While trying to add android source to eclipse, I am getting the following errors.
Project 'android' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/gsf-client_intermediates/javalib.jar'
Project 'android' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/google-common_intermediates/javalib.jar'
FYI, I have built the source successfully with full_maguro-userdebug configuration (for Galaxy Nexus) before adding this to eclipse. Since I couldn't find "create project from existing source" in Eclipse Indigo, I changed the location of the project to the root directory of the source. I refreshed the project several times with same error.
How to solve this issue?
You should go to Project -> Properties -> Java Build Path.
There open tab Libraries.
In this tab out/target/common/obj/JAVA_LIBRARIES/google-common_intermediates/javalib.jar should be changed to out/target/common/obj/JAVA_LIBRARIES/android-common_intermediates/javalib.jar by selecting javalib.jar from google-common_intermediates, pressing Edit and selecting instead android-common_intermediates.
Entry with gsf-client_intermediates javalib.jar can be simply deleted.

I would not recommend using eclipse for android source. Android is not a single project and it too big for an IDE like eclipse to handle.
Use simpler plain text editors like vim, emacs to browse the code
