logger in custom module of widfly is not working - module

Question

I am working on web application project in wildfly. I have a web-application project which has dependency on authentication jar file. Instead of placing the authentication jar file in WEB-INF/lib, the authentication jar file placed in wildfly custom module says "com.example.authentication"
The authentication project does have log4j propery file for the logger, however, log4j jar file has been invoked common module says "com.example.logger" having log4j.jar file.
I expect the logger to be working in authentication project but the logger is not working for authentication module. NO errors or warnings on this.
Webapplication - WEB-INF/jboss-deployment-structure.xml
<jboss-deployment-structure>
<deployment>
<module name="com.example.authentication"/>
</deployment>
</jboss-deployment-structure>
com.example.authentication - module.xml
<module xmlns="urn:jboss:module:1:3" name="com.example.authentication">
<resources>
<resource-root path="authentication.jar"
</resources>
<dependencies>
<module name="com.example.logger" export="true"/>
</dependencies>
</module>
com.example.logger - module.xml
