sbt got error when run Spark hello world code?

I got the same error.

build.sbt

name := "Simple Project"  
version := "1.0"  
scalaVersion := "2.12.3"  
libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.2.0"  

just change scalaVersion to 2.11.8 or lower. And it works.

Your have an error in built.sbt file, you must change %% to %:

name := "Mpa"
version := "1.0"
scalaVersion := "2.11.8"
libraryDependencies += "org.apache.spark" % "spark-core" % "2.1.1"

%% asks Sbt to add the current scala version to the artifact

You can spark-core_2.11 with % to get the issue solved.

// https://mvnrepository.com/artifact/org.apache.spark/spark-core_2.11
libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.1.0"

Hope this helps!

I got the same error and resolved it by below steps. Basically, the filename did not match the sbt configuration.
- Check filename of the spark core jar in $SPARK_HOME/jars ( it is spark-core_2.11-2.1.1.jar).
- Install scala 2.11.11.
- Edit build.sbt to scalaVersion := "2.11.11".
