sbt执行期间出错：java.lang.NoClassDefFoundError:scala/ScalaObject

你知道最后一行出了什么问题吗？也许是我遇到了什么问题

我的路径是C:\J ava\scala；%JAVA\u HOME%\bin

JAVA\u HOME C:\JAVA\jdk1.6.0\u 22

---

在“scala”中，我有scala 2.8.0最终版本。

尝试使用scala 2.9.0-1提升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

跑

我有Scala 2.9.0-1，SBT 0.7.7，Lift 2.4-M1，Maven对依赖性有很大帮助

我的maven文件pom.xml可能很冗长，但它对我很有用：
