找不到参数springBoot（）的方法-使用Kotlin的Spring Boot

我尝试使用Kotlin创建第一个Spring Boot应用程序。因此，也许我犯了一些明显的错误或类似的错误。

我的 gradle.build 是：

buildscript {
    ext.kotlin_version = '1.0.5-2'
    ext.spring_boot_version = '1.4.2.RELEASE'
    repositories {
        jcenter()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "org.springframework.boot:spring-boot-gradle-plugin:$spring_boot_version"
    }
}

apply plugin: 'idea'
apply plugin: 'kotlin'
apply plugin: 'application'

jar {
    basename = 'rest-voter'
    version = '0.1.0'
}

springBoot {
    mainClass = 'ru.hixon.Application'
}

repositories {
    jcenter()
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    compile "org.springframework.boot:spring-boot-starter-web:1.4.2.RELEASE"
    TESTCompile 'junit:junit'
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.13'
}

该 错误 是：

C:\Users\Desktop\rest-voter>gradlew build

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\Desktop\rest-voter\build.gradle' line: 22

* what went wrong:

我的 主要课程 是：

package ru.hixon

import org.springframework.boot.SpringApplication
import org.springframework.boot.autoconfigure.SpringBootApplication

@SpringBootApplication
open class Application {

}

fun main(args: Array<String>) {
    SpringApplication.run(Application::class.java,*args)
}

而这里是我的应用程序的完整的代码。
