网上搜索了一下，参考的是这个地址，因为我下载的是2012-7-4月的发布的一个hudson版本》
，而该版本对应的subversion插件的版本为2.3.0版本，找到对应的hudson的插件的仓库地址： ，发现下面没能找到最新的subversion版本，最新的版本也是2.3.0版本的。
后来在这个地址：，
上面的哥们也给出了一个他们对于这个bug的刚刚解决的方案，就是一个最新的svn的补丁包，下载地址是：
，可以他最后也说了，截止到7月5日还是没有看到该项目发布者发布到网上最新的2.3.2的版本。
所以下载就成了问题了，还没有发布？
解决方法:
后来在manger plugin中进入advanced的tab页面中看到了这个设置方案，可以在这里进行手工更新插件，只需要下载一个hpi文件即可。
呵呵@解决了！
可是插件可能下载不了，参考一个地址可以下载最新的插件：
解决方案：一个哥们说是删除对应的一个目录就可以了，参考文档：
