## What it is
SDKMAN! is a command-line tool for managing parallel versions of multiple Software Development Kits (primarily JVM-related like Java, Kotlin, Groovy, Gradle, Maven) on Unix-based systems. It lets developers install, switch, list, and remove SDK versions from the terminal without manually managing downloads or PATH variables.

## Use cases
- install and switch between multiple Java versions
- manage parallel versions of JVM SDKs like Kotlin, Scala, and Groovy
- set per-project SDK versions automatically
- list and install build tools like Gradle, Maven, and SBT
- avoid manually editing PATH and HOME environment variables
- manage development toolchains on Linux, macOS, or WSL

## When to choose
- you work with JVM ecosystems and need multiple SDK versions side by side
- you want a lightweight, curl-installable manager that only needs bash, curl, zip, and unzip
- you need per-project or per-shell SDK version switching similar to RVM or rbenv
- you develop on Unix-based systems including macOS, Linux, or WSL

## When to avoid
- you need native Windows support outside WSL or Git Bash
- you want a general-purpose package manager for non-SDK system software
- you need new CLI features - development has moved to the Rust-based sdkman-cli-native successor
- you rely on Cygwin, which is no longer supported
