> This section of build.xml behaves differently between Ant 1.6.5 and Ant 1.7.0:
> {code:xml}
> <touch datetime="01/25/1971 2:00 pm">
> <fileset dir="${conf.dir}" includes="**/*.template"/>
> <fileset dir="${contrib.dir}" includes="**/*.template"/>
> </touch>
> {code}
> In Ant 1.6.5, if the fileset is empty (which it is if you're building from a
> released tar.gz distribution) then this section silently passes.
> In Ant 1.7.0, if the fileset is empty, the following error is raised and the
> build stops:
> {quote}
> BUILD FAILED
> /home/ndaley/Downloads/hadoop-0.15.1/build.xml:151: Specify at least one
> source--a file or resource collection.
