不得不說svn給我們的團隊開發帶來了N多便利，也帶來了不少麻煩；特麼是初學者！這個過程中我是急的想撓牆，經歷風與雪的洗禮，蒐集一些資料總結出現如下：

在安裝svn外掛時若出現如下問題：

一、報錯

Cannot complete the install because one or more required items could not be found.
  Software being installed: Subversion Revision Graph 1.0.7 (org.tigris.subversion.subclipse.graph.feature.feature.group 1.0.7)
  Missing requirement: Subversion Revision Graph 1.0.7 (org.tigris.subversion.subclipse.graph.feature.feature.group 1.0.7)
 requires 'org.eclipse.draw2d 3.2.0' but it could not be found

解決方法：更新GEF,更新地址:http://download.eclipse.org/tools/gef/updates/releases/

二、報錯

1. Cannot complete the install because one or more required items could not be found.  
2.   Software being installed: Subversion Revision Graph 1.1.1 (org.tigris.subversion.subclipse.graph.feature.feature.group 
   1.1.1)  
3.   Missing requirement: Subversion Revision Graph 1.1.1 (org.tigris.subversion.subclipse.graph 1.1.1) requires 'bundle org.eclipse.draw2d 3.2.0' but it could not be found

如果還是不行的話，那就換掉adt 吧
