Deterministic/reproducible builds

(Issue migrated from Gitlab: Internal link)

A reproducible build process ensures that given source code will always compile byte-by-byte to the same output file. (in our case: JAR file)

This allows trivial auditing of releases by third parties, since the compilation can simply be repeated and a byte-by-byte comparison performed.

Maven supports reproducible builds, and I would like to introduce them into PDFOver.
