Old question: sbt - object is not a member of package

[Zhan Wang]

Hi I'm new to scala and sbt. I wrote some test code and ran into some old question - object is not a member of package. I searched everywhere but got no luck. Below is my code:

########### build.sbt ############
name := "Test Codes"

version := "1.0"

scalaVersion := "2.10.4"

libraryDependencies ++= Seq(
  "org.apache.spark" %% "spark-core" % "1.2.0",
  "commons-io" % "commons-io" % "2.4",
  "com.google.code.gson" % "gson" % "2.2.4",
  "org.la4j" % "la4j" % "0.4.9"
)

javacOptions ++= Seq("-source", "1.7", "-target", "1.7")


############  scala code ##############

package app.mycompany

import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
import app.mycompany.DataPrepSpark

object TrainModels {

  def runTraining(input: String, output: String) = {
    val conf = new SparkConf().setAppName("Naive Bayes with Spark")
    val sc = new SparkContext(conf)

    val rawData = sc.textFile(input)
    val groupedData = rawData groupBy { G =>
      G.split("\t")(0)
    }

    val models = groupedData map { G =>
      DataPrepSpark.processData(G._1, G._2.toArra, 5)
    }

    models.saveAsTextFile(output)
  }

  def main(args: Array[String]) = {
    runTraining(args(0), args(1))
  }
}

############## java code ###############

packageapp.mycompany;

import com.google.gson.*;
import org.apache.commons.io.FileUtils;
import org.la4j.io.MatrixMarketStream;
import org.la4j.matrix.Matrix;

import java.lang.reflect.Type;
import java.math.BigDecimal;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class Test
{

    public static String processData(String id, String[] rows, int length)
    {   
        System.out.println("TESTING....................");
        System.out.println(length);
        return id;
    }
}



Scala and Java codes are in the same package but the java class just can't be found...

Thanks!

Maybe it is because you've named your class Test but calls it like DataPrep Spark?
