SDKMan
A command-line tool for managing parallel versions of multiple software development kits on Unix-based systems.
What is SDKMan?
SDKMAN! is a command-line tool for managing parallel versions of multiple Software Development Kits (SDKs) on Unix-based systems. It solves the problem of SDK version conflicts by allowing developers to install, switch, and remove different SDK versions easily. The tool supports various SDK candidates like Java, Scala, and Kotlin, providing a unified interface for SDK management.
Developers working on Unix-based systems (Linux, macOS) who need to manage multiple versions of SDKs for different projects, particularly those using JVM languages like Java, Scala, or Kotlin.
Developers choose SDKMAN! because it offers a simple, consistent CLI for SDK management, eliminating manual installation hassles and environment variable tweaking. Its ability to handle parallel SDK versions helps maintain project-specific dependencies without system-wide conflicts.

Use Cases
Best For
- Managing multiple Java versions for different projects
- Switching between Scala or Kotlin SDK versions quickly
- Installing and testing new SDK candidates without affecting existing setups
- Maintaining clean development environments on Unix systems
- Automating SDK setup in development or CI environments
- Reducing manual SDK installation and configuration overhead
Not Ideal For
- Windows-native development environments without WSL or Cygwin
- Projects requiring cross-platform SDK management across Windows, Linux, and macOS uniformly
- Teams needing active feature development or enhancements, as the CLI is in maintenance mode
Pros & Cons
Pros
Installation is a one-liner with 'curl -s https://get.sdkman.io | bash', as per the README, making setup quick and straightforward.
Allows installing and switching between multiple SDK versions like Java or Scala, reducing environment conflicts for different projects.
Supports various SDK candidates such as Java, Scala, and Kotlin through a unified CLI, streamlining management across languages.
Backed by sponsors and contributors with Discord support and documentation on sdkman.io, ensuring reliable resources for users.
Cons
Designed specifically for Unix-based systems like Linux and macOS, so it lacks native Windows support, limiting its usability in mixed environments.
The README states no enhancements are being accepted due to a rewrite in Rust, meaning this version is feature-frozen and only receives bug fixes.
Users may need to migrate to the new Rust-based CLI in the future, as this project will be phased out, potentially causing disruption.
