老师您好，我运行以下代码：

import org.apache.spark.SparkContext
object WordCount{
 def main(args: Array[String]):Unit= {
   val inputFile =  "file:///Users/alex/Desktop/RLPL/test.txt"
   val sc = new SparkContext("local","WordCount")
   sc.setLogLevel("ERROR")
   val textFile = sc.textFile(inputFile)
   val wordCount = textFile.flatMap(line => line.split(",")).map(word => (word, 1)).reduceByKey((a, b) => a + b)
   wordCount.foreach(println)
 }
}

运行老报错：
Exception in thread "main" java.lang.NoSuchMethodError: scala.Predef$.wrapRefArray([Ljava/lang/Object;)Lscala/collection/mutable/WrappedArray;
	at org.apache.spark.SparkContext$.<init>(SparkContext.scala:2444)
	at org.apache.spark.SparkContext$.<clinit>(SparkContext.scala)
	at WordCount$.main(WordCount.scala:7)
	at WordCount.main(WordCount.scala)

我在pom文件中配置的版本是：

<properties>
   <spark.version>2.4.4</spark.version>
   <scala.version>2.11</scala.version>
</properties>

不知道是哪里出了问题
