Old PLT file?

[Yao Bao]

Hello,

More detailed information/logging message might be helpful to determine this.

Since PLT comes from Erlang, and you are using Elixir, you should check who is complaining “old”.

And since this involves CI within GitHub, you might check how you “cache” the PLT file as well.

I have no documentation at hand, might it be documented somewhere?
(dialyzer related I guess)

We very seldom change versions of OTP or Elixir, nor do our dependency versions change very often, yet we get into this situation a lot more often than I believe we should. If I could understand a little better about what makes a PLT old, perhaps I could solve this issue.
