Running brew test erlang returns the following error:

Error: Testing requires the latest version of erlang

Running brew audit --strict erlang returns the following error:

erlang:
* Formula has invalid versioned aliases:
  erlang@22
Error: 1 problem in 1 formula detected

• New formulae should not have a bottle do block

[fxcoudert]

We have too many versioned erlang formulas in core, we need to remove some of the older ones (17 and 18).

[tomciopp]

@fxcoudert Updated code

[fxcoudert]

We need to determine whether riak can be compiled with a more recent erlang version

[tomciopp]

@fxcoudert basho/riak#978

[tomciopp]

@fxcoudert So it looks like we still need to keep the older versions of erlang based on the response from the riak people. If I add 17 back, should I add 18 as well?

[tomciopp]

@fxcoudert Bumping this, how should we proceed?

[fxcoudert]

@tomciopp restore erlang 17, leave erlang 18 out, and we should be good

[tomciopp]

@fxcoudert Done

@tomciopp Can you bump this to OTP 22.0.1? It was released a day or two after to fix an important ssh issue: https://github.com/erlang/otp/releases/tag/OTP-22.0.1

erlang.org is just always a bit behind on minor release announcements

[tomciopp]

@archseer Will update.

@tomciopp Correct end of files please(https://jenkins.brew.sh/job/Homebrew%20Core%20Pull%20Requests/42314/version=high_sierra/testReport/)

erlang@17:
  * File should end with a newline

[fxcoudert]

Please squash your changes into three commits:

• erlang@18: delete
• erlang 22.0.1 for the main formula update (and alias rename)
• erlang@21 21.3.8 (new formula) for the new Erlang 21 formula

[tomciopp]

@fxcoudert Updated

[tomciopp]

@fxcoudert bumping, can we merge?
