Do
mvn site
then if successful do
mvn site-deploy
from your local machine in the root of your RAT checkout, this will scp the site file to /www/incubator.apache.org/rat/ on minotaur (people.apache.org).
If you have issues with 'mvn site' failing try running 'mvn clean' then 'mvn install package' before going back and running 'mvn site' again.
If you experience an Out of Memory error java.lang.OutOfMemoryError: Java heap space when running 'mvn site' try setting 'export MAVEN_OPTS=-Xmx512m' or for windows 'set MAVEN_OPTS=-Xmx512m' first on the command line (or in your profile) and then try 'mvn site' again. Only when 'mvn site' is successful should you then 'mvn site-deploy'
