How to exclude modules from sourcemap in webpack 2?

Question

JavaScript

Hello.
The project uses webpack 2 which bundles .js. Sourcemaps are generated during assembly:

// webpack.config.js

{
  ...
  devtool: 'source-map',
  ...
  plugins: [
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true
    })
  ],
  ...
}

The project also uses N-number of libraries, which are compiled into one bundle with the rest of the project scripts. The question is: is it possible (and is it possible at all?) to exclude some libraries from sourcemaps? Something like:

new webpack.optimize.UglifyJsPlugin({
  sourceMap: true
  sourceMapExclude: ['jquery', 'react', 'lodash', 'backbone']
})

Try:

new webpack.SourceMapDevToolPlugin({
  filename: "[file].map",
  exclude: ["vendors.js"]
})

instead ofdevtool: 'source-map',
