Arnaud HERITIER commented on MNG-5842:
--------------------------------------
Reported as MNG-5845, and MNG-5787. The problem comes from the fact that we are
exporting the slf4j-api artefact, thus plugins cannot use their own version but
we forgot to export the content of the package org/slf4j/helpers. Thus the
`java.lang.ClassNotFoundException: org.slf4j.helpers.MessageFormatter`
> java.lang.NoClassDefFoundError: org/slf4j/helpers/MessageFormatter with jetty
> plugin

> Key: MNG-5842
> URL: https://issues.apache.org/jira/browse/MNG-5842
> Project: Maven
> Issue Type: Bug
> Components: Class Loading
> Affects Versions: 3.3.1, 3.3.3
> Reporter: Jean-Christophe Gay
>
> When Maven is used with a different SLF4J implementation than slf4j-simple
> (in my case logback to have colored logs), running jetty-maven-plugin fails.

> I have tried running jetty with a patched maven-core.jar (adding
