Eclipse on mac with google app engine plug in

Question

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.

Answer 1

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.

Answer 2

I had the same issue. Upgraded to the Java SDK 1.7 and the error message went away.

Answer 3

I had the same issue. Upgrading to JDK7 was not enough for me. I had to switch from Eclipse Kepler 32bits to a 64bits version. Now it works with GAE SDK 1.8.6.

Answer 4

The JDK7 requirement is actually mentioned in the appengine page here :

Warning: The App Engine SDK no longer supports Java 6. Applications that use Java 6 need to be migrated to Java 7. Existing applications that use the Java 6 runtime are still supported, but this support will be removed in a future release.
