I checked out a clean trunk and managed to get as far as step 6 without problems. 6 failed trying to pull the collections-codegen plugin 0.4-SNAPSHOT from a repo. I'm not sure why the reactor is not picking it up. Nevertheless, I was able to get past this by running a separate mvn clean install to push the plugin to my local repo.
When all is said and done, I get a bunch of errors from mahout-collections complaining about the @Overrides. Switching compliance to 1.6 of course eliminates these. The .checkstyle, .pmd and .ruleset files under each project cause svn to show changes. We should set svn:ignore on these -- or should they be checked in? Without getting too specific it strikes me that some of the stuff that PMD is complaning about should be downgraded from 'Error high' or 'Error' to some level of warning. For example it appears that all of the modules have errors of some level based on the existing (default?) settings. FWIW, here's my environment: mvn --version Apache Maven 2.2.1 (r801777; 2009-08-06 15:16:01-0400) Java version: 1.6.0_16 Java home: /u01/opt/jdk1.6.0_16/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux" version: "2.6.28-18-server" arch: "i386" Family: "unix" On Mon, Mar 22, 2010 at 9:35 AM, Benson Margulies <bimargul...@gmail.com> wrote: > I need a brave eclipse user to try out the following, and then I have > some questions for others. > > 1) Remove all .project and .classpath files from your tree. > 2) cd to 'eclipse'. > 3) Pick a new pathname for an eclipse workspace (call it WORKSPACE) in > the following. > 4) mvn -Psetup-eclipse-workspace -Declipse.workspace.dir=WORKSPACE > > This much will create WORKSPACE, copy some files into it, and set some > global options. > > 5) cd ..
