             Summary: SLF4J API classes missing from distribution
                 Key: LOG4J2-723
                 URL: https://issues.apache.org/jira/browse/LOG4J2-723
             Project: Log4j 2
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Holger Stenzhorn


The page [Log4j 2 SLF4J 
Binding|http://logging.apache.org/log4j/2.x/log4j-slf4j-impl/index.html] 
mentions under *Usage* that... 
bq. 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...
bq. 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 
aboves describes things and how the Commons Logging binding/bridge is supposed 
to work (i.e. {{log4j-jcl-2.0.jar}}) (see LOG4J2-722)
