I'm using the maven shade plugin with apache-log4j-extras-1.2.17 and log4j-1.2.17. That plugin takes the project artifacts and all its dependencies and puts them in a single jar. During compilation, the plugin states:
[WARNING] apache-log4j-extras-1.2.17.jar, log4j-1.2.17.jar define 126 overlappping classes: [WARNING] - org.apache.log4j.xml.DOMConfigurator$2 [WARNING] - org.apache.log4j.xml.DOMConfigurator$5 [WARNING] - org.apache.log4j.NDC$DiagnosticContext [WARNING] - org.apache.log4j.spi.AppenderAttachable [WARNING] - org.apache.log4j.spi.ErrorHandler [WARNING] - org.apache.log4j.spi.RootCategory [WARNING] - org.apache.log4j.pattern.PatternConverter [WARNING] - org.apache.log4j.TTCCLayout [WARNING] - org.apache.log4j.RollingCalendar [WARNING] - org.apache.log4j.spi.Configurator [WARNING] - 116 more... [WARNING] maven-shade-plugin has detected that some .class files [WARNING] are present in two or more JARs. When this happens, only [WARNING] one single version of the class is copied in the uberjar. [WARNING] Usually this is not harmful and you can skeep these [WARNING] warnings, otherwise try to manually exclude artifacts [WARNING] based on mvn dependency:tree -Ddetail=true and the above [WARNING] output [WARNING] See http://docs.codehaus.org/display/MAVENUSER/Shade+Plugin If I exclude apache-log4j-extras-1.2.17, then my code complains about not having the updated RollingAppender. If I exclude log4j-1.2.17, then my code complains that it can't find RendererMap. Any ideas on how to get this code to work properly with the overlapping classes? Thanks, Chris
