.drone.yml

# Common parts

# FYI: There's no merging of arrays in YAML. At least not in the Go library
# Drone uses to parse YAML. So if you mix in &sbtenv and want to add
# additional volumes, as in docker-build step, you need to specify all volumes.

# See https://bors.tech/documentation/getting-started/ for why we have trying and staging here:
__branches: &branches
  # Merges to `dev` are only ever done by bors, using a fast-forward merge, if the `staging` build passes.
  # This means everything that lands in dev has already been tested in CI. Hence, the `dev` build is redundant.
  # - dev
  - master
  - release-*
  - testing*
  - trying
  - staging
