At the end I put a patch to extend <property> to get what I want to 
bugzilla:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21494

With that I can write:

<property name="file" location="build" find="on"/>
to locate build in the project's base dir or its parents.

Yes, I can use javascript, but that is messy especially if I want to use 
that code from multiple files. In the mean time I wrap ant invocation 
into a shell script that does the search for all properties that I need.

Regards, Igor
