| fzakaria (Old) | Wait, is this JVM-Nix or just JVM ?
(I'm into both lol) | 23:09:42 |

 @grahamc:nixos.org | it is whatever you want to make it :) | 13:45:02 |

| fzakaria (Old) | I keep chipping away at JVM/Java but it's so entrenched.
Considering my experience in industry is how pervasive Java is | 15:02:52 |
| fzakaria (Old) | i'm surprised more upstream fixes or 👀 are not on Java in Nixpkgs | 15:03:04 |
| fzakaria (Old) | I'm slowly making progress.
Here's my JDK11 patch https://github.com/NixOS/nixpkgs/pull/127106 | 16:32:02 |

Here's my OpenJDK11 patch https://github.com/NixOS/nixpkgs/pull/127106 | 16:32:10 |
| @grahamc:nixos.org | this is really useful, I know of a few Java-heavy shops that want to use Nix | 18:03:42 |
| fzakaria (Old) | Nix & Java are challenging especially fixed output since Zip & Java's class files (IR) can contain non-reproducible artifacts (i.e. timestamps) | 18:37:47 |
| fzakaria (Old) | A good patch might be to also remove that so that by default they are reproducibe | 18:38:03 |

| Robert Hensing (roberth) | I'm surprised to learn we don't have a generators or formats for java properties | 09:47:36 |

| Robert Hensing (roberth) | I hope someone already has a decent implementation but grepping for .properties in Nixpkgs I didn't find a good one | 09:48:16 |
| fzakaria (Old) | oh cool. | 16:23:12 |
| fzakaria (Old) | ini is almost a superset of properties | 16:23:43 |
| fzakaria (Old) | JSON and TOML are builtins? | 16:25:34 |

| dschrempf | Hi! I am referring to the discussion on discourse about packaging a Maven project with mvn2nix. I am slowly moving forward. At the moment, I have the following problem: The Google Ortool Makefile builds two Maven packages in a row, the first being a prerequisite of the other. So essentially, I need to merge the dependencies of two project into a single lock file, so that both projects can be built using the same local Maven repository. Is there an easy way to do this? | 12:09:17 |
| dschrempf | FYI: https://discourse.nixos.org/t/updating-jugglinglab-packaging-a-maven-repository/13726 | 12:09:37 |
| dschrempf | For your reference, I merged it manually for now jq -s '.[0][] * .[1][]' mvn2nix-ortools-java-lock.json mvn2nix-ortools-linux-x86-64-lock.json > merged.json and then adding the dependency key by hand. | 12:40:23 |
