Hi laverne, did you manage to figure it out? I think the usage would be to run https://github.com/NixOS/mvn2nix-maven-plugin on your project and then in your default.nix add something like: ``` { pkgs ? import <nixpkgs> {} , buildMaven ? pkgs.buildMaven }: buildMaven ./infofile ``` Where the `./infofile` is the file generated by mvn2nix (it should be a JSON file). As you can see not a lot of people are packaging java apps :) Cheers, z On Fri, 10 Feb 2017 at 05:47 laverne <[email protected]> wrote: Hi, I have a question about the function defined at https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/build-maven.nix I wanted to use it to build Spark Frame (http://sparkjava.com/), however, while the function is in all-packages, it isn't doesn't seem to be used anywhere else in nixpkgs. Is anyone here using the function in other projects that they would be willing to link to so that I could get a feel for how to use it? Thanks, Laverne No, I never did get it to work, but I hadn't tried the exact code that you recommend.
