you can defind your own localIdentName in pluginOptions.cssLoaderOptions.modules.getLocalIdent

  options: {
  lessVarsFilePath: './src/styles/variables.less'
  // ...

How to overwrite antd less variables?

// ./src/styles/variables.less
@import '~antd/lib/style/themes/default.less'; // <-- you need to import antd variables once in your project

@primary-color: #04f; // change antd primary-color
// 🔰️ Tips: if your use babel import plugin and set `libraryDirectory`, please keep `libraryDirectory` and `less path` consistent.

// lib
['import', { libraryName: 'antd', libraryDirectory: 'lib', style: true }]
// `@import '~antd/lib/style/themes/default.less';` <-- use `lib`

// es
  ['import', { libraryName: 'antd', libraryDirectory: 'es', style: true }]

Background

Issues

Since Next.js 9.3 supports sass and css by default, but does not support less. If you use Next.js > 9.3 and use the official less plugin, you will definitely encounter the following problems.

  1. CIL Warning Warning: Built-in CSS support is being disabled due to custom CSS configuration being detected.

  2. Does not support automatic recognition of css modules, e.g. a.module.less and a.less

Solution

  1. Find sassModule and copy onec and replace the sass-loader inside with less-loader.

  2. Then enable the modules.auto option of css-loader. This can simply match all *.less (no need to match it is *.module.less or *.less), and hand it over to css-loader.

This is the lowest cost way, And CLI will no longer show this disgusting warning. The important thing is that there is Zero Dependency on other Next-Plugins..
