I obtained the next error compiling my code in Scala. How can I fix this problem?
My java version is "1.8.0_231".
My scala version is: Scala code runner version 2.11.8 -- Copyright 2002-2016, LAMP/EPFL
[error] (commonsUtils / Compile / compileIncremental) Error compiling

My build.sbt contains the following lines:

val scalaVersion_ = "2.11.8"
lazy val commonDependencies = Seq(
"org.apache.spark" %% "spark-sql" % sparkVersion

)
lazy val commonSettings = Seq(
scalaVersion := scalaVersion_
My java version is "1.8.0_231".
This is inconsistent with what the stack trace is showing:
at java.base/java.lang.Thread.run(Thread.java:834)
The notion of "java.base/java.lang" is Java Modules thing, which started in Java 9. You can figure out how to change your IntelliJ configuration to use JDK 8 or use Scala 2.11.12 that works with JDK 11.
Change
val scalaVersion_ = "2.11.8"
to
val scalaVersion_ = "2.11.12"

I am trying to use scalatest for testing scalajs but it throwing exceptions. Not sure what could be the issue. Any suggestions, please? TIA.
Another thing that I would like to mention is that the following exception was being thrown even without any test file.

It looks like you need to install node.js. If it's already installed, make sure it is on your path.
i am trying to use scapegoat in scala 2.13.1
i have added sbt-scapegoat plugin in project/plugin.sbt
addSbtPlugin("com.sksamuel.scapegoat" %% "sbt-scapegoat" % "1.1.0")
here is my build.sbt
lazy val scala212 = "2.12.8"
lazy val scala213 = "2.13.1"
scalaVersion in ThisBuild := scala213
lazy val supportedScalaVersions = List(scala213, scala212)
crossScalaVersions := supportedScalaVersions
scapegoatVersion in ThisBuild := "1.3.11"
libraryDependencies := {
val VersionSchema = """(\d+)\.(\d+)\.(\d+)""".r
scalaVersion.value match {
case VersionSchema("2", "12", "8") =>
libraryDependencies.value ++ Seq(
"ch.qos.logback" % "logback-classic" % "1.2.3",
"org.scalatest" %% "scalatest" % "3.1.0" % Test,
"io.gatling.highcharts" % "gatling-charts-highcharts" % "3.3.1" % "test",

,"com.sksamuel.scapegoat" %% "scalac-scapegoat-plugin"%"1.3.11"

when i run the scapegoat command in my sbt i am getting following exception

I have problems integrating spark with kafka. I using spark-streaming-kafka-0-8. I compile with SBT.
This is my code:
import org.apache.spark.SparkConf
import org.apache.spark.streaming._
import org.apache.kafka.clients.consumer.ConsumerRecord
import org.apache.kafka.common.serialization.StringDeserializer
import org.apache.spark.streaming.kafka._
object sparkKafka {
def main(args: Array[String]) {
val sparkConf = new SparkConf().setAppName("KafkaWordCount").setMaster("local[*]")
val ssc = new StreamingContext(sparkConf, Seconds(2))
val kafkaStream = KafkaUtils.createStream(ssc,
"localhost:2181", "spark stream", Map("customer" -> 2))
kafkaStream.print()
ssc.start()
ssc.awaitTermination()
}
}
I received this error:

This is my build.sbt file:
libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.2.0"
libraryDependencies += "org.apache.spark" % "spark-streaming_2.11" % "2.2.0"
libraryDependencies += "org.apache.spark" % "spark-streaming-kafka-0-10_2.11" % "2.2.0"
libraryDependencies += "org.apache.spark" % "spark-streaming-kafka-0-8_2.11" % "2.2.0"
How can I interated spark streaming with Kafka? I have a problem even spark-streaming-kafka-0-10....
Thanks
This is a version issue with Scala or Spark. Make sure you first are using Scala 2.11
If you are using Kafka 0.10, or higher (which if you've setup Kafka recently, and are only running it locally, then you likely would be), then you shouldn't be using kafka-0-8 package.
Do not mix spark-streaming-kafka-0-8 with spark-streaming-kafka-0-10
So, if you wanted to use 0-10, as answered previously, the package needs to be org.apache.spark.streaming.kafka010, not org.apache.spark.streaming.kafka
Also, note that the 0-8 does use Zookeeper (localhost:2181, for example), and 0-10 does not.
it might be a newbie question but i'm trying to learn more about scala in intellij. I firstly created a simple HelloWorld project that worked fine. Next i watched a tutorial to create a WordCount project, but i'm getting exception error that i can't figure out.
The error i get is:

Also, my code is:
package scala.SparkApps
import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
object WordCount {
def main(args: Array[String]): Unit = {
val inputFile = args(0)
val outputFile = args(1)
val conf = new SparkConf().setMaster("local(*)").setAppName("wordcount")
val sc = new SparkContext(Conf)
val input = sc.textFile(inputFile)
val words = input.flatMap(_.split(" "))
val counts = words.map(word => (word, 1)).reduceByKey(_+_)
counts.saveAsTextFile(outputFile)
}
}
Any ideas?
I was editing my Spark+Kafka application in Scala and when I tried to compile again I keep receiving the message Failing because of negative scalastyle result. When I change back my editions I still receive the same message.
What is this? How do I solve this error?

You can usually find the cause of this error in a file called scalastyle-result.xml, there you can find all the warnings and the possible errors causing this issue
it was because my project has these configurations on the build.sbt
lazy val compileScalastyle = taskKey[Unit]("compileScalastyle")
lazy val testScalastyle = taskKey[Unit]("testScalastyle")
lazy val root = (project in file("."))
.settings(commonSettings)

.settings(libraryDependencies ++= customLibraryDependencies)
.settings(excludeDependencies ++= commonExcludeDependencies)

testScalastyle := scalastyle.in(Test).toTask("").value,
(test in Test) := ((test in Test) dependsOn testScalastyle).value)
I removed and the error is no longer stoping the compilation.
