Hello,
we migrated our servlet based application to dropwizard and would like to thank the community for this project and ongoing progress! I probably made something stupid in the maven config or something. Running the shaded jar works fine, but when executing integration tests I get this warning: SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/graphhopper/web/target/graphhopper-web-0.11-SNAPSHOT.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/home/user/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder] INFO [2018-04-08 18:44:27,653] org.eclipse.jetty.util.log: Logging initialized @1090ms to org.eclipse.jetty.util.log.Slf4jLog Where graphhopper-web-0.11-SNAPSHOT.jar is the shaded jar with dropwizard (with logback). This usually means <https://stackoverflow.com/q/12494420/194609> that more than one slf4j binding is on the classpath but I could reject this theory and only slf4j-api is there, plus the logback dependency for dropwizard. I also have analyzed the dependency graph with Netbeans and mvn dependency:tree -Dverbose -Dincludes=org.slf4j (see output here <https://gist.github.com/karussell/f0b1bb284df5b0041c47ca5b980866d9>) but couldn't find something problematic. *Can it be that the shaded jar (with logback) is somehow put into the classpath with the other jars (including logback) for mvn clean install? How could I avoid this?* Reproduce it via: git clone https://github.com/graphhopper/graphhopper cd web mvn clean install See this issue <https://github.com/graphhopper/graphhopper/issues/1328> and this stackoverflow question <https://stackoverflow.com/q/49782932/194609> with a working answer but one that I do not fully understand.
