 Benedikt Ritter (britter) | Does anybody have an opinion on https://github.com/NixOS/nixpkgs/pull/449037? | 19:32:25 |
| Benedikt Ritter (britter) | And does anybody have a build node to run nixpkgs-review for this PR? Changing gradle always requires rebuilding a ton of stuff and I don't want to do that on my laptop. | 19:32:58 |

| Pol | Heya all, I got a question regarding Gradle. I'm building a container at work containing Gradle with jdk21_headless. I noticed that that size of the container is 1.9GB. When I checkout the size of the container on Docker Hum, it's around 400MB. Do you know the reason why it is so fat when the container is built with Nix? | 14:03:06 |

| Pol | I notice that the GTK libs are included in the closure, I don't really know if this is really needed. | 16:28:41 |

 raboof | so it seems the gradle-setup-hook still depends on the 'regular' jdk21 instead of on the headless one, apparently for keytool | 01:04:29 |
| raboof | adding .unwrapped to the expression drops the setup hook - not sure if that makes sense here though | 01:09:42 |
| Pol | I found this yesterday late evening thanks to nix-tree indeed. I was looking for replacing it with the java version, I'm still looking... but got buried with work lately, so it might take time. | 08:28:50 |

| Pol | This is already a tremendous improvements, but I guess there's room for improvements. | 08:56:01 |
