Dropwizard IntelliJ安装问题

Question

我正在尝试安装Dropwizard hello world应用程序并遇到问题。这里是堆栈跟踪：

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.example.HelloWorldApplication$.main(HelloWorldApplication.scala:18) 
    at com.example.HelloWorldApplication.main(HelloWorldApplication.scala) 

这里是我的应用程序：

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) 
    } 
} 

我运行的IntelliJ这些参数的应用程序：server src/main/resources/config.yml

任何提示，调试和得到适当的设置会有帮助。

通过转到Project Structure> Artifacts并添加项目jar，在Scala项目中生成一个jar文件。
