Log4j2 logs into user home folder

Question

I'm trying to save log4j2 logs into user home folder because the user has not right to write where the application is installed.

This is the relevant part of my log4j settings. Unfortunately it doesn't resolve user.home and so it creates the folder $user.home where the application is running.

There is a way to solve this issue?

Answer 1

I solved the issue. You sould use ${sys:user.home} instead of ${user.home}.
