title: HttpResponseException: 500 Internal Server Error
body: <p>For weeks I've been using the Google App Engine plugin for eclipse to "Generate Cloud Endpoint Client Library" and it worked great. Today, it completely stopped working and responded with "An error occurred while attempting to generate the client libraries. See the error log for more details". The error log indicated a "HttpResponseException: 500 Internal Server Error".</p>
  
  <p>This is happening on code that I haven't touched for weeks and that worked yesterday, in Eclipse and Windows Environments that haven't had any updates whatsoever. </p>
  
  <p>I've tried on three computers-one of which was a completely new install of Eclipse and GAE Plugin For Eclipse. Then, I read through StackOverflow and it seems this problem creeps up occasionally on Google's side. So, is there another problem on Google's side? If so, please fix it soon.</p>
  
  <p>Also, is there any future plan to provide a local plugin that would allow developers to generate the code locally? Or, is there a site that shows the status of the component that seems to be broken on Google's side?</p>
  
  <p>Thanks</p>
