Reproduction link

Steps to reproduce

1. Create brand new vue-cli 3 application
2. Edit vue.config.js to have this contant:

module.exports = {
  configureWebpack: {
    output: {
      path: path.resolve(__dirname, './other_folder'),
    },
  },
};

3. Run yarn build

Expected build to be successful

What is actually happening?

Command build files, but fails to finish successfully during the formatStats step.

It seems that file path in formatStats.js is hardcoded and doesn't use config from vue.config.js
