我试图用spark和sparklingwater创建一个简单的scala应用程序 build.sbt 文件：

name := "test"

version := "0.1"

scalaVersion := "2.11.12"

logLevel := Level.Error

lazy val versions = new {
  val spark = "2.4.5"
  val sparklingWater = "3.30.0.5-1-2.4"
  val play = "2.7.5"
  val scala = "2.11.12"
}

compileOrder in Compile := CompileOrder.JavaThenScala

libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-core_2.11" % versions.spark,
  "org.apache.spark" % "spark-mllib_2.11" % versions.spark,
  "org.apache.spark" % "spark-sql_2.11" % versions.spark,
  "org.apache.spark" % "spark-repl_2.11" % versions.spark,
  "ai.h2o" % "sparkling-water-package_2.11" % versions.sparklingWater,
  "org.scala-lang" % "scala-compiler" % versions.scala,
  "org.scala-lang" % "scala-library" % versions.scala,
  "org.scala-lang" % "scala-reflect" % versions.scala,
)

assemblyMergeStrategy in assembly := {
  case PathList("META-INF", xs @ _*) => MergeStrategy.discard
  case x => MergeStrategy.first
}

但是，当我尝试使用 H2OContext.getOrCreate() ，sbt抛出 Caused by: scala.reflect.internal.FatalError: package scala does not have a member Int 当我使用 run sbt控制台中的命令。但是，当我直接运行main方法时，代码运行得很好。
以下是堆栈跟踪：

与这个问题相关的其他答案似乎指向scala和play框架之间的问题（在我的应用程序中，我并不直接依赖于这个框架）。有办法解决这个问题吗？这是scala或起泡水的问题吗？
