Compilation Error: Cyclical Module Declaration

Environment

• Elixir & Erlang versions (elixir --version):

Current behavior

When compiling a project that depends on ex_aws, I get the following error:

==> dynasaur
Compiling 36 files (.ex)

== Compilation error in file lib/dynasaur/dynamo/jt_team.ex ==
** (CompileError) lib/dynasaur/dynamo/jt_team.ex:3: cannot define module ExAws.Dynamo.Decodable.Kernel because it is currently being defined in lib/dynasaur/dynamo/project_preference.ex:3
    lib/dynasaur/dynamo/jt_team.ex:3: (module)

Expected behavior

The module compiles correctly.

I have no idea what dynasaur is, but it isn't part of ExAws so I can't really help you with compilation errors in it.
