在JAR中打包Kotlin .kt类 [英] package Kotlin .kt class in a JAR

问题描述

如何构建 HelloWorld.kt 作为 JAR 以便它运行？

How do I build HelloWorld.kt as a JAR so that it runs?

thufir@dur:~/kotlin$ 
thufir@dur:~/kotlin$ kotlinc HelloWorld.kt --include-runtime -d HelloWorld.jar
error: invalid argument: --include-runtime
info: use -help for more information
thufir@dur:~/kotlin$ 
thufir@dur:~/kotlin$ 
thufir@dur:~/kotlin$ kotlinc HelloWorld.kt -d HelloWorld.jar

thufir@dur:~/kotlin$ 
thufir@dur:~/kotlin$ java -jar HelloWorld.jar 
no main manifest attribute, in HelloWorld.jar
thufir@dur:~/kotlin$ 
thufir@dur:~/kotlin$ cat HelloWorld.kt 
import kotlin.jvm.JvmStatic

object HelloWorld {
    @JvmStatic
    public fun main(args: Array<String>) {
        println("Hello, world!" + args[0])
    }
}
thufir@dur:~/kotlin$ 

请注意它被声明为一个类，因此该方法不在顶层（？）。想要包含 kotlin 运行时。

Note that it's declared as a class, and so the method is not on the top level(?). Would want to include the kotlin runtime as well.

我是否需要手动创建 MANIFEST.MF Main-Class /jar/appman.htmlrel =nofollow noreferrer>切入点？

Do I need to manually create a MANIFEST.MF with Main-Class for the entry point?

推荐答案

你应该使用像Gradle这样的任务构建工具。

You should use a build tool like Gradle for that task.

在这个例子中，正在创建一个带有Manifest条目的Jar： https://github.com/s1monw1/kotlin_vertx_example/blob/master/build.gradle.kts

In this example, a Jar with Manifest entry is being created: https://github.com/s1monw1/kotlin_vertx_example/blob/master/build.gradle.kts
