.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I'm using the pcap4j library in my application and when I run it I get:
log4j:WARN No appenders could be found for logger (org.pcap4j.core.NativeMappings).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
I also use log4j in my application:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.11.1</version>
</dependency>
which is configured in main/resources/log4j2-test.properties:
log4j.rootLogger=INFO, fileLogger
log4j.appender.fileLogger.layout=org.apache.log4j.PatternLayout
log4j.appender.fileLogger.layout.ConversionPattern=%d [%t] %-5p (%F:%L) - %m%n
log4j.appender.fileLogger.File=application.log
log4j.appender.fileLogger=org.apache.log4j.DailyRollingFileAppender
log4j.appender.fileLogger.datePattern='.'yyyy-MM-dd-HH-mm
So the configuration file is there and whatever I change in it it has an effect which means log4j sees it and it works, so I'm quite helpless when I read everywhere that this kind of warning is caused by a missing or wrong config file.
Can it be that the error is in the dependency and I can't do anything about it? If so, is there a way to disable the logging in this dependency completely? Actually this is that I would want in the first place anyway.

That message is from log4j 1, whereas you are using log4j2, therefore it is harmless.

void emitNoAppenderWarning(Category cat) {
// No appenders in hierarchy, warn user only once.

You can manually set the log config file using this :

The <path> can either be absolute or relative to the root of your maven module.
