分级自定义任务执行阶段

Question

https://docs.gradle.org/current/userguide/custom_tasks.html

class GreetingTask extends DefaultTask {
    @TaskAction
    def greet() {
        println 'hello from GreetingTask'
    }
}

task hello(type: GreetingTask)

如何使此任务在执行阶段运行？正在传递一个空闭包

<< {

}

唯一的解决办法？

`build.dependsOn(hello)`

但是hello任务似乎是在构建的配置阶段调用的。

Answer 1

将以下内容添加到build.gradle文件中：

class GreetingTask extends DefaultTask {
    @TaskAction
    def greet() {
        println 'hello from GreetingTask'
    }
}

task hello(type: GreetingTask) {
    println "This is the configuration phase"

    doFirst {
        println "This is the execution phase"
    }
}

现在执行gradle hello。您将看到的输出是

This is the configuration phase
:hello
This is the execution phase
hello from GreetingTask

BUILD SUCCESSFUL

如您所见，任务的输出发生在doFirst()之后，这肯定发生在执行阶段。
