setup-everything-scala GitHub Action

A GitHub Action to prepare the environment for Scala & Scala.JS dev and testing.

Use this:

    - name: Setup Scala
      uses: japgolly/setup-everything-scala@v3.1

To replace (a subset of) this:

    - name: Setup Java and Scala
      uses: coursier/setup-action@v1.2.0-M2

    - name: Setup Node
      uses: actions/setup-node@v2

    - name: Setup Scala.JS
      uses: japgolly/setup-scalajs@v1

    - name: Setup Scala Utils
      uses: japgolly/setup-scala-util@v2.0

    - name: Cache sbt
      uses: coursier/cache-action@v6.3

Dynamic Scala Versions

If you have your Scala versions stored as vals or defs in your sbt field, then you can use sbt++field to set the Scala version dynamically. Example:

build.sbt:

  val scala211 = "2.11.10"
  val scala212 = "2.12.8"
  val scala213 = "2.13.6"
  val scala3   = "3.0.2"

.github/workflows/ci.yaml:

name: CI
on:
  pull_request:
  push:
jobs:
  ci:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        scala:
          - scala211
          - scala212
          - scala213
          - scala3

    steps:
      - name: Git checkout
        uses: actions/checkout@v2

      - name: Setup Scala
        uses: japgolly/setup-everything-scala@v3.1

      - name: Build and test
        shell: bash
        run: sbt++field ${{ matrix.scala }} test
