如何将命令行参数传递给Gradle Kotlin DSL

Question

下面是Groovy的一个例子，它准确地表达了我想要实现的目标：

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here - option 3。

如何在Kotlin DSL中读取通过和读取myArg值？

Answer 1

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
