Can't find include file "logger.hrl"

[vkrm26]

Hi, First of all thanks.
I'm having issue on Navigate to the mod_log_chat_mysql5 directory in the ejabberd-modules folder and call ./build.sh step. After running this script i'm getting following messages -

ejabberd-modules/mod_log_chat_mysql5$ ./build.sh
Recompile: src/mod_log_chat_mysql5
src/mod_log_chat_mysql5.erl:26: can't find include file "logger.hrl"
src/mod_log_chat_mysql5.erl:129: Warning: variable 'Info' is unused

Though I had taken changes from - Make module working for newer ejabberd versions.
But still getting same errors.
Could you please suggest how can i resolve this issue?
I have checked Erlang version its - R16B03

What happens if you copy logger.hrl from the ejabberd sources to the module directory?
