Ionic --prod Android

Im trying to create a deploy apk using the following command: “ionic cordova build android --prod”, but it takes too long, and on the final doesnt creat any apk for Android.

The output:

Running app-scripts build: --prod --platform android --target cordova

The ionic info is:

@ionic/cli-plugin-proxy : 1.5.6
@ionic/cli-utils : 1.19.0
ionic (Ionic CLI) : 3.19.0
global packages:

cordova (Cordova CLI) : 7.0.1

local packages:

@ionic/app-scripts : 3.1.2
Cordova Platforms  : android 6.2.3 ios 4.5.3
Ionic Framework    : ionic-angular 3.9.2

System:

Android SDK Tools : 26.0.2
Node              : v8.9.1
npm               : 5.3.0
OS                : Windows 8.1

Any idea of what can be?

The correct command would be ionic cordova build android --prod --release - --prod only produces and optimized build, --release is for release versions of apps.

This is very strange.
