In their own words
Jabba
Jabba is a free Java version manager written in Go for installing and switching among JDK versions on macOS, Linux and Windows. Its JDK index, powered by DiscoAPI, lists versions for the user's operating system and architecture. The README names distributions including Oracle, Adopt OpenJDK, Zulu, IBM SDK, GraalVM, OpenJDK, Liberica and Amazon Corretto. Users can list remote JDKs, filter versions with semantic version ranges, install versions and switch among those installed. A `.jabbarc` file can specify a project's JDK, while a default alias can select the version used in new terminals. Jabba can link to a system JDK and coexist with an existing Java installation. The README documents shell integration for bash, zsh and fish, plus installation through Homebrew, shell scripts, PowerShell, Scoop or Docker. Custom JDK downloads are also supported. Jabba does not switch Java globally on its own; the README gives manual platform-specific snippets instead. The repository describes Jabba as a community fork that is a work in progress and warns that some README instructions may be outdated. It is licensed under Apache-2.0.
