scala - ERROR when using SPARK : java.lang.NoClassDefFoundError: dispatch/Http -

-

when using spark-submit error happen: 

error executor: exception in task 0.0 in stage 137.0 (tid 35) java.lang.noclassdeffounderror: dispatch/http$

although have import lib (i'm using scala) : 

import dispatch._, defaults._

part of code :

def publishtonsq(data: string) = {         val topic = "post_similar_items_to_elasticsearch"         val host = "192.168.100.160:4151"         def myrequest = url(s"$host/pub?topic=$topic")         def myrequestasjson = myrequest.setcontenttype("application/json", "utf-8")         def mypostwithbody = myrequestasjson << data         val response = http(mypostwithbody ok as.string)         println(response)     }

this part of build.sbt :

scalaversion := "2.10.5"  librarydependencies += "org.apache.spark" %% "spark-core" % "1.6.1" librarydependencies += "org.apache.spark" %% "spark-mllib" % "1.6.1" librarydependencies += "org.json4s" %% "json4s-native" % "3.4.0" librarydependencies += "org.json4s" %% "json4s-jackson" % "3.4.0" librarydependencies += "org.scalaj" %% "scalaj-http" % "1.1.4" librarydependencies += "net.databinder.dispatch" %% "dispatch-core" % "0.11.2" resolvers += resolver.mavenlocal

any solution ?

the dependency not in jar, resolved if configure in java.lang.noclassdeffounderror: org/apache/spark/streaming/twitter/twitterutils
