如何解决Spack 2.4.5和Scala 2.11使用哪个版本的Sbt和Sbt程序集？
当前，在AWS EMR群集中，我正在使用Scala v2.4.5随附的Spark v2.11。因此，在我的项目中，我想使用Scala v2.11以及相应的SBT和Sbt-Assembly版本。但是我发现一个或另一个版本与各种博客和Stackoverflow答案中的所有排列冲突。
这是我的依赖文件，它引发错误：

解决方法
似乎您正在混淆SBT使用的Scala版本和项目中使用的Scala版本。
如果您需要使用Scala 2.11构建项目，只需在build.sbt中指定
scalaVersion := "2.11.12"
您必须从scalaVersion := "2.11.12"文件夹中的plugins.sbt中删除project，因为SBT是使用特定的Scala版本预先构建的，因此无法更改。例如，0.13.17是用Scala 2.10构建的，而SBT 1.x.x是用Scala 2.12构建的。
您可以随意使用任何喜欢的SBT版本，但我建议使用最新的1.3.13和最新版本的相应插件。
