Unable to set crontriggeringpolicy for log4j2

Issue

• Below is my setting in "org.ops4j.pax.logging.cfg", but it failed to function.
• It seems the crontriggeringpolicy and schedule not working, since no log file remain the same.

# Using cron
log4j2.appender.analytics3.type = RollingRandomAccessFile
log4j2.appender.analytics3.name = analytics3
log4j2.appender.analytics3.fileName = ${karaf.data}/log/analytics3.log
log4j2.appender.analytics3.filePattern = ${karaf.data}/log/analytics3_%d{yyyy-MM-dd-HH-mm}.log
log4j2.appender.analytics3.append = true
log4j2.appender.analytics3.layout.type = PatternLayout
log4j2.appender.analytics3.layout.pattern = ${log4j2.pattern}
log4j2.appender.analytics3.policies.type = Policies
log4j2.appender.analytics3.policies.cron.type = CronTriggeringPolicy
log4j2.appender.analytics3.policies.cron.schedule = "0 0/1 * * * ? *"
log4j2.appender.analytics3.strategy.type = DefaultRolloverStrategy
log4j2.appender.analytics3.strategy.max = 7
