Question

I’m updated the ADT plugin to the last version (20) and the android-sdk tool. Now when I try to import an existent Android Maven to Eclipse raise the exception An internal error occurred during: "Importing Maven projects".
com/android/io/StreamException, and creates the eclipse project but not like Android project as before. The previous existent (maven android) projects in the workspace works fine.

The Eclipse full exception trace when import the project is the following:

!ENTRY org.eclipse.osgi 2 1 2012-06-29 19:02:34.421
!MESSAGE NLS unused message: LifecycleMappingPropertyPage_this_message in: org.eclipse.m2e.core.ui.internal.messages

Can anybody solves it? Is needed an update of the m2e Android connector?

This is a known issue with the m2e-android plug-in caused due to changes in the ADT API:

Please be patient while we find a fix.
