  ],
  "plugins": [["import-fix", [
    {
      'libraryName': 'xcui',
      'libraryPath': 'xcui/lib/${name}.js',
      'namePolicy': 'dash',
      'cssPath': ['xcui/lib/css/common.css', 'xcui/lib/css/${name}.css']
    },
    {
      'libraryName': 'antd',
      'libraryPath': 'antd/lib/${name}/index.js',
      'namePolicy': 'dash',
      'cssPath': 'antd/lib/${name}/style/index.css'
