Description
The page Log4j 2 SLF4J Binding mentions under Usage that...
Simply include the Log4j 2 SLF4J Binding jar along with the Log4j 2 jars to cause all SLF4J logging to be handled by Log4j 2.
...and under Requirements only that...
The Log4j 2 SLF4J Binding requires at least Java 6 and has a dependency on the Log4j 2 API.
But this is actually not the case since the API classes from the package org.slf4j.* are not bundled within the binding JAR.
The solutions could either be to...
- distribute the slf4j-api-1.x.x.jar along with the Log4J2 distribution (perhaps as log4j-slf4j-api-2.0.jar)
- package the necessary SLF4J API classes directly into the log4j-slf4j-impl-2.0.jar) (renaming that one then simply to log4j-slf4j-2.0.jar)
The second solution is how SLF4J handles things, how the description page above describes things and how the Commons Logging binding/bridge is supposed to work (i.e. log4j-jcl-2.0.jar) (see LOG4J2-722)
