Hendy Irawan commented on JENA-583: ----------------------------------- +1 for this :) Excluding these dependencies from app is a good workaround since it's low effort anyway. At first I wanted to propose using Maven {{<profile>}} to separate the command line dependencies from normal dependencies, but that's not such a good idea, the better way would be separation of modules at Jena level. At least now I know why log4j is depended by Jena. :) > Get rid of log4j dependency in jena-core > ---------------------------------------- > > Key: JENA-583 > URL: https://issues.apache.org/jira/browse/JENA-583 > Project: Apache Jena > Issue Type: Improvement > Components: Jena > Affects Versions: Jena 2.11.0 > Reporter: Francis De Brabandere > Labels: logging > > Apache jena core seems to pull in log4j and slf4j-log4j12, since you use > slf4j I would suppose I can plug in my own logging backend. If you have a > hard dependency on log4j at least make it optional and don't force it in the > core jena components. > Ultimately this avoids these kinds of issues: > SLF4J: Class path contains multiple SLF4J bindings. > SLF4J: Found binding in > [jar:file:.../target/universal/stage/lib/ch.qos.logback.logback-classic-1.0.13.jar!/org/slf4j/impl/StaticLoggerBinder.class] > SLF4J: Found binding in > [jar:file:.../target/universal/stage/lib/org.slf4j.slf4j-log4j12-1.6.4.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] -- This message was sent by Atlassian JIRA (v6.2#6252)
