There are places, typically in rebar boss_plugin where "./deps" are expected to exists.
(Of course, when one app needs another version of dependencies than another one, these cases are to be solved individually.)
Another thing is that even if the CB itself is a dependency in (expected "deps" dir), it is necessary to write "./deps/boss" in boss.config instead of "deps/boss" -- just a note, no big deal. Leaving boss path emty defaults back to (expected) "deps" dir...
I think this is a property of Rebar, can you be more specific in what you think it should do and what it is doing (and when)
too old, please reopen if issue still exists
