mv: cannot stat 'project/sbt/bin/sbt-launch.jar': No such file or directory
Error: Unable to access jarfile project/sbt-launch-0.13.13.jar

Indeed, there is not such file in project/, but there is a project/sbt-launcher-packaging-0.13.13/bin/sbt-launch.jar. So I copy that file as project/sbt-launch-0.13.13.jar, and now it works.
