Eclipse安装插件时的一个蛋疼的错误：没法完成安装，由于找不到一个或多个必需的项。

"Cannot complete the install because one or more required items could not be found. Software currently installed: Shared profile 1.0.0.1316138460759 (SharedProfile_epp.package.java 1.0.0.1316138460759) Missing requirement: Shared profile 1.0.0.1316138460759 (SharedProfile_epp.package.java 1.0.0.1316138460759) requires 'org.maven.ide.eclipse [1.0.100.20110804-1717]' but it could not be found"

错误的提示大概就是这样，简直是无从下手找缘由啊。其实只须要以管理员身份运行Eclipse就ok了。
