I am new with Ejabberd and Erlang and I am trying to add this module. I made the changes like I replace the jlib.hrl with xmpp.hrl and replace the packet by the message as suggested in this answer my issue is whenever I am trying to compile it say xmpp.hrl and ejabberd.hrl is not found how can I solve this issue.
I want to send the FCM notification to the offline user if some trying to send a message to him. am I doing right? or there have some other best ways to achieve this
ejabberd.hrl was removed a year ago: https://github.com/processone/ejabberd/commit/fd8e07af4789be362a61755ea47f216baeb64989
Download ejabberd source code, copy mod_offline_post.erl to the src/ dir, and make your changes, including those two:
diff --git a/src/mod_offline_post.erl b/src/mod_offline_post.erl
index 312278dc0..f4e6f79a1 100644

-define(PROCNAME, ?MODULE).
--include("ejabberd.hrl").
--include("jlib.hrl").
+-include("xmpp.hrl").
-include("logger.hrl").
-include("mod_muc_room.hrl").
Then compile and install ejabberd.
