致命错误：添加文件失败

解决方案 #

1. 处理文件名过长的致命错误 #

• 直接删除无关文件：从路径能看出，New Project – Google Cloud console_files是谷歌云控制台生成的缓存文件，和你的Spring Boot项目完全无关。直接删除整个文件夹，之后重新执行git add .即可。
• 开启Git长路径支持（可选）：如果确实需要保留长文件名的文件，在终端执行以下命令：

  git config --global core.longpaths true
  

  执行完成后重新尝试git add .

2. 处理换行符转换警告 #

• 配置自动换行符处理：在项目根目录创建.gitattributes文件，添加以下内容：

  * text=auto
  

  这样Git会根据操作系统自动处理换行符，避免出现转换警告。
• 关闭自动转换（不推荐）：如果不需要自动转换，执行以下命令：

  git config --global core.autocrlf false
  

  但此方法可能导致跨平台协作时出现换行符不一致的问题，谨慎使用。
