Question

Answer 1

尝试使用Scala 2.9.0-1升降机2.4-M1。

项目目录中的文件... / project / build.properties可能包含下一个配置

project.organization=Home
project.name=scala-lift
sbt.version=0.7.7
project.version=1.0
build.scala.versions=2.9.0-1
project.initialize=false

运行

sbt update

我已经开始使用Scala 2.9.0-1，SBT 0.7.7，Lift 2.4-M1（Maven对依赖项有很多帮助）

我的maven文件 pom.xml （也许详细，但对我有用）：
