Question

我用Java创建了Gradle任务：

class TestTask extends Exec {

    public TestTask() {

        doLast(new Action<Object>(){
            @Override
            public void execute(Object task) {
                System.out.println("Should be last ");
            }
        });

        doFirst(new Action<Object>(){
            @Override
            public void execute(Object task) {
                System.out.println("Should be first ");
            }
        });

        commandLine("echo", "Should be between");
    }
}

执行此任务，我希望得到

Should be first
Should be between
Should be last

但是我得到了

Should be between
Should be first
Should be last

我正在将插件从Groovy转换为Java，在Groovy中，按如下方式定义时，处理顺序符合预期：

task dofirsttest(type: Exec) {
    doFirst{
        println "Should be first"
    }
    doLast{
        println "Should be last"
    }
    commandLine "echo", "Should be between"
}

我的任务有问题吗？

Answer 1

commandLine("echo", "Should be between");处于任务的配置阶段。因此它将首先执行。看看：https://docs.gradle.org/current/userguide/build_lifecycle.html

Gradle任务的doFirst（）不会首先执行，而是在任务完成后执行
