I'm using greendao in a project and i like it but to be sure I checked the license another time. So I read here, that the generator is licensed under the GPL v3.
Does that mean, the generated classes are also licensed under GPL v3 and therefore cannot be used in a commercial (closed source) app?
You are fine to ship the generated classes with your app.
I just updated the FAQ to address this more clearly: http://greenrobot.org/greendao/documentation/faq/
