javascript - webpack 不加载依赖项

Question

我遇到了一个问题，我包含了一个 jQuery 插件 (jquery.jplayer.js)，并且 webpack 正在同一文件中加载该插件的依赖项，在本例中是 jQuery。我想通过 CDN 提供 jQuery 服务，所以显然我也不希望 jQuery 在本地加载。我已将其范围缩小到这行代码 define(['jquery'],factory);//jQuery 开关.

如何告诉 webpack 不包含在 .js 文件中找到的依赖项？

var debug = process.env.NODE_ENV !== "production";
var webpack = require("webpack");
var path = require("path");

module.exports = {
    context: __dirname,
    devtool: debug ? "inline-sourcemap" : null,
    entry: {
        app: "./wwwroot/js/app.js",
        lib: "./wwwroot/lib/jPlayer/dist/jplayer/jquery.jplayer.js"
    },
    module: {
        loaders: [
          {
              test: /\.jsx?$/,
              exclude: /(node_modules|bower_components)/,
              loader: "babel-loader",
              query: {
                  presets: ["react", "es2015", "stage-0"],
                  plugins: ["react-html-attrs", "transform-class-properties", "transform-decorators-legacy"],
              }
          }
        ]
    },
    output: {
        path: "./wwwroot/build/",
        filename: "[name].js"
    },
    plugins: debug ? [] : [
      new webpack.optimize.DedupePlugin(),
      new webpack.optimize.OccurenceOrderPlugin(),
      new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false })
    ]
};

此代码将 jQuery 排除在捆绑之外:

externals: {
  "jquery": "jQuery"  
},
