SDKMAN is a command-line tool for managing parallel versions of multiple software development kits on Unix-based systems.
The tool solves the problem of juggling multiple SDK versions across a single machine. It provides a centralized interface for installing, switching between, removing, and listing different versions of development kits. Rather than manually managing PATH variables or maintaining separate installation directories, developers can use simple commands to activate the specific SDK version needed for each project.
SDKMAN suits developers who work across multiple projects with different SDK requirements, or those who need to test code against several versions of a language or framework. It works on any Unix-based system and handles the complexity of parallel version management transparently. The tool is particularly valuable for teams standardizing on specific SDK versions, since it can enforce consistent environments across developers.
The project is in a transition phase. The README states that all commands are being rewritten in Rust under a separate project, with this repository accepting only bug fixes to supporting code. No further enhancements will be accepted for the commands in this project, and they will be phased out over time. The project will eventually serve as a lightweight wrapper or launcher for the replacement Rust-based commands. The existing codebase uses Cucumber for behavior-driven testing, with tests runnable via Gradle, and requires a JDK for development work.
