Okay, fixed now.

Chris, you will need to do ...

cd $FORREST_HOME/main
./build.sh clean
./build.sh

And probably best to also do 'forrest clean' in any place
where you have done 'forrest' e.g. in site-author directory.

Now edit the forrest.properties of each project (e.g. in
the site-author directory) to declare version 0.1 of the
projectInfo plugin.
project.required.plugins=...,...,
...,org.apache.forrest.plugin.input.projectInfo-0.1,...

Thanks again for reporting issues. It is being discussed
on the dev list.
