Java 6 preventing deployment to appengine

Question

When I try and deploy my app to Google Appenginge, I get the following response:

Caused by: java.io.IOException: Error posting to URL: https://appengine.google.com/api/appversion/create?app_id=kittysplit&version=1& 400 Bad Request Java 6 applications are prevented from being deployed to Google App Engine from any version of the SDK, including older ones. If you need to continue to deploy Java 6 applications for compatibility reasons, you can request that your application be whitelisted for Java 6 deployment by visiting http://goo.gl/ycffXq.

I have set the project SDK to Java 1.7. My suspision is that a dependency in my POM.xml (included below) is causing this problem. Any ideas?

Answer 1

Why are you using an incredible old version of GAE? Have you tried upgrade the version to 1.9.6?

<dependency>
  <groupId>com.google.appengine</groupId>
  <artifactId>appengine-remote-api</artifactId>
  <version>**1.9.6**</version>
</dependency>
