eslint imports in webpack: Unable to resolve path to module

With eslint-import-resolver-webpack I'm trying to let eslint know that I want to import files, by referencing a "shortcut" (eg. components/Counter).

In the example below, webpack (v2.2.0-rc.3) builds fine, but the test fails because it's "Unable to resolve path to module 'components/Counter'". I get this error also for importing 'components/Counter/reducer', so it's not limited to index.

Both running npm run lint and my IDE (IntelliJ) give the same error.

Following the docs, I've set the following configs:

(Part of) file structure:

project-root/
  app/
    components/
      Counter/
        index.js
        reducer.js
    app.js
 internals/ 
   config/
      .eslintrc
      webpack.test.js
  package.json

File: project-root/app/app.js

import Counter from 'components/Counter'
// etc...

"lint:eslint": "eslint -c internals/config/.eslintrc --fix --ignore-path .gitignore --ignore-pattern internals"

And: project-root/internals/config/webpack.test.js:

const webpack = require('webpack')

module.exports = {
  devtool: 'inline-source-map',

  module: {
    loaders: [
      { test: /\.json$/, loader: 'json-loader' },

      { test: /\.css$/, loader: 'null-loader' },

      { test: /\.js$/,
        loader: 'babel',
        exclude: [/node_modules/],
      },

      { test: /\.jpe?g$|\.gif$|\.png$|\.svg$/i,
        loader: 'null-loader',
      },
    ],
  },

  plugins: [
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: JSON.stringify(process.env.NODE_ENV),
      },
    }),
  ],

  resolve: {
    modules: [
      'app',
      'node_modules',
    ],
  },
}

Note: I've also tried pointing to a file that only exports the resolve object. Same thing:

module.exports = {
  resolve: {
    modules: [
      'app',
      'node_modules',
    ],
  }
}

It seemed my dependencies needed updating...

There's quite a lot of plugins, configs, etc needed for a thorough linting process..

-- edit --

Here's an excerpt of my projects' dependencies. There might be some packages in here that are not necessary, I removed only the ones of which I'm sure that don't have an impact.

Note that front-end land moves like a cheetah in 6th gear, so the versions might get outdated soon. Anyway, as of now (feb 2017) this is a working configuration.

"dependencies": {
    "babel-polyfill": "6.16.0",
    "react": "15.4.2",
    "react-dom": "15.4.2",
  },
  "devDependencies": {
    "babel-cli": "6.18.0",
    "babel-core": "6.21.0",
    "babel-eslint": "7.1.0",
    "babel-loader": "6.2.10",
    "babel-plugin-react-transform": "2.0.2",
    "babel-preset-es2015": "6.18.0",
    "babel-preset-react": "6.16.0",
    "babel-preset-stage-3": "6.17.0",
    "babel-register": "6.22.0",
    "eslint": "3.13.1",
    "eslint-config-airbnb": "14.0.0",
    "eslint-import-resolver-webpack": "0.8.0",
    "eslint-plugin-import": "2.2.0",
    "eslint-plugin-jsx-a11y": "3.0.2",
    "eslint-plugin-react": "6.9.0",
    "eslint-plugin-redux-saga": "0.1.5",
    "webpack": "2.2.0",
    "webpack-dev-middleware": "1.9.0",
    "webpack-hot-middleware": "2.14.0"
  }
