I try to configure logger to write line number but instead of it I have question.
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p [%t]:%L - %m%n
I figured out that it is not log4j problem but setting of my project. The most probably missing debug information in my compiled artifacts. (Line number not showing?) But how can I set that in IntellijIdea 2019.1?
