24.1. Configuring Erlang/OTP versions to test

To use the CI plugin you must first configure which versions -of Erlang/OTP will be used. Erlang.mk provides three separate -configuration variables depending on whether you need a normal -OTP release, a HiPE-enabled release or an ErLLVM-enabled release.

At the time of writing, this is how you would test against all -the most recent patch releases of Erlang/OTP 19 and above:

If you want to test against HiPE and ErLLVM but only with the -latest version of Erlang/OTP, the following could work:
