## What it is
Jabba is a cross-platform Java Version Manager written in Go that lets developers install and switch between multiple JDK versions. This original repository is no longer maintained and development has moved to a community fork.

## Use cases
- install multiple jdk versions
- switch java versions per project
- manage java sdks on windows mac linux
- pin java version for ci
- download openjdk builds from the command line

## When to choose
- you need a simple cross-platform java version switcher and prefer the maintained fork
- you want jdk management without sdkman's bash dependency

## When to avoid
- you want active maintenance and bug fixes - use the Jabba-Team fork instead
- you need jvm ecosystem tooling beyond jdk switching

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: package-manager, cli, developer-tools
- domain: developer-tools, programming-languages
- platform: windows, cli, cross-platform
- tags: java, jdk-version-manager, version-switching, go, command-line, linux, macos
