Electron Forge packaging configuration not working - electron-forge

Question

I am trying to package my app with electron-forge package using the following configuration:
"config": {
"forge": {
"make_targets": {
"linux": [
"deb"
],
"win32": [
"squirrel"
]
},
"electronPackagerConfig": {
"asar": false,
"dir": "./src",
"platform": [
"linux",
"win32"
],
"arch": [
"ia32",
"x64"
],
"ignore": [
".idea"
]
}
}
}
The version of electron-forge I am using is 3.0.1.
Only the values asar and ignore are recognized, while dir, platform and arch are ignored. I do not see an error and would highly appreciate help, a hint or a link to any working example.
Update:
It has since been suggested here to use the command line for providing these options.
While
electron-forge package --arch=ia32,x64 --platform=win32,linux
does package the app for all the specified systems, although the output looks like this:
✔ Checking your system
✔ Preparing to Package Application for arch: ia32,x64
✔ Compiling Application
✔ Preparing native dependencies
✔ Packaging Application
✔ Preparing to Package Application for arch: x64
✔ Compiling Application
✔ Preparing native dependencies
✔ Packaging Application
✔ Preparing to Package Application for arch: armv7l <-- ???
✔ Compiling Application
✔ Preparing native dependencies
✔ Packaging Application
✔ Preparing to Package Application for arch: x64
✔ Compiling Application
✔ Preparing native dependencies
✔ Packaging Application
It does not seems to actually be packaging the app for the armv7l architecture as it says there, I think that this is just a bug with the console output, the results in the output directory look good.
Anyway.. providing the packaging options via command line does not solve my initial problem, because I still can not specify the dir option for electron-packer that way. So, while the documentation for electronPackagerConfig suggests all options for electron-packer can be set with this configuration object:
This config object provides options directly to electron-packager, the tool we use to package your app behind the scenes.
And while electron-forge package --help says I can set the current working directory after the options:
Usage: electron-forge-package [options] [cwd]
Which is actually not the case, this just simply sets the out directory where everything is written to.
I am still stuck with this. Is there any way to provide the dir option via electron-forge? If not, my suggestion to the developers of electron-forge would be to implement the configuration for this in a way that makes my initial configuration from above work, because I think this is an intuitive way to configurate these parameters, using the command line to override them could still be an option, I guess.
