How to Build a Spray Project Created from Official Template - scala

Question

I've created a new Spray project starting from official template:
git clone git://github.com/spray/spray-template.git my-project
Then, from the project's root, I started sbt:
cd my-project
sbt
The problem is that the project never compiles and I always get the following errors:
[info] Loading project definition from /home/j3d/Projects/my-project/project

Answer 1

add following lines to build.sbt
resolvers += "spray repo" at "http://repo.spray.io"
Revolver.settings
and in plugin.sbt add
addSbtPlugin("io.spray" % "sbt-revolver" % "0.7.2")
