如何過濾和執行特定的Gradle任務？

Question

我的Android項目已經配置了不同的產品口味：

productFlavors { 
    devtracking { 
     dimension trackingFlavorDimension 
    } 

    livetracking { 
     dimension trackingFlavorDimension 
    } 

    stagingwebservice { 
     dimension webserviceFlavorDimension 
    } 

    livewebservice { 
     dimension webserviceFlavorDimension 
    } 

    playstore { 
     dimension brandDimension 
    } 

    fdroid { 
     dimension brandDimension 
    } 
} 

我怎麼能寫，只有建立release打造爲devtracking味道的任務嗎？ 「過濾器」已準備就緒 - 我如何才能真正執行已過濾的任務？請注意，現在「過濾器」已在配置時執行。

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 
     } 
    } 
} 

Answer 1

隨着Selvin和mirceanis有很大的幫助，我終於想出了這個解決方案：

// 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") 

可能的改進：移動到一個自定義任務類buildSrc。

task installDevtrackingReleaseFlavors() { 
    android.applicationVariants.all { v -> 
     if (v.name.endsWith('DevtrackingRelease')) { 
      String name = v.name.capitalize() 
      dependsOn "install$name" 
     } 
    } 
}
