How to exclude files from bundling in aurelia.json - aurelia

Question

I'd like to prevent src/config.js to be bundled in scripts/app-bundle.js
I saw that previously the syntax was:
"bundles": {
"dist/app-build": {
"includes": [
"[**/*.js]",
"**/*.html!text",
"**/*.css!text",
"cloneya",
"dexie",
"jquery",
"jquery-ui",
"medium-editor-webpack",
"moment",
"polymer/mutationobservers",
"safe-json-stringify"
],
excludes: [
"config.js" // So our wildcard globbing doesn't include this config file
],
...
However the new syntax is different: aurelia.json:
"bundles": [
{
"name": "app-bundle.js",
"source": [
"[**/*.js]",
"**/*.{css,html}"
],
"excludes" : [
"**/config.js"
]
},
My temptative 'exclude' statement doesn't do the trick

Solution is actually given on the GitHub page: https://github.com/aurelia/cli
Optionally, you can define an exclude list by setting the source
property to be an object containing both an include and exclude array
of patterns. This is helpful when you're trying to define multiple
bundles from your source code.
{
"name": "app-bundle.js",
"source": {
"include": [
"[**/*.js]",
"**/*.{css,html}"
],
"exclude": [
"**/sub-module/**/*",
]
}
},
{
"name": "sub-module-bundle.js",
"source": [
"**/sub-module/**/*",
]
}
Make sure you have version > 0.19.0
