首先我得到一些警告。
[WARNING] Expected all dependencies to require Scala version: 2.10.6
[WARNING] com.twitter:chill_2.10:0.8.0 requires scala version: 2.10.5
[WARNING] Multiple versions of scala libraries detected!
然后是一些错误。
[ERROR] error: error while loading package, Missing dependency 'object java.lang.Object in compiler mirror', required by /home/joey/.m2/repository/org/scala-lang/scala-library/2.10.6/scala-library-2.10.6.jar(scala/package.class)
[ERROR] error: error while loading package, Missing dependency 'object java.lang.Object in compiler mirror', required by /home/joey/.m2/repository/org/scala-lang/scala-library/2.10.6/scala-library-2.10.6.jar(scala/runtime/package.class)

我想这一切都是相关的,但我不确定。我在pom.xml中没有看到这种依赖关系。我会把整件事都写进去以确保我没有遗漏任何东西。

我看不到任何地方硬编码的依赖版本,我看到的错误。
stackexchange不喜欢那些大部分都是代码的问题,但老实说,我不知道还能写些什么,因为我对mvn和scala还不熟悉。
