rebar3 auto works for the first save, then crashes.

[carlotm]

I added the plugin in the correct config file (the global one).

$ cat ~/.config/rebar3/rebar.config 
{plugins, [rebar3_auto]}.

Running rebar3 auto works fine for the first save, then it crashes.

$ rebar3 auto

Looks like #23 but the solution proposed there didn't work for me.

Is this rebar3_auto crashing, or your supervisor tree crashing? Remember rebar3 does a hard purge, forcing all processes executing changed code to crash.
