Hi Marcel,
I run the main method (Right click on the example folder and select
the option use as source folder) and I have received the same error:

Setting up recommender and model repository (downloads search index
the first time).
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for
further details.
