I'm new in Mahout and I have a week trying to run the book examples. The book recommends to use an IDE for this but Eclipse and Netbeans are having some troubles with the maven and slf4j installation thats why I tryed to use the ubuntu 13.04 terminal. Can anyone could help me with this?? I downloaded the source code from the 0.7 branch on the git repository and trying to make it work doing the following steps:
$sudo apt-get install maven (it installs the 3.0.4 version)$ mvn package (I think I have to modify the pom file but I'm not sure)$ mvn exec:java -Dexec.mainClass="mia.recommender.ch02.IREvaluatorIntro" -Dexec.args="src" command but when i run it it shows me this:[INFO] ------------------------------------------------------------------------

Thanks in advance!
i think you have to build mahout jar files first! they created in a target folder in each of the mahout main folder such as math,examples and ... then after extract zip file run this command to build jar files
sudo mvn -DskipTests install -e
after that you can run your example :)
