sbt - object apache is not a member of package org

Question

I want to deploy and submit a spark program using sbt but its throwing error.

Code:

package in.goai.spark

import org.apache.spark.{SparkContext, SparkConf}

object SparkMeApp {
  def main(args: Array[String]) {
    val conf = new SparkConf().setAppName("First Spark")
    val sc = new SparkContext(conf)
    val fileName = args(0)
    val lines = sc.textFile(fileName).cache
    val c = lines.count
    println(s"There are $c lines in $fileName")
  }
}

build.sbt

    name := "First Spark"

    version := "1.0"

    organization := "in.goai"

    scalaVersion := "2.11.8"

    libraryDependencies += "org.apache.spark" %% "spark-core" % "1.6.1"

    resolvers += Resolver.mavenLocal

Under first/project directory

build.properties

bt.version=0.13.9

When I am trying to run sbt package its throwing error given below.

I have tried with extends to App too but no change.

Answer 1

Please remove resolvers += Resolver.mavenLocal from build.sbt. Since spark-core is available on Maven, we don't need to use local resolvers.

After that, you can try sbt clean package.
