Kotlin Tooling and IDE Support

When you embark on a journey with Kotlin, having the right tools can make all the difference in enhancing productivity and streamlining the development process. In this article, we'll delve into the best Integrated Development Environments (IDEs) and tools available for Kotlin development, including setup instructions and useful extensions that can elevate your coding experience.

1. IntelliJ IDEA

Overview: One of the most renowned IDEs for Kotlin development is IntelliJ IDEA, developed by JetBrains, the same company behind the Kotlin language. This powerful IDE offers robust support for Kotlin out of the box.

Setup

  • Download and Install: Visit the IntelliJ IDEA website and select the Community version (free) or Ultimate version (paid) that suits your needs.
  • Create a Kotlin Project: Once installed, you can create a new project by selecting "New Project," choosing "Kotlin," and then following the prompts to set up your project structure.
  • Kotlin Plugin: While IntelliJ IDEA comes with Kotlin support pre-installed, you can check for updates through Preferences > Plugins > Marketplace to stay updated.
  • Kotlin Extensions for Android: If you are developing Android applications, make sure to install Android Studio, which is based on IntelliJ and comes with all necessary tools for Android development.

2. Android Studio

Overview: Specifically crafted for Android development, Android Studio offers a rich suite of tools for Kotlin developers. It includes features tailored to easily design, develop, and test Android apps.

Setup

  • Download and Install: Grab the Android Studio from the Android Developer portal.
  • Create a New Project: Open Android Studio and select "Start a new Android Studio project," picking Kotlin as your main programming language.
  • Kotlin Android Extensions: Ease your Android development with Kotlin Android Extensions, which provide a way to tap into view binding without boilerplate code.
  • Dagger Hilt: For dependency injection, Dagger Hilt integrates well with Kotlin, allowing for a concise and type-safe way to declare your dependencies.

3. Eclipse

Overview: Although IntelliJ IDEA and Android Studio are more popular among Kotlin developers, Eclipse can still be utilized for Kotlin development, particularly for those who prefer its environment or have existing projects in Eclipse.

Setup

  • Download and Install: Head to the Eclipse Downloads page to get the Eclipse IDE for Java Developers.
  • Kotlin Plugin Installation: To enable Kotlin support, install the Kotlin plugin from the "Eclipse Marketplace" within the IDE by searching for Kotlin.
  • Kotlin for Eclipse: This plugin enhances the IDE's functionality to support Kotlin development, providing features like syntax highlighting and code completion.
  • Maven and Gradle Integration: Using these build automation tools with Eclipse can simplify dependency management for your Kotlin projects.

4. Visual Studio Code

Overview: Visual Studio Code (VS Code) is a lightweight yet versatile code editor that can be tailored for Kotlin development with the help of extensions.

Setup

  • Download and Install: Get VS Code from Visual Studio Code's official page.
  • Kotlin Setup: Install the Kotlin extension from the Marketplace within VS Code by searching for "Kotlin".
  • Code Runner: This extension allows you to run Kotlin code snippets directly from the editor, making coding and testing quick and efficient.
  • Kotlin Language Support: A dedicated extension providing features like syntax highlighting, auto-completion, and linting.

5. Command-Line Tools

Overview: While IDEs are fantastic, some developers prefer command-line tools for their simplicity and flexibility. Kotlin offers CLI tools that facilitate building and running applications without needing extensive IDE support.

Setup

  • Install Kotlin Command-Line Compiler: Download the latest version from the Kotlin Releases page. Grab the command-line tools, unzip them, and include the bin directory in your system's PATH variable.
  • Building and Running Kotlin Code: You can compile Kotlin files using the command: 
    kotlinc YourFile.kt -include-runtime -d YourFile.jar
    Followed by execution: 
    java -jar YourFile.jar
  • Gradle: A powerful build automation tool that simplifies managing your Kotlin project. It allows for easily integrating libraries, defining project dependencies, and automating tasks.
  • Kotlin DSL: Tailor your Gradle build scripts using Kotlin DSL, making your build code type-safe and more expressive.

6. Build and Dependency Management Tools

Gradle

Overview: Gradle is an essential tool when it comes to building, testing, and managing dependencies in Kotlin projects.

Setup

  • Kotlin Gradle Plugin: To set up Gradle for Kotlin, include the Kotlin plugin in your build.gradle file: 
    plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.6.0'
}
  • Use Kotlin DSL for the build.gradle.kts format to write build scripts, taking advantage of Kotlin’s type-safety and IDE features.
  • Define dependencies using Gradle in a clean and understandable manner, which makes your project more maintainable.

Maven

Overview: Maven is another widely used build automation tool, providing a convention-over-configuration approach to project management.

Setup

  • Kotlin Maven Plugin: You can integrate Kotlin into your Maven builds by adding the Kotlin plugin to your pom.xml: 
    <build>
    <plugins>
        <plugin>
            <groupId>org.jetbrains.kotlin</groupId>
            <artifactId>kotlin-maven-plugin</artifactId>
            <version>${kotlin.version}</version>
        </plugin>
    </plugins>
</build>
  • Define your dependencies in Maven in a structured and clear way. Utilize the power of the Maven Central Repository for adding libraries easily.

Conclusion

Selecting the right tooling and IDE support is crucial for efficient Kotlin development. Whether you prefer the comprehensive features of IntelliJ IDEA and Android Studio, the flexibility of Visual Studio Code, or the simplicity of command-line tools, there’s a suitable option for everyone. Always enhance your development environment with the recommended plugins and extensions to make your Kotlin programming experience more enjoyable and productive. Happy coding!
