Phing, call a command get its output into a property

Question

I have a script that can lookup and output or write my current release # to a text file. Now the only problem is how do I get this version number into a PHING property.

Right now my PHING target builds build.zip and built.tar, I would like it to build build-1.0.0.zip or whatever the version script decides the current version is. How can I do this? Will I have to create my own "task"?

You might need to create your own task for this. The task may look something like...

<?php
require_once "phing/Task.php";

class VersionNumberTask extends Task
{
    private $versionprop;

    public function setVersionProp($versionprop)
    {
        $this->versionprop = $versionprop;
    }

    public function init()
    {
    }

    public function main()
    {
        // read the version text file in to a variable
        $version = file_get_contents("version.txt");
        $this->project->setProperty($this->versionprop, $version);
    }
}

Then you would define the task in your build xml

<taskdef classname="VersionNumberTask" name="versiontask" />

Then call the task

<target name="dist">
    <versiontask versionprop="version.number"/>
</target>

At this point, you should be able to access the version number using ${version.number} throughout your build xml.

Hope this helps!
