Re: howto redirect file content to ANT console to follow a build

[Markus Bauer-Sommerfeld]

I found a solution by my own:

I used a parallel task. One for the Matlab call and one for a tail -f 
command as daemon. tail -f is killed automatically, if Matlab has finished:

  <target name="all">
    <parallel>
      <exec dir="." executable="cmd.exe"
        output="out.log"
        logError="true"
        failonerror="true">
    <arg value="/c"/>
    <arg value="echo test1 &amp;&amp; sleep 1 &amp;&amp; echo test2 
&amp;&amp; sleep 1 &amp;&amp; echo test3"/>
      </exec>
      <daemons>
    <exec dir="." executable="tail.exe"
          logError="true"
          failonerror="true">
      <arg value="-f"/>
      <arg value="out.log"/>
    </exec>
      </daemons>
    </parallel>
  </target>
