 Toma | So, some of you might remember that I started working on making more java apps reproducible in https://github.com/NixOS/nixpkgs/issues/278518
and currently one of the roadblocks is that the hook that's used (canonicalize-jars-hook) is a little bit broken.
I had opened a PR which tidied it up a bit (https://github.com/NixOS/nixpkgs/pull/278322/files), but there were several weird issues and special cases that came up.
One of the issues was that unzipping and rezipping jars in jars (e.g. dependencies packaged by springboot) caused it to not work anymore. (Probably due to this method not preserving the original compression-type)
But I found that just using zip-traversal can mitigate this issue. Example: https://github.com/NixOS/nixpkgs/pull/283305/files
I was pretty happy with the solution other than it would require java to run if I wanted to package it standalone.
So inspired by this, I recently made a tool in rust, which could replace canonicalize-jar as it is today.

I was wondering if packaging this could be an acceptable solution. | 18:33:00 |

I was wondering if packaging this could be an acceptable solution. Wouldn't it be better to do it in Java to avoid mixing different programming languages? | 18:41:13 |

Wouldn't it be better to do it in Java to avoid mixing different programming languages? It could be better, but we couldn't hard-code the jdk version in the hook, as we wouldn't want to use two different jdk versions for building.
An option could be to just expect jdk to be in the build environment, another would be to always do canonicalize-jars-hook.override { inherit jdk; } or something similar | 18:45:33 |
