Question

我希望在taskX任务完成后运行我的gradle connectedAndroidTest，但只有在connectedAndroidTest传递所有测试时才会运行。

我怎么能做到这一点？

Answer 1

您需要利用finalizedBy以及特定任务的状态检查。以下是它的完成方式：

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：

gradle cAT

输出将是：

:connectedAndroidTest
Running connectedAndroidTest
:taskX
taskX is finalizer

BUILD SUCCESSFUL

Total time: 1.889 secs

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

当：

gradle cAT -Plol

运行

，然后输出为：

: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.

您正在描述任务依赖项。您可以定义依赖于另一个的任务，因此在执行时会触发另一个任务：

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

然后只需运行您的任务，connectedAndroidTest将首先执行：

gradle taskX

在＆＃34; connectedAndroidTest＆＃34;之后运行gradle任务X.任务成功
