Re: [Nix-dev] Project environment setup

Looks like gradle25 package doesn't follow nixpkgs conventions here. It has no `.override` attribute, which, as I remember, is added by `callPackage` function. I think this is a bug, but there is a workaround: ``` # shell.nix { pkgs ? import {} }: let mygradle = (pkgs.gradleGen.override {

Re: [Nix-dev] Project environment setup

Ok I figured it out, sorry for the public conversation with myself but I hope that it can help other new Nix users. The use case is: you have some private nix expressions and would like to configure a project environment that includes those as well as some modified packages provided by

Re: [Nix-dev] Project environment setup

For example, the shell.nix I wrote below doesn't make a gradle available with openjdk8, and also takes 2m20s to load (!) when I run `nix-shell`: # shell.nix # nix-shell prints 'warning: dumping very large path (> 256 MiB); this may run out of memory' { pkgs ? import {} }: let mygradle =

[Nix-dev] Project environment setup

I've been reading the docs and blog posts but I'm still unsure on the proper way to configure a local shell.nix with my required modified packages. Specifically, I need gradle built with jdk 8, something like pkgs.gradle25.override { jdk = pkgs.openjdk8; } and I also have some local nix
