Why SDKMAN? SDKMAN simplifies the process of installing, switching between, and managing multiple versions of on Unix-based systems.

Installation

  • Install SDKMAN if you don't have it already.
    • Open Terminal and run the following command.

    • Restart your terminal or run:
      source "$HOME/.sdkman/bin/sdkman-init.sh"
    • To verify the installation, run:
      sdk version
  • Install JDK using SDKMAN
    • Install the Java 17 JDK FX version (codename Zulu) by running:
      sdk install java 17.0.11.fx-zulu
    • This version should be automatically set as the default, but if it is not, set it as the default by running:
      sdk default java 17.0.11.fx-zulu

    java -version

If you encountered issues following the above instructions, you can also watch the video below for a more visual explanation (note that the JDK version it uses is not the one we want -- so, adapt accordingly).

Switching between Java versions

If you have multiple versions of Java installed, you can switch between them using SDKMAN.

  • To see the currently active Java version run,
    sdk current java
  • To switch to a different installed version, run the following command first.
    sdk use java
    Then press the Tab key to see the available versions installed on your computer. Keep pressing the same key until you select the desired version, and hit Enter.

  • If you don't have the desired version installed, you can install it by running the following command (as before):
    sdk install java <version>
  • To set a different version as the default, use the following command (as before):
    sdk default java <version>
