Removing all other comments

If you want to remove all other comments, use uglifyjs-webpack-plugin instead of plugins in webpack.

$ npm install uglifyjs-webpack-plugin --save-dev

const UglifyJSPlugin = require('uglifyjs-webpack-plugin');

and also you must be set behind UglifyJSPlugin.

// ...
  plugins: [
    new UglifyJSPlugin(),
    new LicenseBannerPlugin()
  ]
// ...

production mode (at webpack v4)

mode option has added from webpack v4.

If you use production mode and also want to use license-banner-webpack-plugin, you must set optimization.minimize option to false.

// ...
  mode: 'production',
  optimization: {
    minimize: false
  }
// ...
