"authenticated" entry missing from some dependencies

[lverns]

I was trying to build the Spark Framework for NixOS, using this tool. Running mvn org.nixos.mvn2nix:mvn2nix-maven-plugin:mvn2nix in a checkout of the 2.5.4 branch of the Spark repo produced a project-info.json file that is almost 1 MB.

I then attempted to use the JSON file to with the following function definition:

{ stdenv, buildMaven }:

let
  autoGeneratedDerivation = buildMaven /home/spark/project-info.json;
in
autoGeneratedDerivation

This produced the following error:

error: attribute ‘authenticated’ missing, at /nix/store/lwmgp564z0bl06svlnw21gg3qy8kw3vb-nixos-16.09.1512.6b28bd0/nixos/pkgs/build-support/build-maven.nix:17:39

The structure of the JSON is not yet documented (as per #2), but here is what I'm seeing. The JSON file is a map with two keys project and dependencies. The value associated with dependencies is an array of maps, with each map specifying a dependency. e.g.

{
    "artifactId": "maven-bundle-plugin",
    "groupId": "org.apache.felix",
    "version": "2.5.3",
    "classifier": "",
    "extension": "pom",
    "dependencies": [ CONTENT_OMITTED   ],
    "authenticated": false,
    "url": "https://repo.maven.apache.org/maven2/org/apache/felix/maven-bundle-plugin/2.5.3/maven-bundle-plugin-2.5.3.pom",
    "sha1": "2ce17ed65ebde5afd0b48781f89f2c372f990c17",
    "relocations": [ ]
}

However, some (around 20?) of these maps look different:

{
    "artifactId": "apache",
    "groupId": "org.apache",
    "version": "9",
    "classifier": "",
    "extension": "pom",
    "dependencies": [ ]
}

Thus the buildMaven function crashes when it tries to inherit the authenticated attributed from the parsed JSON.

If tried producing the project-info.json with both Maven 3.3.9 and 3.2.5, and this issue was in both outputs (although the outputs were slightly different). I'm running NixOS 16.09.

Is this just an instance of #5? I don't really understand what that issue is about.

If any more details are needed, I will do my best to provide them.

I believe this is an instance of 5, yes
