    [ https://issues.apache.org/jira/browse/LOG4J2-3570?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17578540#comment-17578540 ] 

Ralph Goers commented on LOG4J2-3570:
-------------------------------------

# apache-log4j-extras was for log4j 1. It will not work with Log4j2 until you include log4j-1.2-api which you do not show.
# log4j-core requires log4j-api. You don't seem to specify a dependency on it so it seems it is not picking up 2.18.0, in which ServiceLoaderUtil was added.

> Hello,
> Earlier I am using the below libraries in the Java Gradle project, and it works fine:
> {color:#4c9aff}implementation 'org.slf4j:slf4j-api:1.7.36'{color}
> {color:#4c9aff}implementation 'org.slf4j:slf4j-log4j12:1.7.36'{color}
> {color:#4c9aff}implementation 'org.apache.logging.log4j:log4j-core:2.17.2'{color}
> {color:#4c9aff}implementation 'log4j:apache-log4j-extras:1.3.1-mapr'{color}
> But as soon as I upgrade to{color:#4c9aff} 'org.apache.logging.log4j:log4j-core:2.18.0'{color}, I am starting to get error.
>  
> Thank you
