Answer 1

我看到你正在执行这一行：

cmd.exe /X /C "svn --non-interactive update D:\server

这意味着在 %PATH% 变量中设置的任何目录中都找不到 svn.bat 或 svn。

您的 Windows 系统上是否安装了 Subversion？如果您使用了 Subversion 的 CollabNet 版本，它应该会自动更新您的 PATH 以在 %PATH% 变量中包含C:\Program Files\Subversion\bin 或类似内容。如果没有，请打开系统控制面板，转到高级选项卡，然后单击设置环境变量。找到PATH环境变量，添加svn.exe程序所在的目录。

如果您尚未安装 Subversion，请从 CollabNet、SlikSVN 或 Wandisco 安装它。

Answer 2

您或许应该使用javasvn 提供程序。这样，您的构建/发布将不依赖于 SVN 客户端的本地安装和设置环境变量。
