android dexDebug或dexRelease任务后如何执行gradle任务

问题描述

我想在Android构建过程中，在dexRelease或dexDebug任务之后运行Gradle任务来执行一些shell脚本.

I want to run a Gradle task to execute some shell scripts after dexRelease or dexDebug task during the android build.

我尝试了以下方法

task taskAfterDex(type:Exec) {

    workingDir '.'
    executable 'sh'
    args "-c", "source scriptskAfterDex.sh"
    ignoreExitValue true
    doLast {
        println "taskAfterDex completed"
    }
}


tasks.whenTaskAdded { task ->
    if (task.name == 'dexRelease') {
        task.dependsOn taskAfterDex
    }
}

但是没有获得执行阶段日志，或者在dexRelease/Debug之后它没有执行.

but am not getting the execution phase log or it's not executing after dexRelease/Debug.

推荐答案

您真正想要的是完成任务.另外，whenTaskAdded对于之前已添加的任务不起作用；使用all可能更安全:

What you actually want is a finalizer task. Also, whenTaskAdded doesn’t work for tasks that have already been added before; using all may be safer:

tasks.all { task ->
    if (task.name == 'dexRelease') {
        task.finalizedBy 'taskAfterDex'
    }
}

正如@Blaz在问题注释中指出的那样，您使用dependsOn的方法则相反:它将taskAfterDex作为dexRelease的依赖项添加，即taskAfterDex在之前运行 dexRelease.

As @Blaz has noted in the question comments, your approach with dependsOn does the opposite: it adds taskAfterDex as a dependency of dexRelease, i.e., taskAfterDex is run before dexRelease.
