Anyone any thoughts? Actually we are thinking of migrating to log back from log4j. So we want to try logback in one module first. We have quite a few custom Appenders and layouts in log4j. So we want to do the migration module by module. 

But the current issue that I am getting is preventing me from using logback in one module and log4j in other modules in the multi module maven project.

Correct restapilayer.logback.xml
