IDEA中Kotlin生成可执行文件
1，项目使用Gradle构建
2，在model的build.gradle中添加插件：

apply plugin: 'application'

mainClassName = "net.println.kotlin.HelloKt"     //注意文件名Kt结尾

，在ide右侧：Gradle->model name->Tasks->distribution->installDist双击即可执行任务
4，构建完毕，在./build/install/{modelName}/bin/下会生成bash脚本和bat脚本

import java.io.File

println("HelloWorld")

File(".").list().forEach(::println)
