Re: Returning data from an Ant task?

[Erik Hatcher]

The convention for tasks that need to set the value of a property (see 
the source code for the <property> task itself) is for it to take the 
name of a property as one of its attributes (like <property name="..." 
...>) and call setNewProperty(name, value).

So in your example, it'd look like this, instead of the <property> line 
you provided:

        <getversion property="MyVersion" fileName="..."/>

I'm writing a custom ant task that parses a text file and I'd like to 
somehow pass the results back to the ant process. Is it possible to 
return an "output parameter" string value to an ant process? Ideally 
I'd like to do something like:
<target name="getversion" description="Retrieves the version of the 
product build out of the version file.">
   <taskdef name="getversion" classname="GetVersion" 
classpath="MyAntExtension.jar"/>
   <property name="MyVersion" value={getversion 
fileName="c:\work\AntExtensions\EXT_VERSION"} />
</target>
?
