Hi @leiqi96,

Can you try DOCKER_BUILDKIT=1 dapper cargo test?

The INCLUDE+ instruction comes from Dockerfile+ extension and using such extensions works only with Docker Buildkit enabled.

We probably need to somehow document to always enable DOCKER_BUILDKIT, for people who are not using the newest Docker versions.
