Fork-ts-checker-webpack-plugin does not seem use the plugins in the tsconfig.json

[wys-evan]

Current behavior

webpack compiles successfully, but fails to check css module when building.

TS2307: Cannot find module './index.module.less' or its corresponding type declarations.

Expected behavior

Can successfully check the css module

Steps to reproduce the issue

1. Project's tsconfig.json configuration :

"plugins": [{   
      "name": "typescript-plugin-css-modules",  
      "options": {  
        "customMatcher": "*.module.(c|le|sc)ss$"   
      }
    }],

2. webpack configuration:

new ForkTsCheckerWebpackPlugin({
         async: false,
         typescript: {
           configFile: path.join(process.cwd(), 'tsconfig.json'),
           configOverwrite: {
             include: [options.packageDir],
           },
           diagnosticOptions: {
             semantic: true,
             syntactic: true,
           },
         },
       })

Unfortunately, TypeScript plugins are supported only in a language service API. I created an issue in TypeScript repo to support plugins in other APIs: microsoft/TypeScript#38736
It seems that TypeScript team has other priorities - my proposal is 2 years old and there is no update.
This plugin supports the same features as tsc - so this behaviour is sadly expected :/
