automate check for unreleased code #2
Description
current rebuild.sh is perfect to easily check officially released artifacts, against content available in Central repository
when the result is "it works, yay!", that's perfect, but when the result is "nice try, but you can do better", it's too late: the release is there
there is a recipe to build locally twice and check against each other: https://maven.apache.org/guides/mini/guide-reproducible-builds.html
automating this recipe would permit to test master HEAD of projects before doing a release
