android ATD configeration

eclipse version: Eclipse Classic 3.7，在安装Android ADT 12.0.0时报如下错误：

Cannot complete the install because one or more required items could not be found.
Software currently installed: Android Development Tools 12.0.0.v201106281929-138431 (com.android.ide.eclipse.adt.feature.group 12.0.0.v201106281929-138431)
Missing requirement: Structured Text Model 1.1.203.v200802140626 (org.eclipse.wst.sse.core 1.1.203.v200802140626) requires 'bundle org.eclipse.wst.common.uriresolver [1.1.0,1.2.0)' but it could not be found
Cannot satisfy dependency:
From: Android Development Tools 12.0.0.v201106281929-138431 (com.android.ide.eclipse.adt.feature.group 12.0.0.v201106281929-138431)
To: org.eclipse.wst.sse.core 0.0.0

原因：是由所下载的eclipse插件不全导致的，缺少org.eclipse.wst.sse.core

解决方法：

1. 下载其他版本的eclipse，如Eclipse IDE for Java EE Developers， Eclipse for RCP and RAP Developers

2. 安装所缺少的插件，在eclipse的 help-->Install New Softwares-->Add 添加Location:http://download.eclipse.org/releases/indigo (注意eclipse的版本名，3.7叫indigo，3.6叫helios，3.5叫galileo，这个对所下插件的版本有影响，我刚开始就是因为用的galileo的链接，所以报了另一个版本依赖的错误)，然后找到一个叫WST Server Adapters的插件安装好，最后再安装Android ADT，到此，完美解决。
