[Lift] Re: Impossible to use Mapper on GAE?
I have looked at SBT and I very much like what I see. Unfortunately, it doesn't solve the GAE/Lift problem. Google does not provide a URL from which the individual GAE jars can be downloaded; you have to download the App Engine SDK, unzip it, and copy the jars manually. Maven can do that, too, but it's ugly. One of the primarily reasons I started experimenting with GAE is that's it's such an elegant solution to the question of Where/how do I host my app?. Clever workarounds for the lack of Maven support for GAE can't help but to subtract from that elegance. The simplicity of the hosting solution is very quickly overwhelmed by the complexity of the set-up and build processes, at least when Lift and Maven are involved.

I cant think of a reason why mapper would not work on GAE? Mapper does not work with bigtable. You could write a record implementation if you really wanted to use bigtable.
