ANT 脚本处理 exec 的返回值 [英] ANT Script handling Return value from exec

问题描述

这就是场景.我有

<target name="test">
  <property file="blah"></property>
  <exec dir="" executable="trast.exe" resolveexecutable="true" spawn="true">
  </exec>
</target>     

<!-- So now I have the second target that uses Return value from first target -->
<target name="test2">
  <property file="blah"></property>
  <exec dir="" executable=RETURN VALUE resolveexecutable="true" spawn="true">
  </exec>
</target>     

基本上我需要一种方法来在下一个目标中使用第一个目标的结果.我在网上查看，一种解决方案似乎是解析输出.但是有没有办法不解析就得到它?

Basically I need a way to use the result from first target in the next target. I looked online and one solution seems to be is to parse output. But is there a way to get it without parsing?

谢谢

推荐答案

exec 任务有一个 outputproperty.你能不能做这样的事情:

The exec task has an outputproperty. Could you do something like this:

<target name="test">
  <exec dir="" executable="trast.exe" resolveexecutable="true" spawn="true" outputproperty="blah">
  </exec>
</target>     

<!-- So now I have the second target that uses Return value from first target -->
<target name="test2">
  <exec dir="" executable="${blah}" resolveexecutable="true" spawn="true">
  </exec>
</target>

我使用 Ant 已经有一段时间了，我没有在这台机器上安装它，但我似乎记得做过类似上面的事情.

It's been a while since I used Ant and I don't have it installed on this machine, but I seem to recall doing something like the above.

或者也许使用 resultproperty?
