Making build-war non-interactive

[Rod Widdowson]

>    <target name="prompttarget" if="idp.ask.target">
>        <TGT>prompttarget</TGT>
>        <fail if="idp.noprompt">Input needed, silence demanded</fail>
>        <!--<input message="Installation Directory:" addproperty="idp.target.dir" defaultvalue="${idp.target.default}" />-->
>        <property name="idp.target.dir" value="${idp.target.default}" />
>    </target>

This snippet is from the V3 ant script.  

This should have been update on upgrade, but wasn't [2].   All the properties you need are documented at the top of that file.  For
what its worth the property you want is also documented [1] , but it took me 30 minutes to get hold of the link (and I wrote the
code) so I'll take an action to fix that [3].

Thanks for bringing this bug to my attention,

Rod
