## What it is
A Homebrew tap providing casks to install AdoptOpenJDK builds of OpenJDK (JDK and JRE, HotSpot and OpenJ9) on macOS. It is officially deprecated in favor of Homebrew's Temurin casks and receives no further updates.

## Use cases
- install openjdk on macos with homebrew
- install specific jdk version via brew
- install multiple java versions side by side on mac
- install openj9 jvm via homebrew
- switch between jdk versions on mac

## When to choose
- you are stuck on an old macOS setup already using this tap and cannot migrate yet

## When to avoid
- setting up Java on macOS today - use the temurin cask instead
- you need updated or supported OpenJDK builds
- you are on Linux or Windows

## Facets
- artifact type: plugin
- maturity: abandoned
- function: package-manager, developer-tools
- domain: developer-tools, cross-platform
- platform: cli
