java.lang.NoClassDefFoundError：更好/ files /文件在spark-sbumit中用于scala代码

当我将程序导出到jar文件并执行它时，我得到一个java.lang.NoClassDefFoundError：better / files / File错误 .

我正在使用的代码如下 .

在此先感谢您的任何帮助

SBT

name := "testFunctions"

version := "1.0"

scalaVersion := "2.11.8"

libraryDependencies += "com.github.pathikrit" %% "better-files" % "2.17.1"
libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-core_2.11" % "2.1.0",
  "org.apache.spark" % "spark-sql_2.11" % "2.1.0",
  "com.github.pathikrit" %% "better-files" % "2.17.1"
)

initialize := {
  val _ = initialize.value
  if (sys.props("java.specification.version") != "1.8")
    sys.error("Java 8 is required for this project.")
}

Scala Code

/**
  * Created by cloudera on 7/23/17.
  */

import better.files.File._
import org.apache.spark.sql.SparkSession


object funcJM {


  val forDelete = (root/"/home/cloudera/Documents/fabo")
    .createIfNotExists()

  if (forDelete.exists)
    forDelete.delete()


  def main(args:Array[String]) : Unit = {

    val spark = SparkSession.builder
      .master("local")
      .appName("Get ForEx Data")
      .getOrCreate()



  }

}

Command line executing jar file

The Tree structure where the code live looks like below - 所以名为func的类存在于scala目录中

\main
    \java
    \resources
    \scala
        -funcJM(class)
    \scala-2.11
