I have an android APP which uses phonegap. 

/myprojects/MyAppv1/... (phonegap 2.6.0 repository)

I've upgraded to PhoneGap 3.3.0 and generated a new repository :

/myprojects/MyAppv2/...

Now, when I want to import the new project (File > New Project > Android Project From Existing Code), ADT tells me "Cannot import MyApp because the project name is in use".

How can I tell ADT to use the new repertory instead of the old one ? 

Thank you
