如何将命令行参数传递给Gradle Kotlin DSL [英] How to pass command line argument to Gradle Kotlin DSL

问题描述

下面是Groovy的一个例子，它准确地表达了我想要实现的目标:

Here's an example from Groovy that represents exactly what I would like to achieve:

Command line:

./gradlew jib -PmyArg=hello

build.gradle.kts

task myTask {
    doFirst {
       println myArg
       ... do what you want
    }
}

此示例的来源为此处-选项3 .

如何在Kotlin DSL中读取pass并读取myArg值?

How can I read pass and read myArg value in Kotlin DSL ?

推荐答案

一段时间后找到答案:

build.gradle.kts

val myArg: String by project // Command line argument is always a part of project

task("myTask") {
    doFirst {
        if (project.hasProperty("myArg")) {
            println(myArg)
        }
    }
}

Command line:

gradle myTask -PmyArg=foo

Output:

$ gradle myTask -PmyArg=foo

> Task :myTask
foo
