Subject Help building mahout
Date Thu, 27 Jan 2011 13:18:45 GMT

I'm trying to build mahout from svn and while trying to build the core I
get the following error. I have revision r1063437 checked out.

[ERROR] Failed to execute goal on project mahout-core: Could not resolve

( -> [Help 1]

Here's what I did,
Cd to math 

     1. mvn compile 
     2. mvn install 
     3. One of the tests failed so I did 
              * mvn -DskipTests install 
              * test that failed was testLogNormalize 
  * cd to ../core 

     1. mvn compile 
             1. Got the error above.
I tried to build math because when I tried to build core, I got an error
about not being able to obtaion mahout-math.jar:0.5-SNAPSHOT
