Kotlin Toolchain

JetBrains' unified CLI for Kotlin (JVM, Android, iOS, multiplatform) and Java projects, in Alpha. Configuration is declarative YAML instead of Gradle build scripts.

Installation

Prefer the project's checked-in wrapper: ./kotlin build needs nothing installed — the wrapper downloads the CLI itself. Install a global CLI only when there is no wrapper (e.g. before kotlin init):

sdk install kotlintoolchain      # SDKMAN (macOS / Linux / WSL)

The kotlin command then auto-provisions its JDK on first use. Other install options (installer scripts, IntelliJ IDEA plugin) live at https://kotlin-toolchain.org/.
