The Secret to Developer Productivity: Discover SDKMAN

Introduction

• SDKMAN is a command-line tool for managing software development kits (SDKs).
• It simplifies the process of installing, managing, and switching between different SDK versions.
• It supports popular SDKs like Java, Maven, Gradle, Groovy, Scala, Kotlin, and more.
  Tip

  Personally I use for maven gradle and Java (JDK)
  

• SDKMAN provides a centralized repository of SDKs with various versions.
• It automates the installation and configuration of SDKs, saving developers time and effort.
• Developers can easily list available SDKs, install specific versions, and switch between them seamlessly.

Getting Started with SDKMAN

Installing SDKMAN on your system:

• Open your terminal or command prompt. for windows run from gitbash
• Run the following command to download and install SDKMAN:

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

Setting up SDKMAN environment variables:

• After the installation completes, run the following command to initialize SDKMAN:

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

Verifying the installation:

• To verify that SDKMAN is installed correctly, run the following command:

  1	sdk version

• It should display the version of SDKMAN installed.

Managing SDKs with SDKMAN

To effectively manage SDKs with SDKMAN, follow these steps:

Listing available SDKs and versions:

• To view the available SDKs and their versions, use the following command:

  1	sdk list <sdk>

• Example for Java JDK:

  1	sdk list java

  This command will display a list of available Java JDK versions.

Installing SDKs using SDKMAN:

• To install a specific SDK version, use the following command:

  1	sdk install <sdk> <version>

• Example for Java JDK:

  1	sdk install java 17.0.5-zulu

  This command will install Java JDK version 17.0.5-zulu.

Switching between different SDK versions:

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

  1	sdk use <sdk> <version>

• Example for Java JDK: suppose if you installed already sdk install java 11.0.17-zulu

  1	sdk use java 11.0.17-zulu

  This command will switch Java JDK version to 11.0.17-zulu.

Setting a default SDK version:

SDKMAN simplifies setting a default SDK version for each candidate, applying it automatically when you start a new session or open a terminal. Use the “default” command to set it effortlessly.

• Setting a default SDK version:

  1	sdk default <sdk> <version>

• Example for setting the default Java JDK version:

  1	sdk default java 17.0.5-zulu

  This command will set java jdk version 17.0.5-zulu as default.

Checking the current default SDK version:

• To check the current default version for an SDK candidate, use the following command:

  1	sdk default <sdk>

• Example for checking the default Java JDK version:

  1	sdk default java

  This command will display the currently set default version of Java JDK.

Removing SDKs with ease:

• To remove an installed SDK, use the following command:

  1	sdk uninstall <sdk> <version>

• Example for Java JDK :

  1 2	sdk uninstall java 11.0.17-zulu

  This command will uninstall Java JDK version 11.0.17-zulu.
