Question

我正在尝试构建一个简单的应用程序，它将使用KPL向Kinesis生成消息。我在scala中写这个，并收到一条我似乎无法弄清楚的错误信息。我的代码如下：

import java.nio.ByteBuffer

import com.amazonaws.services.kinesis.producer.{KinesisProducer, KinesisProducerConfiguration}

object KinesisStream extends App{
  ProduceToKinesis()

  def ProduceToKinesis(): Unit ={

    val config = new KinesisProducerConfiguration()
    val kinesis = new KinesisProducer(config)
    val data = ByteBuffer.wrap("myData".getBytes("UTF-8"))

    kinesis.addUserRecord("TestStream", "myPartitionKey", data)
  }
}

它失败了

val kinesis = new KinesisProducer(config)

，错误消息为：

我的Build.SBT看起来像这样：

name := "Kinesis"

version := "1.0"

scalaVersion := "2.11.8"

libraryDependencies += "com.amazonaws" % "amazon-kinesis-producer" % "0.12.1"

无法将原生二进制文件复制到临时目录Kinesis KPL
