I found out what the problem was. I was somehow using a bad version of the
velocity-1.4-dev.jar artifact.
I found it strange that some of my Maven projects worked just fine and
others didn't. I've been managing different local artifact repositories so
I decided to swap out one for another and try generating site doco for my
projects. This is how I figured out that my velocity jar was bad.
FWIW, the bad velocity-1.4-dev.jar in my local repository is 368,352 bytes.
I replaced it with a good version of the velocity-1.4-dev.jar which is
359,924 bytes which is the same one up at ibiblio.org. I also had the MD5
hashes for both jars too (but I don't know if Maven validates artifact files
against their hashes.)
