eclipse中org.tigris.subversion.javahl.ClientException:RA layer request failed

用eclipse 同步SVN服务器突然无法访问了:
org.tigris.subversion.javahl.ClientException: RA layer request failed
svn: Server sent unexpected return value (403 Forbidden) in response to OPTIONS request for 'https://source.nexaweb.com/protected'
org.tigris.subversion.javahl.ClientException: RA layer request failed
svn: Server sent unexpected return value (403 Forbidden) in response to OPTIONS request for 'https://source.nexaweb.com/protected'
Can not map the project with svn provider
解决方法：
删除C:Documents and Settings\用户名\Application Data\Subversion\auth下的文件，删除svn登录信息。
win7目录在
C:\Users\fengbin\AppData\Roaming\Subversion\auth
删掉后,然后在eclise的svn库下新建svn地址,确定后,他提示重新输入svn的用户名和密码.
这个时候标志问题已经解决.
