尝试从netbeans部署我的google app engine应用程序时，出现以下错误：
com.google.appengine.tools.admin.HttpIoException: Error posting to URL: https://appengine.google.com/api/appversion/create?app_id=programworks&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.

这个错误到底是什么？我使用java 7作为我的库。
答案 0 :(得分：0)
创建一个新的小型Java 7项目，该项目可以成功部署和运行。将现有应用程序内容复制到新项目中。重命名旧项目以将其用作存档。重命名新项目以使用原始项目名称和应用程序ID。 （原this answer到this question）。
