Unfortunately rebar3 was not in the docker container for our CI builds, which means erlang wasn't being built at all, and it looks like erlang is now completely broken. Whether using OTP 20 or OTP 22, erlang doesn't work with any of the other languages.
This can be seen in the latest pull request for CI updates: https://github.com/apache/thrift/pull/1817 It is easily reproducible inside the docker build container. If someone who knows erlang could look into this, it would be great. We cannot start the 0.13.0 release cycle with a regression like this. - Jim
