Webpack Resolver Issue

eslint-plugin-import webpack resolver issue details. Please refer to the project issue to understand the context.

Steps to reproduce

1. Install dependencies

   yarn install

2. Run ESLint

   yarn eslint src

My findings so far

• If I'm using the default webpack config location at <root>/webpack.config.js, I can have the following on my .eslintrc.json

  "settings": {
      "import/resolver": "webpack"
  }

  In this case, it works just fine.

• The issue only occurs when webpack config is not at its default location. I've copied webpack.config.js to webpack.dev.config.js. Then I had to add the following content to my .eslintrc.json:

  "settings": {
      "import/resolver": {
          "webpack": {
              "config": "webpack.dev.config.js"
          }
      }
  }

  When runnign eslint, I get the following error:

  Error resolving webpackConfig Error: Cannot find module '<path>/webpack-resolver-issue/node_modules/date-fns/webpack.dev.config.js'
