and here build file of child projectmysubproject

name := """mysubproject"""  version := "1.0-snapshot"  scalaversion := "2.11.1"  librarydependencies ++= seq("org.scalatest" %% "scalatest" % "2.2.1" % "test"withsources() withjavadoc(),                     "org.slf4j" % "slf4j-api" % "1.6.4",                 "org.elasticsearch" % "elasticsearch" % "1.6.0",                 "org.codehaus.groovy" % "groovy-all" % "2.4.0",                 "org.apache.lucene" % "lucene-expressions" % "4.10.4",                 "org.easymock" % "easymock" % "3.1" withsources() withjavadoc(),                 "org.mockito" % "mockito-all" % "1.9.5",                 "com.typesafe.akka" %% "akka-actor" % "2.3.6",                 "ch.qos.logback" % "logback-core" % "1.0.9",                  "com.github.nscala-time" %% "nscala-time" % "2.0.0",                  "net.liftweb" %% "lift-json" % "2.6+",                  "net.liftweb" %% "lift-json" % "2.6+")

and here code in parent project myparentproject created class named app/mypackagae/abc.scala here code 

  package mypackagae import mysubproject._ class abc { def helloabc()={   println(" root project ,  class abc ") } val test=new testing test.hellotesting() }

and in mysubproject created class in /mysubproject/src/main/scala-2.11/mysubproject/testing.scala here code 

package mysubproject //import parentprojectpackage._  import mypackagae._ //here  error not found: object mypackagae  class testing {    def hellotesting() ={     println("i subproject or child project , class testing")   } //and here want access class abc , method helloabc() eclipse not importing }
