在“之后运行渐变任务X”；“已连接的AndroidTest”；任务成功了

我有一个gradle

taskX

，我想在

connectedAndroidTest

任务完成后运行，但是只有在所有测试都通过

connectedAndroidTest

时才运行

---

如何实现这一点？

您正在描述任务依赖关系。您可以定义依赖于另一个任务的任务，并因此在执行时触发另一个任务：

task taskX(dependsOn: 'connectedAndroidTest') << {
   //do something
}

您需要利用特定任务的状态检查。以下是如何做到这一点：

task connectedAndroidTest << {
  logger.lifecycle("Running $name")
  if (project.hasProperty('lol')) {
    throw new Exception('lol')
  }
}

task taskX << {
  def failure = tasks.connectedAndroidTest.state.failure
  if(!failure) {
    logger.lifecycle("$name is finalizer")
  } else {
    logger.lifecycle("$tasks.connectedAndroidTest.name failed, nothing to do.")
  }
}

connectedAndroidTest.finalizedBy(taskX)

输出将是：

:connectedAndroidTest
Running connectedAndroidTest
:taskX
taskX is finalizer

This build could be faster, please consider using the Gradle Daemon: https://docs.gradle.org/2.8/userguide/gradle_daemon.html

当：

运行，则输出为：

:connectedAndroidTest
Running connectedAndroidTest
:connectedAndroidTest FAILED
:taskX
connectedAndroidTest failed, nothing to do.

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/opal/tutorial/stackoverflow/34797260/build.gradle' line: 4

* What went wrong:
Execution failed for task ':connectedAndroidTest'.
> lol

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

在这种情况下，

finalizedBy

是不够的。

gradle cAT -Plol

:connectedAndroidTest
Running connectedAndroidTest
:connectedAndroidTest FAILED
:taskX
connectedAndroidTest failed, nothing to do.
