This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
Where exactly is your problem? Eclipse? Mahout? The algorithm? Fetching the data? Why are the wikis and blogs that you checked not enough?
Anyhow, nothing that you mentioned has anything to do with "build tools".
