java - Generating the API metadata for Cloud Endpoints classes failed

Question

I am working on a backend for my android app on google appengine from months up to now. Everything was working quite good until yesterday. I have not generated endpoint in last 2 months but when I tried to do so yesterday the error showed up.

That's the scenario.

1. From Android IDE (Eclipse 4.2) I click on 'Generate cloud endpoint client library'.
2. I have to wait a BIG amount of time...
3. The error appear (I will paste the stacktrace below).

Expected output -> all ok and my new endpoint library in my android project.
Actual output -> (stacktrace below).

I'm working on a machine with Ubuntu 13.04 64bit. And I have tried with 3 different versions of appengine sdk ( 1.9.2 ,1.9.3, 1.9.4 )

The problem reported is this one:

> com.google.appengine.repackaged.com.google.api.client.http.HttpResponseException: 400 Bad Request
{"error": {"message": "Bad Request", "code": 400, "errors": [{"message": "api exception", "debug_info": "Cannot decode JSON Schema for: {u'parameterName': u'resource'}"}]}}    *AppName*-AppEngine     Unknown Google App Engine Cloud Endpoints Problem Marker

And the stacktrace is this one:

I have tried many times to clean and build the project and to delete manually old *.api *.discovery files before a new build but nothing seems to work.

Can you please help me? Thank you
