angular-cli run command after ng build : <p>I am wondering how to extend ng build to run tasks after it has finished. </p>

<p>At the moment, my end goal is to copy my 'package.json' to the dist folder. </p>

<p>Something like this if I was using plain npm:</p>

<pre><code>"postbuild": "cpx ./package.json ./dist/",
</code></pre>

<p>I know in the angular-cli.json I can use "assets" to copy static files, but it does not work for files outside of src. So, I'm wondering if I can do the copy task after ng build completes. </p>
