I am using google plugin for eclipse, I have only a jpa class and I
have been able to store some data yesterday. I have seen this data in
the 'datastore viewer'.

Google plugin should Enhance the class by itself and it is really what
it was doing 'till now.

NOW it seems it does not enhance anymore, by the way my app does not
work anymore, I can't see anything, server logs reports:
