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

Answer 1

In the end I have resolved my problem. The error was in a method in one of the endpoints that had as a parameter a com.google.appengine.api.datastore.Blob

To find the problem I executed manually (from a terminal) the creation of the cloud endpoint library, being able to see few more detailed line of output and so figuring out the endpoint that was having troubles. (To understand how to do so read the section "Generating a client library for android using endpoint.sh" there )
