根据 android 构建类型运行特定的 gradle 任务

Question

我正在尝试根据构建类型（调试或发布）运行特定任务/操作。

android {
    applicationVariants.all { variant ->
        println "buildType.name is $buildType.name"
    }
}

但无论我运行 assembleDebug 还是 assembleRelease，我的代码都会针对两种构建类型执行：

10:56:20 PM: Executing external task 'assembleDebug'...
Configuration on demand is an incubating feature.
buildType.name is debug
buildType.name is release

BUILD SUCCESSFUL

Total time: 10.657 secs
10:56:31 PM: External task execution finished 'assembleDebug'.

为什么会这样？

检测当前构建类型的正确方法是什么？

Answer 1

你可以让构建依赖于不同构建的任务

buildTypes {
    release {
        build.dependsOn 'mySweetReleaseTask'
    }
    debug {
        build.dependsOn 'mySweetDebugTask'
    }
}

或者

buildTypes {
    release {
        project.getTasks().getByName('build').dependsOn('mySweetReleaseTask')
    }
    debug {
        project.getTasks().getByName('build').dependsOn('mySweetDebugTask')
    }
}

如果您希望您的任务在特定时间运行，例如在测试期间，您可以将'build' 替换为'check'。此配置块在构建实际开始之前的配置阶段（执行阶段）进行评估。
