我正在intellij中进行spark+scala+sbt项目设置。

Scala Version: 2.12.8
    SBT  Version:  1.4.2
    Java Version:  1.8

build.sbt文件：

name := "Spark_Scala_Sbt"
  version := "0.1"
   scalaVersion := "2.12.8"
    libraryDependencies ++= Seq(
   "org.apache.spark" %% "spark-core" % "2.3.3",
  "org.apache.spark" %% "spark-sql" % "2.3.3"
)

scala文件：

import org.apache.spark.sql.SparkSession

object FirstSparkApplication extends App {
  val spark = SparkSession.builder
    .master("local[*]")
    .appName("Sample App")
    .getOrCreate()
  val data = spark.sparkContext.parallelize(
Seq("I like Spark", "Spark is awesome", "My first Spark job is working now and is counting down these words")
  )
  val filtered = data.filter(line => line.contains("awesome"))
  filtered.collect().foreach(print)
}

但它会显示以下错误消息：

1. Cannot resolve symbol apache.
2. Cannot resolve symbol SparkSession
3. Cannot resolve symbol sparkContext
4. Cannot resolve symbol filter.
5. Cannot resolve symbol collect.
6. Cannot resolve symbol contains.

我应该在这里换什么？
