In the changing world of software development, handling many Software Development Kits (SDKs) can be tough for you. You might like a tools that helps you handle this easily. SDKMAN! helps by making it easier to manage different versions of SDKs on most Unix-based systems. This guide will show you how to install and use SDKMAN on Ubuntu for easy SDK management.
What is SDKMAN?
SDKMAN! is a tool that helps you install, manage, and switch between different versions of software development kits like Java, Groovy, Scala, Kotlin, and more. It makes it easier for developers to keep their development environments organized, especially when working on many projects or testing apps with different SDK versions.
Steps to Install SDKMAN on Ubuntu
Step 1: Open a Terminal
Access your terminal by pressing Ctrl + Alt + T on your keyboard or by searching for ‘Terminal’ in your system’s application launcher.
Step 2: Download and Install SDKMAN
Enter the following command in your terminal to download and execute the SDKMAN installation script:
curl -s "https://get.sdkman.io" | bash
This command fetches the installation script using curl and pipes it to bash for execution. Follow any on-screen prompts to complete the installation.
Step 3: Initialize SDKMAN
To start using SDKMAN, you need to initialize it in your current shell session. Run:
source "$HOME/.sdkman/bin/sdkman-init.sh"
This command ensures that the SDKMAN environment is loaded into your shell.
Using SDKMAN on Ubuntu
With SDKMAN installed, you can now easily manage your development kits. Here are some common commands to get you started:
- Listing Available SDKs
To see a list of all available SDKs, use:
sdk list - Installing an SDK
To install a specific version of an SDK (for example, Java), run:
sdk install java 11.0.2-openReplace 11.0.2-open with the version you wish to install.
- Switching Between SDK Versions
Switching between installed versions of an SDK is straightforward:
sdk use java 11.0.2-openAgain, replace 11.0.2-open with the version you want to switch to.
- Uninstalling an SDK
To remove an installed SDK version from your system, execute:
sdk uninstall java 11.0.2-open - Updating SDKMAN
Keep SDKMAN and your SDKs up to date by running:
sdk updateFollowed by:
sdk upgradeThese commands will update the SDKMAN tool itself and then upgrade any SDKs you have installed to their latest versions.
Conclusion
SDKMAN! is a strong but easy tool for managing multiple software development kits on Ubuntu. It makes the process simple and boosts productivity. By following this guide, you’ll be ready to manage different SDK versions easily, letting you focus more on coding and less on setting up your environment. Happy coding!
