The mix.exs file from ecto package contains this complex condition
{:poison, "~> 2.2 or ~> 3.0", optional: true},

For mix projects elixir Version module is used to check deps

iex(1)> Version.parse_requirement("~> 2.2 or ~> 3.0")
{:ok, #Version.Requirement<~> 2.2 or ~> 3.0>}
iex(2)> Version.parse_requirement("~> 2.2")          
{:ok, #Version.Requirement<~> 2.2>}

But, for rebar3 projects in rebar_packages.erl valid_vsn function is used

valid_vsn(Vsn) ->
    %% Regepx from https://github.com/sindresorhus/semver-regex/blob/master/index.js
    SemVerRegExp = "v?(0|[1-9][0-9]*)\\.(0|[1-9][0-9]*)(\\.(0|[1-9][0-9]*))?"
        "(-[0-9a-z-]+(\\.[0-9a-z-]+)*)?(\\+[0-9a-z-]+(\\.[0-9a-z-]+)*)?",
    SupportedVersions = "^(>=?|<=?|~>|==)?\\s*" ++ SemVerRegExp ++ "$",
    re:run(Vsn, SupportedVersions, [unicode]) =/= nomatch.

>valid_vsn("~> 2.2").
true
>valid_vsn("~> 2.2 or ~> 3.0").
false

So,for now, complex conditions in mix.exs are not compatible with rebar3.
Use the mix
$mix new welcome_jambd_oracle --sup

Good, fine with me.
