As we said previously when the the question arose again there would be a 
discussion. You may not remember, but I expect there to be a discussion.

I have built a graph of Maven Central to analyze the rank (count of all 
incoming edges) for Log4J2 and Logback and it is clear from those numbers that 
everyone has gone from Log4J to Logback. What has happened, I believe from the 
numbers, is that the community followed the founder of the project and not the 
owner project in pretty much the exact same way users went with Jenkins and not 
Hudson. Anyone is happy to take the graph and verify this themselves, or 
generate their own data from the machine that is housing the copy of Maven 
Central at Google.

Additionally Igor has an implementation for logging during concurrent builds 
based on Logback that I would really like to use, and the color logging is also 
easy with Logback. I do not want to use something that the community at large 
has not adopted.

Again, anyone is welcome to the code and/or the data if they want to verify 
this themselves.

I also am not interested in a debate so if we disagree then just leave the 
simple implementation in place. I’m not philosophically motivated much here in 
these discussions but I’m vehemently opposed to integrating Log4J2.

Just because only 2.4 was available when I updated this feature branch

Hi Arnaud,

Thank you for the update.

Why not update the Log4j 2 dep from 2.4 to 2.5?

Hi Gary,

I fixed this in the branch :
https://github.com/apache/maven/commits/slf4j-log4j2.4
The fix is in




maven-embedder/src/main/resources/META-INF/maven/slf4j-configuration.properties

(




https://github.com/apache/maven/commit/8cddea291c279130d437bcdf3337f16296558530

It is the update I did after my old blog post :

Hi All,

Happy Holidays.

Can the next version of Maven be rid of this warning:

[WARN] The SLF4J binding actually used is not supported by Maven:
org.apache.logging.slf4j.Log4jLoggerFactory
[WARN] Maven supported bindings are:
[WARN] (from





jar:file:/E:/Java/apache-maven-3.3.9/bin/../lib/maven-embedder-3.3.9.jar!/META-INF/maven/slf4j-configuration.properties)

- ch.qos.logback.classic.LoggerContext
- org.slf4j.helpers.Log4jLoggerFactory
- org.slf4j.impl.SimpleLoggerFactory

Is there a step I am missing to use Log4j 2 cleanly? My steps are
