Scala Flink ES连接未按预期编译

我的问题有点像描述的那样。 部分代码（实际上取自apache站点）如下所示

val httpHosts = new java.util.ArrayList[HttpHost]
httpHosts.add(new HttpHost("127.0.0.1", 9200, "http"))
httpHosts.add(new HttpHost("10.2.3.1", 9200, "http"))

val esSinkBuilder = new ElasticsearchSink.Builder[String](
  httpHosts,
  new ElasticsearchSinkFunction[String] {
    def createIndexRequest(element: String): IndexRequest = {
      val json = new java.util.HashMap[String, String]
      json.put("data", element)


      return Requests.indexRequest()
              .index("my-index")
              .`type`("my-type")
              .source(json)

如果我加上这三条语句，我得到的错误如下

import org.apache.flink.streaming.connectors.elasticsearch.ElasticsearchSinkFunction
import org.apache.flink.streaming.connectors.elasticsearch.RequestIndexer
import org.apache.flink.streaming.connectors.elasticsearch6.ElasticsearchSink

我犯了一个错误

object elasticsearch is not a member of package org.apache.flink.streaming.connectors
object elasticsearch6 is not a member of package org.apache.flink.streaming.connectors

若我不添加那个些导入语句，我会得到如下错误

import org.apache.flink.streaming.connectors.elasticsearch.ElasticsearchSinkFunction
import org.apache.flink.streaming.connectors.elasticsearch.RequestIndexer
import org.apache.flink.streaming.connectors.elasticsearch6.ElasticsearchSink

上面提到的堆栈流问题，一些函数已经扩展。我的理解是，flink.streaming.connectors.elasticsearch必须扩展到REST库中。1） 我的理解正确吗2）如果是，我可以完整地扩展吗3）如果我的理解错误，请给我一个解决方案

注意：我在build.sbt中添加了以下语句

libraryDependencies += "org.elasticsearch.client" % "elasticsearch-rest-high-level-client" % "7.5.2" ,
    libraryDependencies += "org.elasticsearch" % "elasticsearch" % "7.5.2",

流式连接器不是flink二进制发行版的一部分。您必须将它们与应用程序打包在一起

对于

elasticsearch6

，您需要添加

flink-connector-elasticsearch6_2.11

，您可以按照

libraryDependencies += "org.apache.flink" %% "flink-connector-elasticsearch6" % "1.6.0"

一旦这个jar成为构建的一部分，编译器就会找到缺少的组件。但是，我不知道此ES6客户端是否能与7.5.2版配合使用。

Flink Elasticsearch Connector 7

请看我提供的工作和详细的答案，这是用Scala编写的

我在build.sbt中添加了以下语句。libraryDependencies+=“org.apache.flink”%”flink-connector-elasticsearch6_2.11“%”1.9.0“%”提供了“由于类型的trait-elasticsearchsink函数中的方法进程，我得到以下错误，无法创建对象（x$1:String，x$2:org.apache.flink.api.common.functions.RuntimeContext，x$3:org.apache.flink.streaming.connectors.elasticsearch.RequestIndexer）未定义单元[error]新的ElasticsearchSinkFunction[String]{[error]^我不知道为什么flink docs for ES6中的Scala示例没有定义

过程

方法，但Java版本定义了。听起来可能需要这个方法。
