Webpack中fileloader不能识别某个特定的文件夹

Question

项目结构图如下：

webpack.common.js如下：

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var helpers = require('./helpers');
var path = require('path');
console.log(helpers.root('public','js'));

module.exports = {
  entry: {
    'polyfills': './src/polyfills.ts',
    'vendor': './src/vendor.ts',
    'app': './src/main.ts',
  },

  resolve: {
    extensions: ['', '.ts', '.js'],
  },

  module: {
    loaders: [
      {
        test: /\.ts$/,
        loaders: ['awesome-typescript-loader', 'angular2-template-loader']
      },
      {
        test: /\.html$/,
        loader: 'html'
      },
      {
        test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)\??.*$/,
        loader: 'file?name=assets/[name].[hash].[ext]'
      },
      {
        test: /\.css$/,
        exclude: helpers.root('src', 'app'),
        loader: ExtractTextPlugin.extract('style', 'css?sourceMap')
      },
      {
        test: /\.css$/,
        include: helpers.root('src', 'app'),
        loader: 'raw'
      },
      {
        test: /\.js$/,
        include: [
          path.resolve(__dirname, "public/js"),
          path.resolve(__dirname, "public/js/ie")
          ],
        loader:'file?name=static/js/[name].[ext]'
      }
    ]
  },

  plugins: [
    new webpack.optimize.CommonsChunkPlugin({
      name: ['app', 'vendor', 'polyfills']
    }),

    new HtmlWebpackPlugin({
      template: 'src/index.html',
    }),
  ]
};

关注最后一个loader，js的loader public/js下的js文件死活没有加载到dist/static/js中。
奇怪的是，我把include去掉（意味着对项目下所有js进行处理），其他的js都加载了，就是public/js下的js不能识别到。请教下各位这是为什么？
