Set ant property by invoking a shell script?

Question

Is there any way to set an ant property by capturing the output of a shellscript? (or another ant task)

Something like this:

<property name="foo">
    <value>
        <exec executable="bar" />
    </value>
</property>

Thanks!

Answer 1

It seems that exec task has an outputproperty-property, like so:

<exec executable="bar" outputproperty="foo" />

Answer 2

From the ANT exec task

1. Set the output attribute : Name of a file to which to write the output.
2. As Marble has suggested - set the outputproperty

When I tested they came out to be mutually exclusive. So set only 1 of them at a time.
