It's saying Set is not defined on copy-webpack-plugin which is little strange.

Webpack Config:

Note: This is not the entire config file.

var path = require('path');
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require("extract-text-webpack-plugin");
var CopyWebpackPlugin = require('copy-webpack-plugin');
var CleanWebpackPlugin = require('clean-webpack-plugin');
var ProvidePlugin = require('webpack/lib/ProvidePlugin');

module.exports = {
  debug: true,
  entry: {
    vendor_angular: ["angular","angular-ui-router","angular-sanitize"],
    bundle: ['./src/app.js'],
  },
  // entry: ['babel-polyfill', './src/app.js'],
  output: {
    path: path.join(__dirname, 'public'),
    filename: '[name].js'
  },
  devServer: {
    // This is required for webpack-dev-server. The path should
    // be an absolute path to your build destination.
    outputPath: path.join(__dirname, 'public')
  },
  plugins: [
    new CopyWebpackPlugin([
      { from: 'src/**/*.js', to: __dirname + '/public' },
      { from: 'src/**/*.png', to: __dirname + '/public' },
      { from: 'src/**/*.svg', to: __dirname + '/public' },
      { from: 'src/**/*.json', to: __dirname + '/public' },
      { from: 'src/**/*.jpg', to: __dirname + '/public' },
      { from: 'src/**/*.mp4', to: __dirname + '/public' },
      { from: 'src/**/*.gif', to: __dirname + '/public' },
      { from: 'src/**/*.wav', to: __dirname + '/public' }
    ]),
    new CleanWebpackPlugin(['public'], {
      root: path.resolve(__dirname),
      verbose: true,
      dry: true
    }),
      ],
  module: {
   },

  devtool: 'source-map'
};

Has anyone encountered similar error. How should I track down what is causing the build to fail.

What version of `copy-webpack-plugin` are you using? It wouldn't fix the `Set is not defined` directly, but `copy-webpack-plugin` is not using `Set` at all, it has been removed in the commit [82052dd](https://github.com/kevlened/copy-webpack-plugin/commit/82052dd#diff-1fdf421c05c1140f6d71444ea2b27638) (a year ago), which was in v3.0.0 and the latest version published to npm is [v4.0.1](https://www.npmjs.com/package/copy-webpack-plugin). — Michael Jungo, Mar 28 '17 at 23:35
