使用MyEclipse8.5的自动加载组件功能，会把原本的J2EE插件给干掉，实在是可气，造成adt加上了，但J2EE不能用的尴尬状况。卸载之后使用手动添加adt插件的方法可避免该问题。
1、下载最新的adt插件ADT-10.0.1.zip
2、zip解压出plugins下的四个jar包：
com.android.ide.eclipse.adt_10.0.1.v201103111512-110841.jar
com.android.ide.eclipse.ddms_10.0.1.v201103111512-110841.jar
com.android.ide.eclipse.hierarchyviewer_10.0.1.v201103111512-110841.jar
com.android.ide.eclipse.traceview_10.0.1.v201103111512-110841.jar
3、复制到MyEclipse8.5的\Common\plugins目录下
4、修改MyEclipse 8.5\configuration\org.eclipse.equinox.simpleconfigurator目录下的bundles.info文件，添加以下内容：
com.android.ide.eclipse.adt,10.0.1.v201103111512-110841,file:/D:/Program Files/MyEclipse 8.5/Common/plugins/com.android.ide.eclipse.adt_10.0.1.v201103111512-110841.jar,4,false
com.android.ide.eclipse.ddms,10.0.1.v201103111512-110841,file:/D:/Program Files/MyEclipse 8.5/Common/plugins/com.android.ide.eclipse.ddms_10.0.1.v201103111512-110841.jar,4,false
com.android.ide.eclipse.hierarchyviewer,10.0.1.v201103111512-110841,file:/D:/Program Files/MyEclipse 8.5/Common/plugins/com.android.ide.eclipse.hierarchyviewer_10.0.1.v201103111512-110841.jar,4,false
com.android.ide.eclipse.traceview,10.0.1.v201103111512-110841,file:/D:/Program Files/MyEclipse 8.5/Common/plugins/com.android.ide.eclipse.traceview_10.0.1.v201103111512-110841.jar,4,false
5、重启MyEclipse
