ERROR StatusLogger Log4j2 could not find a logging implementation

if you already added log4j-core to maven pom, you dont need anything more it should work. Problem could be with your IDE, that does not see your maven dependency. Try reloading or reimporting maven dependencies, or restarting your IDE also can help.

Solved the error message by setting the system property for log4j2 configuration file. below is the below code.

System.setProperty("log4j.configurationFile","./path_to_the_log4j2_config_file/log4j2.xml");

Logger log = LogManager.getLogger(LogExample.class.getName());

This dependency help to avoid this error from lambda.

    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-to-slf4j</artifactId>
    <version>2.8.2</version>
