如何将命令行参数传递给 Gradle Kotlin DSL

Question

这是来自 Groovy 的示例，它完全代表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
    }
}

此示例的来源是 here - option 3。

如何在 Kotlin DSL 中读取传递和读取 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

Answer 2

我像这样检索了我的任务的参数（build.gradle.kts 和 Kotlin DSL）：

tasks.create("myCustomTask") {
  doLast {
    val myArg = properties["myArgName"]
    // OR a more verbose form:
    val myArg = project.properties["myArgName"]
  }
}

./gradlew myCustomTask -PmyArgName=hello
