我从官方模板开始创建了一个新的Spray项目：
git clone git://github.com/spray/spray-template.git my-project
然后，从项目的根目录，我开始sbt：
cd my-project
sbt
问题是项目永远不会编译，我总是会遇到以下错误：

答案 0 :(得分：0)
将以下行添加到build.sbt
resolvers += "spray repo" at "http://repo.spray.io"
Revolver.settings
并在plugin.sbt中添加
addSbtPlugin("io.spray" % "sbt-revolver" % "0.7.2")
