所写的，我能够使用我的自定义启动器启动它，但只能在 Ubuntu 上启动。

你们对我做错了什么有什么建议吗？

PS我尝试使用我的自定义启动器启动Vanilla Minecraft，问题完全相同，它适用于Ubuntu，但在Windows上失败并出现相同的错误(ofc它提到了vanilla class)

编辑我不提供 Python 代码，因为它很长，它只是将本地人提取到一个临时文件夹并形成启动 minecraft 的命令，该命令可以手动编写并粘贴到脚本中并执行。

Answer 1

好的，实际上，在 Windows 上，类路径分隔符是 ;不是 :
更换分隔符可解决此问题
