log4j2 Not Creating RollingFile Logs

I have just started using log4j2 with slf4j2 but I'm facing a problem where I'm trying to create rolling log files on daily basis. I am able to create an active log file but when I change the system date by one day, logging happens on the same active file which I thought it should have archived previous days' logs to another file.

Following is the log4j2.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="ERROR" monitorInterval="5">
	<Properties>
		<Property name="log-path">${sys:catalina.base}/logs</Property>
	</Properties>
	<Appenders>
		<Console name="Console" target="SYSTEM_OUT">
			<PatternLayout
				pattern="%d{dd-MMM-YYYY HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
		</Console>
		<RollingFile name="file-gen" fileName="${log-path}/demopro.log"
			filePattern="${log-path}/%d{yyyy-MM}/demopro-%d{dd-MM-yyyy}.log.gz">
			<PatternLayout
				pattern="%d{dd-MMM-YYYY HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
			<Policies>
				<TimeBasedTriggeringPolicy interval="1" modulate="true" />
			</Policies>
		</RollingFile>
	</Appenders>
	<Loggers>
		<Root level="info">
			<AppenderRef ref="Console" />
		</Root>
		<Logger name="org.hkb.tryone" level="debug" additivity="false">
			<AppenderRef ref="Console" />
		</Logger>
		<Logger name="org.hkb.trytwo" level="info" additivity="false">
			<AppenderRef ref="Console" />
			<AppenderRef ref="file-gen" />
		</Logger>
	</Loggers>
</Configuration>

What am I doing wrong here ?!

I think your filePattern can only have one %d variable. If you have two, the rollover policy cannot determine the rollover frequency.

So, replace what you have now:

filePattern="${log-path}/%d{yyyy-MM}/demopro-%d{dd-MM-yyyy}.log.gz">

with this:

filePattern="${log-path}/$${date:yyyy-MM}/demopro-%d{dd-MM-yyyy}.log.gz">
