Are you using Java 8?  Use Java 7 to build the site.  There is a bug in a 
component the CLIRR plugin uses. It is part of Apache Commons but Commons 
hasn’t had a release of it in a long, long time.  Gary and I are on the Commons 
PMC (actually, any Apache committer can get commit rights to Commons just by 
asking) and the discussion about this comes up from time to time.
