VS2022远程调试Ubuntu CMake项目遇Rsync指定方法不支持错误

我正在开发基于CMake的项目，使用VS2022社区版的Connection Manager通过SSH连接Ubuntu虚拟机，连接已成功，但构建项目时出现**Rsync error. Specified method is not supported.**错误。已更新本地rsync版本，但问题仍未解决，错误日志如下：

1> Extracted CMake variables.

修复方案与排查方向 #

• 检查Ubuntu端rsync版本与配置
  • 确保Ubuntu虚拟机上安装了rsync，版本不低于3.1.0，执行rsync --version查看当前版本
  • 无需额外启动rsync daemon，VS通过SSH直接调用rsync，确认远程用户可正常执行rsync命令
• 调整VS2022文件同步设置
  • 打开工具->选项->跨平台->连接管理器，选中目标Ubuntu连接，点击修改
  • 在高级选项卡中，将文件同步方式设置为Rsync (SSH)，避免选择SCP等不兼容模式
  • 若配置了自定义rsync参数，暂时清空参数后测试，排除参数不兼容问题
• 验证SSH连接权限与环境
  • 确认SSH用户对远程项目目录有读写权限，执行ls -ld /home/你的项目路径检查权限设置
  • 执行ssh 用户名@ubuntu服务器地址 which rsync，确认rsync在远程用户的PATH环境变量中
• 重置VS项目缓存与配置
  • 删除本地项目的.vs目录和CMake构建缓存文件夹（如out/build）
  • 重新触发CMake配置：点击CMake->删除缓存并重新配置
• 更新VS2022跨平台组件
  • 打开VS Installer，检查**Linux开发用的C++**组件是否为最新版本，更新组件以修复工具链兼容性问题
