Subject Re: I'm completely baffled by these documentation build errors on Apache Jenkins

Hi Bryan,

I see the ant plugin was changed / updated from 1.4 to 1.5 on the 25th of
May, but I don't know if that is a problem since the build is running so
seldom these days.
Could it be that one of the targets specified is being passed directly to
the underlying JVM due to a change in how they are processed by the plugin?
