Scala 如何重命名导入的Maven包的groupID以删除连字符？

scala maven intellij-idea apache-flink

Scala 如何重命名导入的Maven包的groupID以删除连字符？,scala,maven,intellij-idea,maven-3,apache-flink,Scala,Maven,Intellij Idea,Maven 3,Apache Flink,我正在研究如何创建一个简单的应用程序，从文件中读取数据并对其进行过滤。我使用Scala作为编写Flink应用程序的语言，最终代码如下所示： package com.dataartisans.flinktraining.exercises.datastream_scala.basics import com.dataartisans.flinktraining.exercises.datastream_java.sources.TaxiRideSource import com.dataarti

我正在研究如何创建一个简单的应用程序，从文件中读取数据并对其进行过滤。我使用Scala作为编写Flink应用程序的语言，最终代码如下所示：

package com.dataartisans.flinktraining.exercises.datastream_scala.basics

import com.dataartisans.flinktraining.exercises.datastream_java.sources.TaxiRideSource
import com.dataartisans.flinktraining.exercises.datastream_java.utils.GeoUtils
import org.apache.flink.api.java.utils.ParameterTool
import org.apache.flink.streaming.api.TimeCharacteristic
import org.apache.flink.streaming.api.scala._

object RideCleansing {

  def main(args: Array[String]) {

    val params = ParameterTool.fromArgs(args)
    val input = params.getRequired("input")

    val maxDelay = 60
    val speed = 600 

    val env = StreamExecutionEnvironment.getExecutionEnvironment
    env.setStreamTimeCharacteristic(TimeCharacteristic.EventTime)

    val rides = env.addSource(new TaxiRideSource(input, maxDelay, speed))

    val filteredRides = rides
      .filter(r => GeoUtils.isInNYC(r.startLon, r.startLat) && GeoUtils.isInNYC(r.endLon, r.endLat))

    filteredRides.print()
    env.execute("Taxi Ride Cleansing")
  }

}

根据建议，我已将以下内容添加到POM文件中：

<dependency>
  <groupId>com.data-artisans</groupId>
  <artifactId>flink-training-exercises</artifactId>
  <version>0.10.0</version>
</dependency>

它似乎正在查找包

com.dataartisans

，但它是作为带有连字符的

com.dataartisans

导入的，因此找不到它。如果我的主IDE是IntelliJ，如何解决此问题

以下是

答案很简单：我将依赖项放在pom文件的错误部分，另一组依赖项是概要文件的一部分。粗心的错误…
