Subject Problems building Mahout
Date Tue, 08 Feb 2011 11:01:35 GMT
Hello,

I'm a newbie to both Mahout and Maven. I'm trying to get Mahout work
for a recommender university project.

I'm running Ubuntu 10.04, java 1.6:
Apache Maven 2.2.1 (rdebian-1)
Java version: 1.6.0_22
Java home: /usr/lib/jvm/java-6-sun-1.6.0.22/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux" version: "2.6.32-26-generic" arch: "i386" Family: "unix"

I downloaded the 0.4 mahout release. When I run mvn clean install -e
in the directory I get the following error. This happens also on the
current trunk, even if I try it multiple times, deleting the ~/.m2/
directory. Am I doing something wrong?

Thanks a lot

Petr
