我们知道可以使用诸如Tortoise SVN等工具执行svn操作,例如checkout、commit、update等。
现在我正在尝试使用Ant脚本执行svn操作,以便使svn过程更加简便。
我正在尝试使用svnkit SDK,其示例代码如下:

我可以得到一些历史输出:
revision: 7
author: username
date: Wed Apr 23 15:47:58 2014
log message: testing
changed paths:
A /testCode/src
当我调用 SVNCommitInfo 的 copyDir() 方法时,出现以下错误:
org.tmatesoft.svn.core.SVNException: svn: E160013: '/testCode/!svn/bc/2/C:/svnCommitCode/src' path not found: 404 Not Found (http://svnUrl)
我提供了源路径(本地系统目录路径)和目标路径(svn目录路径),我在这里做错了什么?(意思是在svn上存在相同的“src”文件夹,我只想用当前的本地目录替换它。)
有人能在这方面指导我吗?
