PureConfig ConfigLoader in Scala - scala

Question

I am following this link to use pureconfig to load the data
https://pureconfig.github.io/docs/overriding-behavior-for-case-classes.html.
Here is my code
import com.typesafe.config.ConfigFactory
import pureconfig._
private case class SampleConf(foo: Int, bar: String)
object TestConfigLoad {
def main(args: Array[String]): Unit = {
loadConfig[SampleConf](ConfigFactory.parseString("{ FOO: 2, BAR: two }"))
}
}
When I run it , I am getting this error
Error:scalac: Error: scala.collection.immutable.$colon$colon.tl$1()Lscala/collection/immutable/List;
java.lang.NoSuchMethodError: scala.collection.immutable.$colon$colon.tl$1()Lscala/collection/immutable/List;
at shapeless.LazyMacros$DerivationContext$State.addDependency(lazy.scala:363)

You have to match the Scala versions. Cannot mix 2.10 (scala-library) and 2.11 (pureconfig_2.11).
Unless you have a good reason, use the latest stable version (2.12.8 currently)
