# `++ 2.13.0 compile` has a different semantic than `;++2.13.0;compile`
# Strict aggregation applies ONLY to former,
#   and ONLY if crossScalaVersions := Nil is set in root project and ALL nested aggregates
# see https://github.com/sbt/sbt/issues/3698#issuecomment-475955454
# and https://github.com/sbt/sbt/pull/3995/files
# TL;DR strict aggregation in sbt is broken; this is a workaround
