Upgrading Maven on Mac

To upgrade to the latest version (if you have one already installed but need to update the version) do the following:

1. brew update
2. brew unlink maven
3. brew install maven

if you then execute the mvn --version command you should see that your version of maven has been upgraded.

EDIT:
If you have an issue with the update (command 1) that goes along the lines of
error: The following untracked working tree files would be overwritten by merge: Library/Formula/...
try this answer from another issue

You created a symbolic link from your Downloads directory with a directory that may not exist anymore (or with an incorrect path). The directory /usr/bin/mvn obviously exists but the link is incorrect to the target which leads to the "No such file or directory" error when typing mvm --version.

Go through the tutorial again (which seems ok) but if you fail you could always try using Homebrew with the following commands :

brew update
brew install maven

if you installed maven in your mac, i use the next command...

>brew upgrade maven
