sbt docker:publishLocal logs build info as error

[joesan]

Expected behaviour

sbt docker:publishLocal builds the docker image and logs the status as info

Actual behaviour

sbt docker:publishLocal build the docker image successfully, but the logs are logged as error and that makes things confusing.

[hertg]

I have the same issue after installing docker-buildx on my machine.

My current workaround for this issue is to add the --quiet flag to the docker build options. This will prevent the diagnostic output from being printed at all.

dockerBuildOptions += "--quiet"
