[Java] Provide reproducible builds

[jbonofre]

Describe the enhancement requested

Currently, our provided artifacts are not reproducible, meaning that two builds provide different artifacts.

Reproducible builds, also known as deterministic compilation, is a process of compiling software which ensures the resulting binary code can be reproduced. Source code compiled using deterministic compilation will always output the same binary.

In order to have reproducible builds, we need to add a property (with fixed compile output timestamp) and be sure we use the maven plugins version compliant with reproducible builds.
