Lemmatization using StanfordNLP in ML 2.0

[janardhan shetty]

Hi,

I am trying to use lemmatization as a transformer and added belwo to the
build.sbt

 "edu.stanford.nlp" % "stanford-corenlp" % "3.6.0",
    "com.google.protobuf" % "protobuf-java" % "2.6.1",
    "edu.stanford.nlp" % "stanford-corenlp" % "3.6.0" % "test" classifier
"models",
    "org.scalatest" %% "scalatest" % "2.2.6" % "test"


Error:
*Exception in thread "main" java.lang.NoClassDefFoundError:
edu/stanford/nlp/pipeline/StanfordCoreNLP*

I have tried other versions of this spark package.

Any help is appreciated..
