Hi!

While conducting a research in the spirit of the "reproducible builds" [1], we have noticed that the package sweethome3d could not be built reproducibly, in that timestamp will be embedded when jar file(s) are generated (see attached diff.json). According to the documentation [2], applying strip-nondeterminism will strip non-deterministic information such as timestamps and filesystem ordering. The attached patch does exactly this. Once applied, the package can be built reproducibly.


Additional info:
* sweethome3d 6.5-1

Steps to reproduce:
The unreproducible build result could be detected with reprotest [3].
