Support older versions of eslint & plugins moving forward?

[jakemhiller]

The recent updates to eslint-config-airbnb and eslint-plugin-react caused a lot of issues as our team all of the sudden had branches failing that were previously passing.

I'm wondering if there is a way for you to support using older versions of eslint and the supported parsers/plugins moving forward.

It seems like you support older versions of rubocop through the codeclimate.yml config, just wondering if there were plans to extend this to eslint eventually.
#76 is related, as this will break compatibility with a lot of rules (afaik).

Hi @jakemhiller,

We recently introduced the concept of channels to Code Climate engines which will allow us to support multiple versions of ESLint and supported plugins moving forward.

The default channel is stable which currently targets ESLint v1. The other currently available channel is eslint-2 which you can opt-in to by updating your .codeclimate.yml configuration file:

engines:
  eslint:
    enabled: true
    channel: eslint-2

Looking forward a bit, we'll eventually update the stable channel to target ESLint v2, but will give users the option to pin to ESLint v1, likely with an eslint-1 channel.

Hope that helps! Let me know if you have any further questions.

Great news, thanks!
