Documentation

Details

The following sbt plugins are used

• Git sbt-git

  Allows us to retrieve information about the commit such as the sha or the branch which is used to enhance the BuildInfo object

• BuildInfo buildinfo

  configured to generate a BuildInfo object on compile with

  • name
  • version
  • scalaVersion
  • sbtVersion
  • git.gitCurrentBranch
  • git.gitHeadCommit

  This information will be used to enhance the detailed health endpoint

• GitFlow sbt-git-flow

  The gitflow plugin extends the release plugin and as such maintains the versioning in the ./version.sbt file see sbt-release for more release options the sbt-assembly plugin is used to generate the fat jar in this pipeline see (git-flow-cheatsheet)[http://danielkummer.github.io/git-flow-cheatsheet/)

• Docker sbt-docker

  docker image naming convention is configured based on the fact that with gitflow we have two primary branches, master and develop It looks for an environment variable ${BRANCH_NAME}. If missing, its assumed that the docker image is being built for local testing

  Naming convention used:

  • no BRANCH_NAME -> organization/name:latest
  • develop -> registry/name:version-sha
  • master -> registry/name:version

  registry is the remote registry where the image is to be pushed version is develop will be Major.Minor.Patch-Snapshot

• Dependency Graph sbt-dependency-graph

  To generate dependency graph

• Format scalafmt-github

  see scalafmt for details

• Style scalastyle

  see scalastyle-github for details

• s3 Resolver fm-sbt-s3-resolver s3 will be used to host the snapshot and release jars
