ANT脚本处理来自exec的返回值

So this is the scenario. I have

所以这就是场景。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>

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?

基本上我需要一种方法来使用下一个目标中第一个目标的结果。我在网上看,一个解决方案似乎是解析输出。但有没有办法在没有解析的情况下获得它?

Thanks

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

exec任务有一个输出属性。你能做这样的事吗:

<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>

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.

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

Or maybe use resultproperty?

或者也许使用resultproperty?

The first executable return the name of the executable that you later have to run in test2, right?

第一个可执行文件返回您以后必须在test2中运行的可执行文件的名称,对吧?

So the first executable could write that name into a script file (e.g. batch file on Windows, shell file on Unix). The script would have a fixed name and your Ant script would just run it.

因此,第一个可执行文件可以将该名称写入脚本文件(例如,Windows上的批处理文件,Unix上的shell文件)。该脚本将具有固定名称,您的Ant脚本将运行它。
