Help about this error:Error during sbt execution: java.lang.NoClassDefFoundError: scala/ScalaObject_问答_开发者

Hi I tried to download lift 2.4 from http://liftweb.net/download .I'm following exactly the steps but I have the following error

Error during sbt execution: java.lang.NoClassDefFoundError: scala/ScalaObject

Do you know what's going wrong with the last line?Maybe something in my PATH?

My path is C:\Java\scala;%JAVA_HOME%\bin

JAVA_HOME C:\Java\jdk1.6.0_22

Where in 'scala' I have scala 2.8.0 final.

Try lift 2.4-M1 with Scala 2.9.0-1.

File in your project directory .../project/build.properties may contain next configuration

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

Run

sbt update

I've got working Scala 2.9.0-1, SBT 0.7.7, Lift 2.4-M1 (Maven helps a lot with dependencies)

My maven file pom.xml (maybe verbose but it works for me):
