],
"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'
}
]]]
