Why doesn't rebar compile my files?

It's been a while since I've done any Erlang and I wanted to get back into it and use rebar to do it. I have a simple module-test combo that I've verified compiles okay, but when I try and compile it through rebar, nothing happens:

PS C:\Users\Magnus\Programming\binlog_parser_demo> rebar co -vv
DEBUG: Consult config file "c:/Users/Magnus/Programming/binlog_parser_demo/rebar.config"
DEBUG: Rebar location: "c:/Users/Magnus/Programming/rebar/rebar"
DEBUG: is_rel_dir(C:/Users/Magnus/Programming/binlog_parser_demo) -> false

PS C:\Users\Magnus\Programming\binlog_parser_demo> ls -r

    Directory: C:\Users\Magnus\Programming\binlog_parser_demo

Mode                LastWriteTime     Length Name
----                -------------     ------ ----
d----               3/9     15:42            src
d----               3/9     14:42            test

    Directory: C:\Users\Magnus\Programming\binlog_parser_demo\src

Mode                LastWriteTime     Length Name
----                -------------     ------ ----
-a---               3/9     14:43       2293 binlog_parser_demo.erl

Directory: C:\Users\Magnus\Programming\binlog_parser_demo\test

Mode                LastWriteTime     Length Name
----                -------------     ------ ----
-a---               3/9     14:51       2662 binlog_parser_demo_tests.erl

What am I doing wrong? The file structure is what I got when I ran the template rebar create template=simplemod modid=binlog_parser_demo (and replaced the generated files with my old prewritten ones). I've verified that erlc is in the path and available and that erlc can compile the files okay when run independently.

You need to add a .app.src file to your src directory to define your application. The contents might look something like the following, but you'll need to adjust it to make it work properly for your case.

{application, binlog_parser, [
    {description, "Binlog Parser"},
    {vsn, "0.1"},
    {registered, []},
    {applications, [kernel, stdlib]}
]}.

See the rebar "Getting Started" docs for more information.
