gradle-从命令行调用时未执行doLast闭包

在我的build.gradle中，我有以下代码行：

    task aExecutionTask << {

    println 'hello says aExecutionTask, via the execution phase'

}



task aConfigurationTask{

    println 'hello says aConfigurationTask, via the configuration phase'
    doLast{
        println 'im last to get done'

    }

}

---

为什么它不打印我的doLast声明？它显然运行了任务“aConfigurationTask”，但没有运行它的doLast。那么，我是否理解配置任务已配置但未执行？这就是概念吗？

在配置阶段对代码进行评估。因此，在配置任务时，任务并未实际执行<代码>doLast块将在执行任务后调用。使用您的代码，可以通过不提供命令（任务的配置）看到这一点。然后调用任务，即任务的执行，并调用任何

doLast

闭包

执行时，将调用

doLast

块。以下是一个例子：

$ gradle aExecutionTask
Configuration on demand is an incubating feature.
hello says aConfigurationTask, via the configuration phase
:aConfigurationTask
im last to get done
:aExecutionTask
hello says aExecutionTask, via the execution phase

task aConfigurationTask {

    doLast {
        println 'im last to get done'
    }
}
