Not sure if this should be rebar3 issue https://github.com/erlang/rebar3/blob/3.11.1/src/rebar_state.erl#L481. Should format_error be called here ?

• error appears to be on windows
• error is triggered at https://github.com/tsloughter/rebar_mix/blob/765136e69a7d54e1015a05888327af0f53b24b27/src/rebar_mix_elixir_finder_hook.erl#L47-L48
• this might be related to return codes where sometimes a non-0 status (read as an error) is actually good for some command
• see https://github.com/erlang/rebar3/blob/dab233d6edeef2e15b8fcd4616ac01fbaea7e664/src/rebar_file_utils.erl#L351-L353 for an example

It needs confirmation on whether running the same shell command returns a status code that fits the range there, but if so, that would explain it.

From Slack:

It has been fixed in master
using the master this error is not reproducible. But it seems like master is not tagged and pushed to hex

[shamis]

closing the issue as only thing to be done is to tag and push to hex
