Maven doesn’t ship by default anymore on Mavericks, which is annoying but lucky homebrew makes it easy to get it installed.
Just follow these two steps to install homebrew (if you haven’t already got it) and then install the maven brew…
Then sit back and enjoy some coffee.
#install homebrew if you don't have it already
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go/install)"
#install maven
brew install maven
