OpenJDK 64-Bit GraalVM CE 19.2.0.1 (build 25.222-b08-jvmci-19.2-b02, mixed mode )Ĭonsider the Kotlin version of âHello, World!â from Figure 1-1, reproduced here: fun main () īoth of these snippets use the Groovy DSL syntax for Gradle build files, which supports both single- and double-quoted strings. OpenJDK Runtime Environment (build 1.8.0_8u-src. For the current recipe, the free Community Edition was installed using the SDKMAN! tool: > sdk install java 19.2.0.1-grl You can install GraalVM from the downloads page. This recipe shows a simple example of how to use GraalVMâs native-image tool to create a native binary from Kotlin source code. One nice feature of GraalVM is that you can use it to create a native executable from your code. You can write in a JVM-based language like Java or Kotlin, and integrate with JavaScript, Ruby, Python, R, and more. GraalVM is a high-performance virtual machine that provides a cross-language runtime for running applications written in a variety of languages. A typical response to that command is shown here: > kotlin -version Regardless of how you install Kotlin, you can verify that it works and is in your path by using the simple command kotlin -version. This installs an LLVM backend for the Kotlin compiler, a runtime implementation, and a native code generation facility by using the LLVM toolchain. That is sufficient, but if you want to try it, there is an experimental installer called kotlin-native, which installs a native Windows compiler as well. This will install the scripts kotlin.bat, kotlinc.bat, kotlin-js.bat, and kotlin-jvm.bat and add them all to your path. Once Scoop is installed, the main bucket allows you to install the current version of Kotlin: > scoop install kotlin Simple installation instructions are found on the Scoop website. Scoop requires PowerShell 5 or later and. Scoop does for Windows what the other package managers do for non-Windows systems. Other package managers that support Kotlin include Homebrew, MacPorts, and Snapcraft. IntelliJ IDEA or Android Studio can use the downloaded versions, or they can maintain their own versions separately.
