Webpack config

var webpackMerge = require('webpack-merge');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var commonConfig = require('./webpack.common.js');
var helpers = require('./helpers');
var ngtools = require('@ngtools/webpack');
var AotPlugin = ngtools.AotPlugin;

const ENV = process.env.NODE_ENV = process.env.ENV = 'production';

module.exports = webpackMerge(commonConfig, {
    devtool: 'source-map',

    output: {
        path: helpers.root('../../../target/rhamt-web'),
        filename: 'js/[name].js',
        chunkFilename: 'js/[id].chunk.js'

                loaders: '@ngtools/webpack'

    plugins: [
        new webpack.NoEmitOnErrorsPlugin(),
        new ExtractTextPlugin('css/[name].css'),
        new AotPlugin({
            tsConfigPath: './tsconfig-production.json',
            basePath: '.',
            mainPath: 'src/main.ts',
            skipCodeGeneration: true
        }),
        new webpack.optimize.UglifyJsPlugin({ // https://github.com/angular/angular/issues/10618
            mangle: {
                keep_fnames: true
            }
        }),
        new webpack.DefinePlugin({

                'ENV': JSON.stringify(ENV)
            }
        })
    ]
});

main.ts

import {platformBrowserDynamic} from "@angular/platform-browser-dynamic";
import {NgZone, enableProdMode} from "@angular/core";
import {AppModule} from "./app/app.module";

require('./keycloak.json.ftl');
require('../css/windup-web.css');

if (process.env.ENV === 'production') {
    enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule).then(app => {
    // this is just here to make some data easier to retrieve from tests
    window["app"] = app;
    window["MainNgZone"] = app.injector.get(NgZone);
    if (window["windupAppInitialized"] != null)
        window["windupAppInitialized"](app, window["MainNgZone"]);
})
.catch(err => {
    console.log(err);
    if (window["windupAppInitialized"] != null)
        window["windupAppInitialized"]();
});

Desired functionality.

@angular/compiler module should not be present in AOT builded app.

You have the skipCodeGeneration: true turned on, which disables AOT builds and instead gives you a JIT build that does require the compiler at runtime. Set skipCodeGeneration: false and that should give you an AOT build that doesn’t require the compiler.
