Scala版本flink在idea中打包报错

Question

这是我的代码
import org.apache.flink.streaming.api.scala._
import org.apache.flink.api.java.utils.ParameterTool

object Demo03WCStream {
def main(args: Array[String]): Unit = {

// 从外部命令中获取参数
val params: ParameterTool = ParameterTool.fromArgs(args)
val host: String = params.get("host")
val port: Int = params.getInt("port")

//创建流式处理API
val env = StreamExecutionEnvironment.getExecutionEnvironment
//设置全局并行度为1
env.setParallelism(1)

//禁用job chain
env.disableOperatorChaining()

val ds: DataStream[String] = env.socketTextStream(host, port)
val ds01: DataStream[(String, Int)] =
  ds.flatMap(_.split(" ")).setParallelism(2)
    .map((_, 1)).setParallelism(2).disableChaining()
    .keyBy(0)
    .sum(1).setParallelism(2)

ds01.print("wc")

env.execute("wc job")

}
}
这是报错
