Android 如何筛选和执行特定的Gradle任务？

我的Android项目配置了不同的产品风格：

productFlavors {
    devtracking {
        dimension trackingFlavorDimension
    }

    livetracking {
        dimension trackingFlavorDimension
    }

    stagingwebservice {
        dimension webserviceFlavorDimension
    }

    livewebservice {
        dimension webserviceFlavorDimension
    }

    playstore {
        dimension brandDimension
    }

    fdroid {
        dimension brandDimension
    }
}

如何编写只为

devtracking

flavor构建

release

build的任务？“过滤器”准备就绪-我如何实际执行过滤后的任务？注意，现在“过滤器”已经在配置时执行

task assembleDevtrackingRelease {
    description "Assembles all Devtracking release builds."
    group = "Build"
    android.applicationVariants.all { variant ->
        if (variant.name.contains("DevtrackingRelease")) {
            println(variant.name)
            // TODO Execute this variant
        }
    }
}

在Selvin和mirceanis的大力帮助下，我终于想出了这个解决方案：

// Creates a parent task for a set of sub tasks.
// Sub tasks are collected based on the given task name part.
def createVariantBatchTask(taskNamePart, taskPrefix = "assemble", taskGroup = "Build") {
    String taskName = "${taskPrefix}${taskNamePart.capitalize()}"
    Task task = tasks.create(taskName)
    task.description "${taskPrefix.capitalize()}s all $taskName builds."
    task.group taskGroup

    android.applicationVariants.all { variant ->
        if (variant.name.toLowerCase().contains(taskNamePart.toLowerCase())) {
            Task variantTask = tasks.findByName("${taskPrefix}${variant.name.capitalize()}")
            if (variantTask != null) {
                task.dependsOn variantTask
            }
        }
    }
}

createVariantBatchTask("devtrackingRelease")
createVariantBatchTask("devtrackingDebug")

可能的改进：移动到

buildSrc

中的自定义任务类中

我不想要

install

任务。我不想在调用

/gradlew tasks

时自动运行它。这看起来是一个不错的方法。。。将安装更改为组装，则此任务应运行所有

assemblexxxxxxdevtrackingrelease

任务。。。这个答案看起来像是[Gradle Recipes for Android code]的副本（没有更改您的要求我不明白：哪一行执行变量特定的任务？此外，电子书声明我需要添加一个

doLast

块来执行命令。

// Creates a parent task for a set of sub tasks.
// Sub tasks are collected based on the given task name part.
def createVariantBatchTask(taskNamePart, taskPrefix = "assemble", taskGroup = "Build") {
    String taskName = "${taskPrefix}${taskNamePart.capitalize()}"
    Task task = tasks.create(taskName)
    task.description "${taskPrefix.capitalize()}s all $taskName builds."
    task.group taskGroup

    android.applicationVariants.all { variant ->
        if (variant.name.toLowerCase().contains(taskNamePart.toLowerCase())) {
            Task variantTask = tasks.findByName("${taskPrefix}${variant.name.capitalize()}")
            if (variantTask != null) {
                task.dependsOn variantTask
            }
        }
    }
}

createVariantBatchTask("devtrackingRelease")
createVariantBatchTask("devtrackingDebug")
