Scala and sbt Dockerfile

Scala, sbt and git container.

Useful for building in environments like CircleCI v2.

Base Docker Image

openjdk:8-jre-alpine

Installation

Install Docker
Pull automated build from public Docker Hub Registry:
See tags for built specific versions (not the latest ones)

docker pull codestar/circleci-scala-sbt-git

Alternatively, you can build an image from Dockerfile:

docker build -t circleci-scala-sbt-git github.com/codestar/circleci-scala-sbt-git

Or with specific versions:

docker build \
  -t circleci-scala-sbt-git \
  --build-arg SCALA_VERSION=2.12.3 \
  --build-arg SBT_VERSION=0.13.15 \
  github.com/code-star/circleci-scala-sbt-git

Usage

docker run -it --rm spikerlabs/scala-sbt /bin/bash

Example .circleci/config.yml:

version: 2
jobs:
  build:
    working_directory: ~/my-project
    docker:
      - image: codestar/circleci-scala-sbt-git:scala-2.12.2-sbt-0.13.15
    steps:
      - checkout

      - restore_cache:
          keys:
            - my-project-{{ checksum "project/build.sbt" }}-{{ checksum "build.sbt" }}
            - my-project

      - run:
          # TODO: For some reason circleci gets stuck in the shell if we don't add exit to sbt
          command:
            sbt compile test:compile exit

      - save_cache:
          key: my-project-{{ checksum "project/build.sbt" }}-{{ checksum "build.sbt" }}
          paths:
            - target/resolution-cache
            - target/streams
            - project/target/resolution-cache
            - project/target/streams
            - ~/.sbt
            - ~/.iv2/cache
            - ~/.m2
      - save_cache:
          # Changing this to a different key is the only way to remove old dependencies from the cache and/or generate a more up-to-date cache
          key: my-project
          paths:
            - ~/.sbt
            - ~/.iv2/cache
            - ~/.m2

      - run:
          command:
            sbt test exit

      - store_test_results:
          path: target/test-reports
