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.

  • Yep, that works! You can download appengine-java-sdk-1.8.4 from here : https://code.google.com/p/googleappengine/downloads/detail?name=appengine-java-sdk-1.8.4.zip even it says the package is deprecated, just continue. – tugcem Nov 21 '13 at 15:36

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

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.

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.
