ANT Script handling Return value from exec

Question

So this is the scenario. I have

<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?

Thanks

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>

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.

Or maybe use resultproperty?
