and when I try to package it, compilation error occurs

I had the same problem with the Roo sample expenses.roo project. I solved it by adding the missing maven dependancy to project.

From Roo shell run this:

dependency add --groupId com.google.appengine --artifactId appengine-api-1.0-sdk --version 1.4.0

I don't know if my solutions is good, but I have just removed all folders from src folder with name gae and now I have built and deployed example gwt project without problems.

Another option is to specify the google app engine as the database while setting up the perrsistence.

persistence setup --provider DATANUCLEUS --database GOOGLE_APP_ENGINE

This can avoid the error of can't find google app engine related references.

This is fixed in Roo 1.1.4:
