I'm trying to build rabbitmq-server in docker with the following dockerfile:

ARG RABBITMQDEVENV_VERSION

FROM rabbitmqdevenv/build-env-$RABBITMQDEVENV_VERSION

SHELL ["/bin/bash", "-c"]

WORKDIR /docker

# update certificates with proxy certificates
COPY . .
RUN chmod 644 certificates/* \
	&& cp -RT -v certificates/ /usr/local/share/ca-certificates/ \
	&& update-ca-certificates --verbose

ARG RABBITMQ_GIT_TAG
ENV RABBITMQ_SERVER_DIR=rabbitmq-server
# turn the detached message off
RUN git config --global advice.detachedHead false \
	&& git clone -c core.symlinks=true --depth 1 --branch $RABBITMQ_GIT_TAG https://github.com/rabbitmq/rabbitmq-server.git $RABBITMQ_SERVER_DIR

RUN cp -RT -v deps/ $RABBITMQ_SERVER_DIR/deps/

# ADDITIONAL_PLUGINS - to include new plugins (all, except mentioned in rabbitmq-components.mk, e.g. rabbitmq_shovel) to gmake 'fetch-deps'
# IGNORE_DEPS - to exclude updated plugins (mentioned in rabbitmq-components.mk, e.g. rabbitmq_shovel) from gmake 'deps'
RUN ADDITIONAL_PLUGINS=() \
	&& IGNORE_DEPS=() \
	&& for dir in deps/*/; do \
		dir_name=$(basename "$dir"); \
		if ! grep -qw "$dir_name" $RABBITMQ_SERVER_DIR/rabbitmq-components.mk; then \
			ADDITIONAL_PLUGINS+=("$dir_name"); \
		else \
			IGNORE_DEPS+=("$dir_name"); \
		fi; \
	done \
	&& echo "export ADDITIONAL_PLUGINS=\"${ADDITIONAL_PLUGINS[*]}\"" > ADDITIONAL_PLUGINS.env \
	&& cat ADDITIONAL_PLUGINS.env \
	&& echo "export IGNORE_DEPS=\"${IGNORE_DEPS[*]}\"" > IGNORE_DEPS.env \
	&& cat IGNORE_DEPS.env

ENV HEX_UNSAFE_HTTPS=true
RUN . ./ADDITIONAL_PLUGINS.env && gmake -C $RABBITMQ_SERVER_DIR fetch-deps
RUN . ./IGNORE_DEPS.env && gmake -C $RABBITMQ_SERVER_DIR deps

and I wanted to drop last RUN instruction (to run it in different container, in the environment w/o internet access), but at least rabbitmq_cli runs mix in deps target.

Shouldn't it be done in fetch-deps?
