弄了一天的subclipse也没装上，郁闷~~~~~~~~
无论采用本地安装还是站点安装都不行，在安装的时候显示错误：
Cannot complete the install because one or more required items could not be found.
Software being installed: Subclipse Integration for Mylyn 3.x (Optional) 3.0.0 (org.tigris.subversion.subclipse.mylyn.feature.group 3.0.0)
Missing requirement: Subclipse Integration for Mylyn 3.x (Optional) 3.0.0 (org.tigris.subversion.subclipse.mylyn.feature.group 3.0.0) requires
org.eclipse.mylyn.team.ui [3.0.0,4.0.0)' but it could not be found
里面有个含有Integration选项的勾掉就行了。
