解决方案

这是由于Forge缓存的Minecraft版本清单（manifest.json）文件格式错误。

找到以下两个文件夹：

• C:\Users\<当前用户>\.gradle\caches\forge_gradle\mcp_repo\versions\
• C:\Users\<当前用户>\.gradle\caches\forge_gradle\minecraft_repo\versions\

并删除这两个文件夹内以下五个文件：

• manifest.json
• manifest.json.etag
• manifest.json.md5
• manifest.json.sha1
• manifest.json.sha256

然后连接网络重新配置环境即可解决。
