I used chainWebpack, eg:

module.exports = function (config, { webpack }) {
  config.merge({
    plugin: {
      'banner': {
        plugin: webpack.BannerPlugin,
        args: [
          {
            entryOnly: true,
            banner: `${process.env.npm_package_name} v${process.env.npm_package_version}\n` +
                '(c) 2019 +v\n' +
                'Released under the MIT License.'
          }
        ]
      }
    }
  });
}

it never work.

and I found node_modules/af-webpack/lib/getConfig/uglifyOptions.js:59 comments: false,

so what can I do now?

use uglifyjs-webpack-plugin instead

chainWebpack(config, { webpack }) {
  config.merge({
    plugin: {
      install: {
        plugin: require('uglifyjs-webpack-plugin'),
        args: [{
          sourceMap: false,
          uglifyOptions: {
            compress: {
              // remove `console.*`
              drop_console: true,
            },
            output: {
              // whether to actually beautify the output
              beautify: false,
              // remove all comments
              comments: false,
            },
          }
        }]
      }
    }
  })
}
