I'm new to Eclipse and App engine, following google getting started tutorial here i've installed eclipse kepler (4.3) and the according google app engine sdk (https://dl.google.com/eclipse/plugin/4.3)
when trying to create a new web application project i get the error: failed to initialized app engine
I've read relevant post and could not find something that worked for me.
I've the same problem but no way to solve. Via plugin or manually installed it returns same error: Failed to initialized App Engine SDK! Have you tried with Java SDK 1.7?
The solution is: You have to downgrade to appengine-java-sdk-1.8.4.
