You most likely have two different versions of Ant on your classpath.
>From your stacktrace my guess would be that there is an older ant.jar
on your classpath combined with a more recent ant-optional.jar.  This
old ant.jar most likely hides the one that belongs to your optional

FileUtil.getFileUtils has been added in the 1.7 codebase and is used
by several tasks and types, so my guess is that there is a 1.6.x
ant.jar somewhere on your system getting in the way.
