Scala 在Ubuntu上运行Intellij中的Spark时出错

当我运行下面的代码时，我得到一个错误，它指向注释指示的行。我为Spark带来了JAR文件。在我编写代码时，就如何编写Spark代码提出了一些建议，因此IDE似乎能够识别Spark库。这是用Scala编写的，我对Scala和Spark都是新手。否则，Scala在IDE中运行良好

import org.apache.spark.sql.SparkSession

object Spark {
  def main(args: Array[String]): Unit = {
    val logFile = "/home/thomaswolff/ubuntu/spark-2.1.0-bin-hadoop2.7/LICENSE"
    val spark = SparkSession.builder.appName("Simple Application").getOrCreate()
    val logData = spark.read.textFile(logFile).cache()
    val numAs = logData.filter(line => line.contains("a")).count()
    val numBs = logData.filter(line => line.contains("b")).count()
    println(s"Lines with a: $numAs, Lines with a b: $numBs")
    spark.stop()
  }

}

以下是在Intellij中运行代码时发生的错误：

[error] Total time: 1 s, completed Oct 8, 2019 5:51:42 PM

更新：我安装了Intellij 2018.2的旧版本，并像以前一样加载了JAR，但现在我遇到了以下错误：

Error: Could not find or load main class Spark
Caused by: java.lang.ClassNotFoundException: Spark

我知道问题出在哪里了。我的build.sbt设置不正确。以下是：

name := "sbt_spark_scala"

version := "0.1"

scalaVersion := "2.11.8"

val sparkVersion = "2.2.1"

libraryDependencies ++= Seq(
  "org.apache.spark" %% "spark-core" % sparkVersion,
  "org.apache.spark" %% "spark-graphx" % sparkVersion,
  "org.apache.spark" %% "spark-sql" % sparkVersion,
  "org.apache.spark" %% "spark-mllib" % sparkVersion,
  "org.apache.spark" %% "spark-hive" % sparkVersion,
  "org.apache.spark" %% "spark-streaming" % sparkVersion % "provided"
)

这段youtube视频帮了我很多忙：

您使用的是哪个版本的Scala插件和Intellij？Intellij版本是2019.2.3。请稍等Scala版本Scala版本是：Scala代码运行程序版本2.11.12您可以快速尝试的是使用较旧的Intellij IDE。您可以安装JetBrain工具箱，并使用它快速测试其他版本。我在这方面取得了一些成功。显然，最新版本的Scala插件与spark并不完全兼容。你能分享你的

build.sbt
