      # This is needed because of differences in how Maven and Coursier download artifacts
      # Maven will only download the pom when the transitive dependency is not needed in the current projects compile classpath
      # whereas Coursier expects the artifact (jar) to be present in a Maven repository. When Coursier encounters a
      # artifact folder with a pom it considers the artifact to be available and will then crash when the jar is missing.
