为什么我不能在构建脚本中使用gradle任务connectedDebugAndroidTest？ [英] Why can't I use gradle task connectedDebugAndroidTest in my build script?

问题描述

我可以从我的构建脚本中引用 connectedCheck 任务（来自android插件）：

  connectedCheck.finalizedBy AndroidShowTestResults 
  

但试图使用 connectedDebugAndroidTest 也可以使用android插件）

  connectedDebugAndroidTest.finalizedBy AndroidShowTestResults 
  

给我

错误：（48，0）找不到属性'connectedDebugAndroidTest'

如果我尝试

 任务connectedDebugAndroidTest<< {print'123'} 
  

诅咒我

错误：无法添加任务'：app：connectedDebugAndroidTest'作为具有该名称的任务。

我不明白为什么我不能引用 connectedDebugAndroidTest ？

可用的gradle任务如下所示：

解决方案

android插件推迟添加几项任务，尤其是那些在其中具有buildType或风味名称的任务，直到配置阶段的非常晚期阶段。这反过来意味着如果您试图通过名称来引用这些尚未添加的任务，那么您可能会看到不存在类型的错误消息。如果您想添加延迟创建任务的依赖关系，那么您应该等到配置完成：

  gradle.projectsEvaluated {
 connectedDebugAndroidTest.finalizedBy AndroidShowTestResults 
 
 code $ <$ $ p 
 
 
或者，您可以将侦听器添加到task-图形事件，因此只要将任务添加到任务图中就可以完成任务： 
 
 
  tasks.whenTaskAdded {task - > 
 if（task.name =='connectedDebugAndroidTest'）{
 task.finalizedBy AndroidShowTestResults 
} 
} 
  
 
I can refer to connectedCheck task (which came from android plugin) from my build script:
connectedCheck.finalizedBy AndroidShowTestResults
But trying to use connectedDebugAndroidTest (which came from android plugin too)
connectedDebugAndroidTest.finalizedBy AndroidShowTestResults
gives me

  
Error:(48, 0) Could not find property 'connectedDebugAndroidTest' on project ':app'.
And if I try
task connectedDebugAndroidTest << {print '123'}
it curses me with

  
Error:Cannot add task ':app:connectedDebugAndroidTest' as a task with that name already exists.
I don't undestand why I cannot refer to connectedDebugAndroidTest?


Available gradle tasks are shown below:

解决方案
The android plugin defers the addition of several tasks especially those that have buildType or flavor names in them till a very late stage of the configuration phase. Which in turn means if you try to refer to these yet-to-be-added-tasks by name, you're likely to see a "does not exist" type error messages. If you want to add dependencies around deferred-created tasks, you should wait until configuration is complete:
gradle.projectsEvaluated {
    connectedDebugAndroidTest.finalizedBy AndroidShowTestResults
}
Alternatively, you can add a listener to task-graph events, so you can do stuff as soon as a certain task is added to task-graph:
tasks.whenTaskAdded { task ->
    if (task.name == 'connectedDebugAndroidTest') {
        task.finalizedBy AndroidShowTestResults
    }
}
