[erlang-questions] Error with ./rebar generate: "erlsom: Application version clash. Multiple directories contains version \"1.2.1\"

[Dániel Szoboszlay]

Hi,

The error message means the erlsom application was found in multiple directories. I guess the lib_dir option in {app, erlsom, [{incl_cond, include},{lib_dir,"../deps/erlsom"}]} confuses reltool (you normally don’t need this option for dependencies, rebar tells reltool where to find them), or maybe there’s an other copy at ../erlsom (as you declare .. as a lib_dir in reltool.config)?

Regards.
Daniel
