Build path contains duplicate entry: 'src' for project 'org.osmdroid.google.sample.GoogleWrapperSample'

What steps will reproduce the problem?
1. start eclipse ( version 4.2 juno) on windows PC.
2. svn checkout http://osmdroid.googlecode.com/svn/trunk/ osmdroid-read-only
3. Import in eclipse (android - existing android code into workspace) and chose 
the local checked out directory of osmdroid-read-only as the root directory
4. STRANGE - I only see the following 2 projects 
org.osmdroid.google.sample.GoogleWrapperSample and
org.osmdroid.MapActivity
-> according to the HowToEclipse, i should see more projects - do you any ideas 
if this is a problem?
5. i tick the tickbox "copy into workspace" and get the following error message:
"Build path contains duplicate entry: 'src' for project 
'org.osmdroid.google.sample.GoogleWrapperSample'
Reason:
Build path contains duplicate entry: 'src' for project 
'org.osmdroid.google.sample.GoogleWrapperSample'"

there are the following entries in the error log:

Invalid property category path: ValidationPropertiesPage (bundle:

org.eclipse.wst.xml.ui.propertyPage.project.validation)

what can i do to get things runnable for android 2.3 (api 10)?

Thanks in advance for your help!

What is the expected output? What do you see instead?
-> i would expect there to be a number of importable projects (4 altogether?) 
when i import, rather than just 2. Also i would expect to be able to import 
without errors occuring. can you help please? what am i doing wrong?

What version of the product are you using? On what operating system?
-> i am using 3.08, i have a windows xp pc, i am using eclipse 4.2

Please provide any additional information below.

Thanks
