Spark doesn't work with pureconfig

I am trying to use pureConfig and configFactory for my spark app config. here is my code:

import pureconfig.{loadConfigOrThrow}
object Source{
  def apply(keyName: String, configArguments: Config): Source = {
    keyName.toLowerCase match {
      case "mysql" =>
          val properties = loadConfigOrThrow[DBConnectionProperties](configArguments)
          new MysqlSource(None, properties)
      case "files" =>
        val properties = loadConfigOrThrow[FilesSourceProperties](configArguments)
        new Files(properties)
      case _ => throw new NoSuchElementException(s"Unknown Source ${keyName.toLowerCase}")
    }

  }
}

import Source
val config = ConfigFactory.parseString(result.mkString("\n"))
    val source = Source("mysql",config.getConfig("source.mysql"))

      

        
        
        
      

    

when i run it from IDE (intelliJ) or directly from java (i.e. java jar ...) it works fine.

But when I run it with spark-submit, it fails with the following error:

Exception in thread "main" java.lang.NoSuchMethodError: shapeless.Witness$.mkWitness(Ljava/lang/Object;)Lshapeless/Witness;

      

        
        
        
      

    

From a quick search, I found a similar question to this . which suggest that the reason for this is because both spark and pureConfig depend on Shapeless, but with different versions,

I tried to shade it as suggested in the answer

assemblyShadeRules in assembly := Seq(
  ShadeRule.rename("shapeless.**" -> "shadeshapless.@1")
    .inLibrary("com.github.pureconfig" %% "pureconfig" % "0.7.0").inProject
)

      

        
        
        
      

    

but it didn't work could it be for another reason? any idea what might work?

thank
