How to uninstall Maven on a Mac, and its local repository
Remove Maven with Homebrew or from its unpacked folder, and the ~/.m2 repository of downloaded libraries, which is usually larger than Maven.
How do I uninstall Maven on a Mac?
brew uninstall maven for Homebrew. Ours, version 3.9.11, was 10 MB. If you unpacked it by hand, remove that folder and the M2_HOME or PATH lines in ~/.zshrc.
What is the .m2 folder?
~/.m2/repository is Maven's local copy of every library any project downloaded. Ours was 44 MB; on a Mac that has built a few large projects it is often several gigabytes. ~/.m2/settings.xml holds your settings, including any repository passwords, so check it before deleting.
