For explicitly named files, run an <available> on them, and <fail> if the
property's not set. (If running 1.5, <fail unless="propname".../>.)

Define a <fileset>, <pathconvert> it to a property, and <fail> if the
property's not set -- ie., the <fileset> is empty (for 1.5Beta3 -- for
earlier versions, you'd need to include a <condition> that tests if the
property is equal to "").
