I had checked the doc of erlang-mode.

it's seem that C-c C-k, (erlang-compile) - Compiles the Erlang module in the current buffer.

just compile one file of current buffer. I wanna compile a project with rebar commond on emacs. eg. ./rebar compile

and it can display result like execute "erl -sname -pa ebin -pa deps/*/ebin".

how to do this on emacs?

Doing this the "right" way involves inferior emacs shells and such, and isn't trivial. But you can mostly get the desired effect with these two steps:

  1. At the top level of your project directory, which you can get to by visiting your rebar.config file, execute M-x compile and after hitting enter, change the compile command to rebar get-deps compile, then hit enter to run it.

  2. Assuming the compilation in the first step succeeds, execute C-u M-x erlang-shell and hit enter. It will prompt you for the shell arguments, which should be

    erl -pa deps/*/ebin -pa ebin

    Hit enter and you'll get an erlang shell prompt, with its erlang load path properly set up for your project.
