Reproducibility Check for Apache Maven master HEADs

reproducible-central gives a summary of artifacts in Central Repository that are reproducible, eventually partially.

This is great to spread the word once reproducibility work has been done for a public release, but when reproducibility work has not yet been done, it's sad to discover the issue after having done a release with the whole legal process.

For the many Apache Maven sub-projects, we need to check reproducibility of latest SNAPSHOT/master HEAD to identify as much as possible issues before releasing.

Reproducibility Results

Apache Maven consists in 88 sub-projects:

• Latest release: on 85 releases, reproducibility status is 41 ✔️ + 44 ⚠️ = 48% ✔️

• master HEAD SNAPSHOT: on 88 SNAPSHOTs, reproducibility status is 85 ✔️ + 3 ⚠️ = 96% ✔️
