Unable to use same argument in different scopes

[MertCingoz]

Description

Dockerfile

ARG JDK_SOURCE=azul/zulu-openjdk
ARG JDK_VERSION=17
FROM ${JDK_SOURCE}:${JDK_VERSION} AS build

ARG JDK_VERSION
RUN echo ${JDK_VERSION}

Dockerfile works fine when building with docker cli, but docker-maven-plugin seems to be removing outer scope.

Given Docker name 'azul/zulu-openjdk::latest' is invalid:
   * image part 'zulu-openjdk:' doesn't match allowed pattern '[a-z0-9]+(?:(?:(?:[._]|__|[-]*)[a-z0-9]+)+)?(?:(?:/[a-z0-9]+(?:(?:(?:[._]|__|[-]*)[a-z0-9]+)+)?)+)?'

My current workaround is creating dummy copy of same argument and using copy argument in inner scope.

ARG JDK_SOURCE=azul/zulu-openjdk
ARG JDK_VERSION=17
# Workaround for docker-maven-plugin to re-use arguments
ARG JDK_VERSION_COPY=${JDK_VERSION}
FROM ${JDK_SOURCE}:${JDK_VERSION} AS build

ARG JDK_VERSION_COPY
RUN echo ${JDK_VERSION_COPY}
