I've been playing around with Google Cloud Endpoints (Java) and I'm having trouble getting the APIs to update after I deploy to App Engine (using both Eclipse + Google Plugin and Android Studio).
I created an Endpoint based on a class called Process (annotated with JPA). It sits in my package (let's say: com.example). The first time I deployed it I had accidentally imported the wrong class (java.lang.Process instead of my com.example.Process). So I got this error when I tested one of the methods in the API explorer:
com.google.api.server.spi.SystemService invokeServiceMethod: cause={0}
javax.persistence.PersistenceException: No meta data for java.lang.Process. Perhaps you need to run the enhancer on this class?
I have then corrected the import, re-generated the client libraries and re-deployed the app to App Engine, but I keep getting the same error. As if App Engine still thinks I'm using java.lang.Process instead of my Process class.
I also made other changes. Like class member variable types and method names and re-deployed. But App Engine doesn't seem to notice these changes.
I read about how the API explorer "violently caches" so I tried clearing the cache, opened in another browser and even on another PC. Still nothing.
Also, I opened the discovery files for my api located in https://.appspot.com/_ah/api/discovery/v1/apis//v1/rest I noticed that the variables types I had changed are still listed as the old types.
I checked the logs for my deploys. They all look ok:

and in Admin Logs:

Anyone has any idea? Thanks in advance.
