Build of Dockerfile with multistage build fails on private registry

Description

We have private docker registry which requires authenication (we tried to pass the user and password via .m2/settings.xml, directly via CLI params and by logging in via docker, it’s all the same ). The build fails when Dockerfile contains multi-staged build (Dockerfile contains multiple FROM statements), specifically on the second FROM statement with Unable to build image [docker-develop.lnd.bz/sandbox/dmpmsbp:latest] : "Get https://docker.lnd.bz/v2/nginx/manifests/1.10: no basic auth credentials"

• If it’s a bug, how to reproduce : Sample pom.xml and Dockerfile attached. One would need private repo with authentication and docker images used in the Dockerfile not present on local system (so the download must occure). The first image is downloaded properly, the second one fails.

• Sample project : dmpmsbp.zip maven-output.log

Thanks, I just confirmed as well, that multistage with FROM statements referring to registry-images like in your example above works.

@xfh: oh, okay. I would close this and investigate #1264 then 😉
