  url = null; # Optional - The git url, if empty it will be set to src.gitRepoUrl
  tagPrefix = "v"; # Optional - strip this prefix from a tag name
  hardcodeZeroVersion = false; # Optional - Use a made-up version "0" instead of latest tag. Use when the project's tagging system is incompatible with what we expect from versions
  tagFormat = "*"; # Optional - A `git describe --tags --match '<format>'` pattern that tags must match to be considered
