Error: Could not find or load main class in Scala

[Navin Manaswi]

I get the error : Error: Could not find or load main class org.test.spark.SparkTest :: when i run this code in Scala IDE

package org.test.spark
import org.apache.spark.mllib.tree.DecisionTree
import org.apache.spark.mllib.tree.model.DecisionTreeModel
import org.apache.spark.mllib.util.MLUtils

object SparkTest extends App {
// Load and parse the data file.
val data = MLUtils.loadLibSVMFile(sc, "TrainingNagios1.csv")
val splits = data.randomSplit(Array(0.7, 0.3))
val (trainingData, testData) = (splits(0), splits(1))

// Train a DecisionTree model.
//  Empty categoricalFeaturesInfo indicates all features are continuous.
val numClasses = 2
val categoricalFeaturesInfo = Map[Int, Int]()
val impurity = "gini"
val maxDepth = 5
val maxBins = 32

val model = DecisionTree.trainClassifier(trainingData, numClasses, categoricalFeaturesInfo,  impurity, maxDepth, maxBins)

}

How can we run this code ? (IS SBT must for it ?)

Hi,

Do you have error in the project ? (if any error in the project, then no class is generated)
