Why does Project Facet window not open in eclipse?

Question

I have generated an app engine backend in eclipse for an existing Android app. I wanted to configure the project to use Cloud SQL by following this link https://developers.google.com/eclipse/docs/cloudsql-jpatools

When I do: right click on project -->Properties -->Project Facet --> selected JPA v2.0 and click Further configuration available option eclipse just gets stuck for ages and nothing happens?

What should I do? Also is there a way of using Endpoints with cloudsql without using JPA?

通过安装最新版本的Eclipse Juno v4.2，我能够解决此问题
