The documentation on the wiki seems pretty outdated. But the transition isn’t 
really complicated. Most of the work is the manual work of converting the 
Eclipse project—here’s a basic guide for achieving that for an application 
project:

https://gist.github.com/hugith/e9a49e91fbcebe204e0feb4989f55631

Note that before you can actually do this, though, you’ll have to copy the 
following file to ~/.m2/settings.xml. It informs maven about the WOCommunity 
maven repositories where the WO specific stuff lives.

https://gist.github.com/hugith/e2887fad3baecdd493e0b9f5311fe0bf

After having done this with a few dozen projects, migrating a regular no-frills 
Fluffy Bunny project to maven takes me less than an hour these days (including 
upgrading the Jenkins build :). I sincerely recommend you give it a try. It’s a 
huge boon to productivity; dependency management alone will save you hours of 
headaches if you’re using any 3rd party software. And not having to manage 
framework installations is awesome.

Also, I currently don't have a life so I’m usually online to help if you run 
into issues ;).

Cheers,
