将android源码导入eclipse的问题

参照这个的做法： http://source.android.com/source/using-eclipse.html
在eclipse的problem窗口显示错误：
Project 'android7030' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/google-common_intermediates/javalib.jar'
Project 'android7030' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/gsf-client_intermediates/javalib.jar' 于是又参照：http://code.google.com/p/android/issues/detail?id=6102
修改.classpath删掉上面两个对应的：
<classpathentry kind="lib" path="out/target/common/obj/JAVA_LIBRARIES/gsf-client_intermediates/javalib.jar"/>
<classpathentry kind="lib" path="out/target/common/obj/JAVA_LIBRARIES/guava_intermediates/javalib.jar"/>结果problem窗口提示有70个错误，是类的名字无法解析等错误。
any ideas? 
thx.
