This action downloads the Kotlin compiler and installs it to the path. It won't touch the installed JREs.

As of now, it only supports downloading Kotlin 1.4.0.

It allows you to use the kotlinc and the kotlin tool to compile source code and run scripts.

Usage example:

name: CI
on:
  push:
  workflow_dispatch:
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - uses: fwilhe2/setup-kotlin@main
    - run: kotlinc myProgram.kt -include-runtime -d /tmp/hello.jar; java -jar /tmp/hello.jar
    - run: kotlin myScript.main.kts

If you provide a string-argument script, the action will execute it via kotlin-main-kts script definition jar, see this example:

    - uses: fwilhe2/setup-kotlin@main
      with:
        script: |
            #!/usr/bin/env kotlin
            //more kotlin script code here
