The rebar3_hex plugin should be something you install globally, not 
something you put in your repo.

The latest rebar3_hex version only works with rebar 3.9.1 and later due 
to vendoring issues of core libraries interacting with hex.pm. We had 
the first problems with this around January, and finally solved it (with 
the help of community contribution) in a way that should be safe later.  
It unfortunately still causes issues when interacting with older rebar3 
versions.

You will therefore want to either use an older rebar3_hex version, or a 
newer rebar3 version.
