jar - 在JAR中将Kotlin .kt类打包

Question

如何将HelloWorld.kt构建为JAR以便其运行？

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，它被声明为类，因此该方法不在顶级(？)上。还要包括kotlin运行时。

我需要手动为entry point创建一个带有MANIFEST.MF的Main-Class吗？

您应该为该任务使用诸如Gradle之类的构建工具。

在此示例中，将创建一个带有 list 的Jar条目:https://github.com/s1monw1/kotlin_vertx_example/blob/master/build.gradle.kts
