Documentation 'Using a multi-stage Docker build' with Gradle needs updating

[klemen-df]

Description

We are building a multistage docker according to this ('Sample Dockerfile for building with Gradle') guide here https://quarkus.io/guides/building-native-image#multistage-docker

There are some issues in this guide :

COPY --chown=quarkus:quarkus /code/gradle

What are we copying here?

FROM quay.io/quarkus/ubi-quarkus-native-image:21.3.1-java11 AS build

Should/can we update to java17?

USER quarkus

Original image 'ubi-quarkus-native-image' is already run as user 'quarkus', why duplicate?

RUN gradle -b /code/build.gradle buildNative

Gradle is not in PATH so we should do ./gradle

We are already in code folder (workdir) so we can omit the '/code/'

Parameter 'buildNative' is deprecated ('The 'buildNative' task has been deprecated in favor of 'build -Dquarkus.package.type=native''). When we run with the new command it has some problems with missing xargs package.

Implementation ideas
