supply a classpath for xmlbeans plugin

Question

In a maven project I am using xmlbeans plugin to generate access functions to xml schema based xml files.

xmlbeans needs log4j-core on the classpath for logging, which it misses in the generate-sources phase.

It issues the error

ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...

How can I put the regarding jar file on the classpath while maven is generating source code?

Here is the reduced pom.xml:
