Dropwizard IntelliJ安装问题

Question

我正在尝试安装Dropwizard hello world应用程序，并遇到了一个问题。下面是堆栈跟踪：

objc[30585]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/java (0x1021cc4c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x1031fd4e0). One of the two will be used. Which one is undefined.
Exception in thread "main" java.lang.NullPointerException

    at com.fasterxml.jackson.databind.node.TreeTraversingParser.<init>(TreeTraversingParser.java:65)

    at io.dropwizard.Application.run(Application.java:72)
    at com.example.HelloWorldApplication$.main(HelloWorldApplication.scala:18)
    at com.example.HelloWorldApplication.main(HelloWorldApplication.scala)

这是我的申请：

package com.example

import io.dropwizard.Application
import io.dropwizard.setup.Bootstrap
import io.dropwizard.setup.Environment

class HelloWorldApplication extends Application[HelloWorldConfiguration] {
  override def run(configuration: HelloWorldConfiguration, environment: Environment): Unit = {
    val helloWorld = new HelloWorldResource()
    environment.jersey().register(helloWorld)
  }

  override def initialize(bootstrap: Bootstrap[HelloWorldConfiguration]): Unit = {}
}

object HelloWorldApplication {
  def main(args: Array[String]) = {
    new HelloWorldApplication().run(args)
  }
}

我在IntelliJ：server src/main/resources/config.yml中使用以下参数运行应用程序

任何调试和正确设置的提示都是有帮助的。

通过转到>工件并添加一个项目jar，在Scala项目中生成一个jar文件。
