在ant中无条件执行任务? [英] Unconditionally execute a task in ant?

问题描述

我正在尝试定义一个任务，该任务在目标完成执行时发出(使用回显)消息，而不管该目标是否成功.具体来说，目标执行一个任务来运行一些单元测试，我想发出一条消息，指示结果可用的位置:

I'm trying to define a task that emits (using echo) a message when a target completes execution, regardless of whether that target was successful or not. Specifically, the target executes a task to run some unit tests, and I want to emit a message indicating where the results are available:

<target name="mytarget">
  <testng outputDir="${results}" ...>
    ...
  </testng>
  <echo>Tests complete.  Results available in ${results}</echo>
</target>

不幸的是，如果测试失败，任务将失败并中止执行.所以只有在测试通过时才会输出消息 - 与我想要的相反.我知道我可以把任务放在任务之前，但这会让用户更容易错过这条消息.我正在尝试做的事情可能吗?

Unfortunately, if the tests fail, the task fails and execution aborts. So the message is only output if the tests pass - the opposite of what I want. I know I can put the task before the task, but this will make it easier for users to miss this message. Is what I'm trying to do possible?

更新:事实证明我很笨.我的 <testng> 中有haltOnFailure="true"任务，这解释了我所看到的行为.现在的问题是，即使测试失败，将其设置为 false 也会导致整个 ant 构建成功，这不是我想要的.下面使用任务的答案看起来可能是我想要的..

Update: It turns out I'm dumb. I had haltOnFailure="true" in my <testng> task, which explains the behaviour I was seeing. Now the issue is that setting this to false causes the overall ant build to succeed even if tests fail, which is not what I want. The answer below using the task looks like it might be what I want..

推荐答案

解决您的问题的方法是将 failureProperty 与 testng 的 haltOnFailure 属性结合使用像这样的任务:

The solution to your problem is to use the failureProperty in conjunction with the haltOnFailure property of the testng task like this:

<target name="mytarget">
  <testng outputDir="${results}" failureProperty="tests.failed" haltOnFailure="false" ...>
    ...
  </testng>
  <echo>Tests complete.  Results available in ${results}</echo>
</target>

然后，当您希望构建失败时，您可以在其他地方添加如下蚂蚁代码:

Then, elsewhere when you want the build to fail you add ant code like this:

<target name="doSomethingIfTestsWereSuccessful" unless="tests.failed">
   ...
</target>

<target name="doSomethingIfTestsFailed" if="tests.failed">
   ...
   <fail message="Tests Failed" />
</target>

然后，您可以在希望 ant 构建失败的地方调用 doSomethingIfTestsFailed.

You can then call doSomethingIfTestsFailed where you want your ant build to fail.
