How can I load a json file in the dojo application build profile?

I have the following dojo build profile:

var profile = (function () {
    return {
        basePath: "./Scripts",
        releaseDir: "./bin",
        releaseName: "",
        action: "release",
        mini: true,
        layerOptimize: "closure",
        optimize: "closure",
        cssOptimize: "comments",
        localeList: false,
        packages: [
            {
                name: "dojo",
                location: "l:/dojo-debug/1.10.4/dojo"
            },
            {
                name: "dijit",
                location: "l:/dojo-debug/1.10.4/dijit"
            },
            {
                name: "dojox",
                location: "l:/dojo-debug/1.10.4/dojox"
            },
            ...
        ],
        layers: ...
    };
})();

Now, I need to read values from some json file, so I am looking for something like this:

var profile = (function () {
    var versions = SomeHowReadTheContentsOf("ThirdPartyJsLibRootMap.json");
    return {
        basePath: "./Scripts",
        releaseDir: "./bin",
        releaseName: "",
        action: "release",
        mini: true,
        layerOptimize: "closure",
        optimize: "closure",
        cssOptimize: "comments",
        localeList: false,
        packages: [
            {
                name: "dojo",
                location: "l:/dojo-debug/" + versions["dojo-debug"] + "/dojo"
            },
            {
                name: "dijit",
                location: "l:/dojo-debug/" + versions["dojo-debug"] + "/dijit"
            },
            {
                name: "dojox",
                location: "l:/dojo-debug/" + versions["dojo-debug"] + "/dojox"
            }
            ...
        ],
        layers: ...
    };
})();

For the life of me I am failing to find the way to do it.

Any ideas?

EDIT

My command line is: node L:\dojo-debug\1.10.4\dojo\dojo.js load=build --profile .\package.profile.js

EDIT2

I have added a console log of all the properties of require, below is the result:

has = undefined
isXdUrl = undefined
initSyncLoader = undefined
eval = undefined
signal = undefined
on = undefined
map = undefined
rawConfig = undefined
legacyMode = undefined
async = undefined
waitms = undefined
baseUrl = undefined
idle = undefined
toAbsMid = undefined
toUrl = undefined
log = undefined
trace = undefined
injectUrl = undefined
getText = undefined
nodeRequire = undefined
uid = undefined
cache = undefined
packs = undefined
paths = undefined
aliases = undefined
modules = undefined
execQ = undefined
defQ = undefined
waiting = undefined
mapProgs = undefined
pathsMapProg = undefined
listenerQueues = undefined
computeMapProg = undefined
computeAliases = undefined
runMapProg = undefined
compactPath = undefined
getModuleInfo = undefined
boot = undefined
scopeify = undefined

So nodeRequire is there, but its value is undefined. Something is wrong.

If you are running the Dojo builder with NodeJS, you have access to its require via require.nodeRequire. Within a build profile file, you also have access to a variable called selfPath which is the absolute directory name of the profile file you have passed to the builder (it's similar to __dirname in a node module). Putting these two things together and assuming ThirdPartyJsLibRootMap.json is a sibling of your build profile:

var profile = (function () {
    var req = require.nodeRequire;
    var path = req('path');
    var versions = req(path.join(selfPath, 'ThirdPartyJsLibRootMap.json'));
    return {
        ...
    };
})();
