Logging Issues / Standard Maven Dependencies
Jamie Lawson <jamier...@...>
I've been using the nasty method of building JanusGraph and copying all of jars from the janusgraph/lib directory into the myproject/lib directory. That is, myproject has more than 200 unmanaged dependencies. This has some obvious issues. One is that SBT gives me this unpleasant error message:
[error] SLF4J: Class path contains multiple SLF4J bindings.
[error] SLF4J: Found binding in [jar:file:/home/jlawson/workspace/myproject/lib/slf4j-log4j12-1.7.12.jar!/org/slf4j/impl/StaticLoggerBinder.class]
[error] SLF4J: Found binding in [jar:file:/home/jlawson/workspace/myproject/lib/logback-classic-1.1.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
[error] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
[error] SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
This seems, with high assurance, to be a consequence of the unmanaged dependencies. It also seems that when I remove the slf4j jar file from the JanusGraph stuff, it changes the behavior of the logger dramatically. There is a whole bunch of other log output that I don't want or need to see. So when will I just be able to include a line in my SBT file that says something like:
libraryDependencies += "org.janusgraph" % "janusgraph" % "0.1.0"
And let SBT deal with all of the cross-dependencies?
Short of that, how do I get SLF4J to play nicely?
