Integrating greenDao and Jackson

I am working on a project has an android side and a backend ,and for the JSON parsing am using Jackson library on both sides. using Play 2.0 for the backend ,Ebean is Jackson annotations friendly , but the problem is with GreenDao, since GreenDao uses code generation i have to type again all the annotations every time i migrate the database. I searched around and found only
this question but I can't find any template file

am using GreenDao 2.2.0

Thanks
