CLI v3 custom flags not passed to command

After upgrading ionic from 2.0.0-rc-5 to 3.6.0 my custom rollup config has stop receiving my custom flag when i build to a platform. It does works for ionic serve and ionic build command.

before v2.0.0-rc5 (worked)

ionic build ios --production

after (v3.6.0)

ionic build --production
# console logs
Running app-scripts build: --production

ionic cordova build ios --production
# console logs
Running app-scripts build: --address --port 8100 --p 8100 --livereload-port 35729 --r 35729 --iscordovaserve --nobrowser

Did you upgrade Ionic (Framework, ionic-angular) or Ionic CLI?

I think the CLI has a “whitelist” of commands for ionic cordova build or something…

i updated both the cli and ionic-angular

Jsut for my understanding: How do you handle and what do you do with this flag? (I am not accustomed with rollup)

i use the flag to change the app’s environment variables.

var nodeResolve = require('rollup-plugin-node-resolve');
var commonjs = require('rollup-plugin-commonjs');
var globals = require('rollup-plugin-node-globals');
var builtins = require('rollup-plugin-node-builtins');
var json = require('rollup-plugin-json');
var replace = require('rollup-plugin-replace');
var argv = require('yargs').argv;
var isProd = false;
  console.log('=====> configuring for production');
  isProd = true;


var rollupConfig = {
   * entry: The bundle's starting point. This file will
   * be included, along with the minimum necessary code
   * from its dependencies
  entry: process.env.IONIC_APP_ENTRY_POINT,

   * sourceMap: If true, a separate sourcemap file will
   * be created.
  sourceMap: process.env.IONIC_GENERATE_SOURCE_MAP ? true : false,

   * format: The format of the generated bundle
  format: 'iife',

   * dest: the output filename for the bundle in the buildDir
  dest: process.env.IONIC_OUTPUT_JS_FILE_NAME,

   * plugins: Array of plugin objects, or a single plugin object.
   * See for more info.
  plugins: [
        exclude: 'node_modules/**',
        // use the /config/environment-dev as the default import(!), no stub needed.
        // note we only replace the "last" part of the import statement so relative paths are maintained
        '/config/' : ( isProd ? '/config/' : '/config/'),
      module: true,
      jsnext: true,
      main: true,
      browser: true,
      extensions: ['.js']


module.exports = rollupConfig;

Thanks for explaining.
