Hi! Team

I managed to sort out my issue.

I did the following
1. I had to update my homebrew
2. Updated ruby
3. Installed the ruby sass gems
3. Installed compass

brew update
brew install rbenv ruby-build
brew upgrade ruby
rvm install ruby-2.4.0
gem install sass
gem install compass

After the changes I was good to go.

I don't remember making a meaningful change on the pom file. But i changed it +-30 times.
I have included it just incase there is something i missed out.

I think you can remove maven sass plugin in the your pom.xml and try the following command on commandline;
sass -w src/main/webapp/resources/sass/layout.scss src/main/webapp/resources/omega-layout/css/layout.css --sourcemap=none

Please see; http://www.primefaces.org/omega/docs.xhtml
