Ant <exec> output not captured in property

I am trying to get the output of an Ant execution command into an output property and echo that property. We should be able to view the output of the command. I have used the below code, but I am not able to view the output of the Ant execution.

<exec executable="${exe.baroverride}"
      spawn="false"
      failonerror="true"
>
    <redirector outputproperty="baroverride.out"
        errorproperty="baroverride.err"/>
</exec>
<logmsg message="Bar Override Output for the bar file ${iib.build.target.bar.filename} ${baroverride.out}"/>

First, there is no <logmsg> task included with Ant. <logmsg> may be from a custom <macrodef> or <taskdef>. We won't be able to help you with how <logmsg> works unless you provide the code for it.

Second, the <redirector> splits the output into two properties...

 <redirector outputproperty="baroverride.out"
     errorproperty="baroverride.err"/>

...however, the <logmsg> call only references baroverride.out...

<logmsg message="... ${baroverride.out}"/>

If <exec> wrote to baroverride.err, the above <logmsg> call won't show it.

Consider deleting the <redirector> altogether and use the outputproperty attribute of <exec> instead...

<exec executable="${exe.baroverride}"
      spawn="false"
      failonerror="true"
      outputproperty="baroverride.out"
/>
<echo>baroverride.out: ${baroverride.out}</echo>
