我看到你在执行这一行：

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？如果您使用的是CollabNet版本的Subversion，它应该会自动更新您的路径，以便在%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环境变量并添加

svn.exe

程序所在的目录

---

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

您可能应该使用

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环境变量的设置

svn命令在

PATH

环境变量中设置不正确。设置svn客户端/bin文件夹的路径。将svn添加到%PATH%env变量（如果已安装）或下载并安装svn。请参阅位于的官方二进制软件包列表或VisualSVN中的SVN命令行工具：；）洛莉也犯了同样的错误。我使用的是发布插件版本2.5.3，但没有选项来声明com.google.code.maven-scm-provider-svnjava依赖性。有什么建议吗
