For a specific file, you can use a combination of the <available> task and
the "unless" <target> attribute:
  <target name="copyFoo" depends="noFoo">
    <copy.../>
  </target>
  
  <target name="noFoo" depends="checkFoo" unless="foo.present">
    <fail message="Error: File foo not found."/>
  </target>
  <target name="checkFoo">
    <available file="foo" property="foo.present"/>
  </target>
