Hello everyone 
I am trying to get ionic to build my android app in my CI environment, but I must be doing something wrong.
The CI performs a clean clone from Git, and these are the overall contents of Git:
- package.json does NOT have dependency on cordova-android;
- platforms, inside cordova, inside package.json is empty;
-
config.xmlonly has<platform name="android"><allow-intent href="market:*" /></platform>related to android, everything else is same as generated byionic start;
I am using yarn to download my npm dependencies.
My CI script runs the following:
- yarn config set cache-folder .yarn
- yarn
- ionic info
- ionic cordova platform add android
- ionic cordova resources android
- ionic cordova build android --prod
The problem is that on my CI environment, the ionic cordova platform add android command fails, with the following output:
$ yarn
yarn install v1.3.2

If I run this command in my Windows 10 machine (after deleting cordova-android from node_modules, and deleting the platform folder, and making sure that the platforms array is empty in package.json), I get the expected output:

This is almost driving me insane hehe. The major difference is that the OS in my CI is Linux (alpine based) and in my dev computer I have Windows 10…
I am scratching my head about the output line in my CI “Adding zone.js project …”… where the heck did this come from? It should say (like my windows machine) “Adding android project…”
Searching around in the interwebs told me to run ionic platform rm android followed by ionic platform add android, but this doesn’t solve the problem.
Any pointers will make my tomorrow greatly better than my today ended. 
Thank you in advance.
