SDKMAN

SDKMAN! is a tool for managing parallel versions of multiple software development kits on most Unix-based systems. It provides a convenient command line interface (CLI) and API for installing, switching, removing and listing candidates.

Installation

Open a new terminal and enter:

 curl -s "https://get.sdkman.io" | bash

Follow the instructions on-screen to complete installation. Next, open a new terminal or enter:

Lastly, run the following code snippet to ensure that installation succeeded:

sdk version

If all went well, the version should be displayed. Something like:

Usage

Installing an SDK

Install the latest stable version of your SDK of choice (say, Java JDK) by running the following command:

sdk install java

You will see something like the following output:

Downloading: java 8u111

Now you will be prompted if you want this version to be set as default.

Do you want java 8u111 to be set as default? (Y/n):
Answering yes (or hitting enter) will ensure that all subsequent shells opened will have this version of the SDK in use by default.
