When Codacy didn't provide a PMD engine I created my own called https://docs.codeclimate.com/docs/apexmetrics. It was for Salesforce apex classes only and suffered from me being the bottleneck to maintain and upgrade it.

By accident I learned that Codeclimate now has an all-languages PMD engine.

If this engine works with all languages, I'd like to:

1. Have Codeclimate take my engine out of their site. @brynary @dblandin
2. Remove my own engine repo
3. Get somewhat a safe feeling from Codeclimate that users of my engine are safe ;-)
4. Take out the Codeclimate specific parameters and dependancies I introduced to PMD Apex rules
