SVN更新報the working copy needs to be upgraded解決辦法

SVN更新原始項目報：

The working copy needs to be upgraded
svn: The working copy at 'E:\work\ronhe\MyEclipse10\workspace_ftp0806\VBM_ALM_V7.0'
is too old (format 29) to work with client version '1.9.3 (r1718519)' (expects format 31). You need to upgrade the working copy first.

原因是新的環境的svn版本比原始檢出版本高。

解決辦法兩個：

1、重新檢出項目。

2、升級項目選中項目—>右鍵—>Team—>Upgrade；完成後重新更新即可。
