title: How to config slf4j+logback in a multi-module Maven project?
body: <p>My Maven project has about seven sub-modules. Six of them packages as JARs and one as WAR. </p>
  
  <p>Should I create individual logback.xml config in each module? Or should I have a "common" module that all other modules depend on, and put one single logback.xml in there? Are there any other options?</p>
  
  <p>Thanks.</p>
