I am using Spark Scala. I am trying to upgrade scala to 2.12.15 and during build getting below issue.
scala.tools.nsc.Settings.nowarn()Lscala/tools/nsc/settings/AbsSettings$AbsSetting;
xsbt.Command$.getNoWarn(Command.scala:36)
xsbt.DelegatingReporter$.apply(DelegatingReporter.scala:19)
xsbt.CachedCompiler0.<init>(CompilerInterface.scala:75)
xsbt.CompilerInterface.newCompiler(CompilerInterface.scala:22)
What could be done?
