删除向导智能设置问题

Question

我正在尝试设置 Dropwizard hello world 应用程序并遇到问题。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 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)
}
}

我在 IntelliJ 中使用这些参数运行应用程序：server src/main/resources/config.yml

任何正确调试和设置的提示都会有所帮助。
