您需要使用 finalizedBy 以及特定任务的状态检查。以下是如何完成的：

You need to utilize finalizedBy along with particular task's state checking. Here's how it can be done:

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)

现在如果运行：

Now if run with:

gradle cAT

输出结果为：

the output will be:

:connectedAndroidTest
Running connectedAndroidTest
:taskX
taskX is finalizer

BUILD SUCCESSFUL

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

何时：

When:

gradle cAT -Plol

运行，则输出为：

is run, then the output is:

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