Eclipse and Ant input tag

Ok, this is frustrating. In an Eclipse 2.1.3 "stock" install, the Ant input task tag would create a dialog box allowing the developer to enter information. In an Eclipse 3.0 "stock" installation, this doesn't work anymore, it just errors out:

Buildfile: C:\Documents and Settings\Rob\My Documents\Eclipse\Web Site - greener\build.xml
tryit:
[input] Enter something:
BUILD FAILED: C:\Documents and Settings\Rob\My Documents\Eclipse\Web Site - greener\build.xml:3: Failed to read input from Console.
Total time: 110 milliseconds


The XML involved isn't that hard, either:

<project name="TestInputTag" default="tryit">

	<target name="tryit">

		<input message="Enter something:"/>

    </target>

</project>

Hopefully, someone on the Eclipse newsgroups can answer my question regarding this. Maybe I'll need to write an Ant task tag - but that seems to be a bit silly.
