elixir_test

for debug only Elixir (1.5.1) recompiles the deps codes everytime after I edited my source code(e.g. server.ex). Which I think it is an bug. steps:

1. iex -S mix debug_client
2. edit server.ex source code
3. iex -S mix debug_client

My OS is win7 64. Erlang OTP 20 Anyone pls reproduce the bug. Thanks.
