Software Development Kits (SDKs) are crucial tools for developers, aiding in the creation, debugging, and maintenance of software. However, managing multiple versions of SDKs can be a challenging task. Fortunately, this is where SDKMAN steps in. A version manager for Java and other JVM-related SDKs and tools, SDKMAN simplifies the process of installing, switching, and removing different versions of SDKs, making it an indispensable tool for developers.

Step 1: Updating Your System

Firstly, ensure that your Fedora system is up-to-date. You can do this by running the following command in the terminal:

sudo dnf clean all
sudo dnf update

Step 2: Installing SDKMAN

To install SDKMAN, open a terminal and execute the following command:

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

Follow the instructions on the screen to complete the installation. Afterward, open a new terminal or run the following command in the same shell:

source "$HOME/.sdkman/bin/sdkman-init.sh"

Finally, confirm whether the installation was successful by running:

sdk version

You should see the output containing the latest script and native versions.

Step 3: Using SDKMAN to Manage SDKs

With SDKMAN installed, you can now use it to manage your SDKs. Here’s how you can install, switch, and remove SDKs using SDKMAN.

To install an SDK, use the following command, replacing ‘sdk-name’ and ‘version’ with the name and version of the SDK you wish to install:

sdk install sdk-name version

To switch between different versions of an SDK, use the following command:

sdk use sdk-name version

To remove an SDK, use the following command:

sdk uninstall sdk-name version

Step 4: Troubleshooting Common Issues

While using SDKMAN, you might encounter some common issues. Here are a few troubleshooting tips:

• If SDKMAN commands are not working, ensure that SDKMAN is correctly installed by checking its version as described in the installation section.
• If you’re unable to install an SDK, check your internet connection and ensure that the SDK version you’re trying to install is available.
• If you’re having trouble switching between SDK versions, ensure that the versions you’re trying to switch between are installed.
