asar target and prepackaged option support for it

• electron-builder 11.2.3:

• OSX:

Builder crashes when trying to package app with --prepackaged command with the following error:

Error: ENOENT: no such file or directory, 
open '/Users/pro/repository/desktop_app/dist/mac/Desktop.app/Contents/Resources/app-update.yml'
at /Users/pro/repository/desktop_app/node_modules/electron-builder/src/macPackager.ts:101:13

In my package.json: {"dist": "npm run compile && build --prepackaged ./asar"} where ./asar is the folder containing app.asar, core.asar and node_modules.asar files

What I want is to be able to point electron-builder into a folder containing app.asar and it would package the apps for distribution.

Thanks @develar for checking out the code. Leaving a comment here if someone has the same issue (this should be documented somewhere eventually)

Important bit is to specify the electronVersion and projectDir parameters. Working example:

import * as builder from 'electron-builder';
let config = {
    appId: 'com.asar.test',
    directories: {
        buildResources: './build_resources'
    },
    electronVersion : '1.5.0'
}
builder.build({
    projectDir: './path/to/folder/with/asar/files',
    config: config
}).then(() => {
    console.log('done');
}).catch((error) => {
    console.log(error);
})
