Does anyone else get this error when they run generate-entities

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
***ERROR*** [generate-entities] org/slf4j/impl/StaticLoggerBinder

I have been checking all the user forums and have copied the slf4j-jdk14-1.5.8.jar to $FORGE_HOME/lib in addition to copying the jdbc driver. But I still keep getting this error.

I even copied the other SLF4J implementation jars ( only one at a time) but it did not help.

I haven't found anyone else having this issue so was wondering if I am doing something incorrect and if anyone could give some tips would be great.
