I'm trying to deploy the Apache Spark/Scala code to the GKE cluster, and it fails the Scala version issue.

I'm getting the below error in the DEV cluster using this maven command(mvn clean -P shadedbuild -B package)
Exception in thread "main" java.lang.NoSuchMethodError: 'scala.collection.immutable.ArraySeq scala.runtime.ScalaRunTime$.wrapRefArray(java.lang.Object[])'
If I use this maven command(mvn clean -B package) and get the below error.
java.io.IOException: Scala signature package has wrong version expected: 5.0 found: 5.2 in scala.collection.immutable.package
