Nightwatch E2E tests fail with an extract-text-webpack-plugin error when importing styles in a DLL

Version

3.0.0-beta.6

Reproduction link

https://github.com/davidwallacejackson/vue-cli-css-import-repro

Steps to reproduce

1. npm install
2. npx vue-cli-service e2e

What is expected?

The automatically-generated E2E tests should pass.

What is actually happening?

The E2E tests time out. In the browser console, there's an error: "extract-text-webpack-plugin" loader is used without the corresponding plugin

---

vue.config.js is configured to prebuild '@/module-importing-css' into a DLL, which is then referenced from main when it imports './module-importing-css'. If you comment out that line in the config, the tests run correctly.

There's another issue about people encountering this same error (#997) but the context seems very different (they're using Windows and they're not running e2e tests), so I wasn't sure the error was actually caused by the same bug in both cases.

Closing as we will be removing the DLL option.

[davidwallacejackson]

Fair enough. Could I ask why you're removing it? It was a big help for my project, though it wouldn't be the end of the world to set the plugin up manually.

We will be upgrading to webpack 4 which has better build performance so the return from maintaining the extra DLL option no longer justifies the cost.
