Problem adding eclair sources to Eclipse 3.5

Question

I have sync eclair sources using repo ~/eclair_sources/

In Eclipse I create a project using existent sources and I add the former folder and I have a lot of errors like thos:

Description Resource    Path    Location    Type
android.R.attr cannot be resolved to a type SuggestionsAdapter.java /eclair/frameworks/base/core/java/android/app   line 411    Java Problem
_Original_Bitmap cannot be resolved to a type   Bitmap.java /eclair/frameworks/base/tools/layoutlib/bridge/src/android/graphics line 27 Java Problem

Any advise?
