Smart code completion, linting, debugging, formatting and more for Kotlin in VSCode using the Kotlin language server and the Kotlin debug adapter.

To use, make sure that JDK 11+ is installed and open a Kotlin file inside a Gradle or Maven project. Support for Kotlin source files with a standalone compiler (kotlinc) is experimental. The language server will then automatically launch in the background.
