That's strange. I got this error when I run mvn clean package docker:build:

[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.2.12:build (default) on project helioscanary: Exception caught: https URI must be provided to use certificates -> [Help 1]

I think your issue can be solved by changing tcp to https in <dockerHost>https://192.168.99.100:2376</dockerHost>. You could also remove that line and set an the environment variable DOCKER_HOST=tcp://<host>:2375.

Let me know if this works. If so, you can close the issue.

[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.2.12:build (default) on project helioscanary: Exception caught: https URI must be provided to use certificates -> [Help 1]

need to set; env variable

yangtaodeMacBook-Pro:micro-service-campaign yangtao$ docker-machine env dev
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/Users/yangtao/.docker/machine/machines/dev"
export DOCKER_MACHINE_NAME="dev"
# Run this command to configure your shell: 
# eval "$(docker-machine env dev)"

now i will change the "tcp://192.168.99.100:2376" to "https://192.168.99.100:2376" , will happend new error

@yangtao309 This means you are trying to pull something from a docker registry that requires authentication. See https://github.com/spotify/docker-maven-plugin#authenticating-with-private-registries. Closing for now as it seems these errors are caused by misconfiguration.
