How to use sbt with Google App Engine?

Question

Has anybody tried to setup sbt to work with Google App Engine? I dream about using development server auto-reloading after source changes.

Answer 1

Here's a template project using sbt + appengine which can be used to get started:

Also, instead of having to publish the sbt-appengine-plugin locally, you can use the following in Plugins.scala:

import sbt._
class Plugins(info: ProjectInfo) extends PluginDefinition(info) {
  lazy val appEngine = "net.stbbs.yasushi" % "sbt-appengine-plugin" % "2.1" 
    from "http://cloud.github.com/downloads/Yasushi/sbt-appengine-plugin/sbt-appengine-plugin-2.1.jar"  
}
