I would like to present rebar3 projects as illustration of author's source code ideas - projects.
Going through the book and was trying this example in chapter 11.
I cloned this repo, navigated to the ch11/ex3-drop-app
folder and ran the following:
Erlang/OTP 20 [erts-9.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V9.2 (abort with ^G)
1> c(drop_app).
{ok,drop_app}
2> code:add_path("ebin/").
true
3> application:load(drop).
ok
4> application:start(drop).
{error,{bad_return,{{drop_app,start,[normal,[]]},
{'EXIT',{undef,[{drop_sup,start_link,[],[]},
{application_master,start_it_old,4,
[{file,"application_master.erl"},{line,273}]}]}}}}}
