SLF4j actual binding gets unset when importing dgraph4j

[vxe]

https://github.com/dgraph-io/dgraph4j

Essentially without this project in deps.edn:

SLF4J: Actual binding is of type [com.github.fzakaria.slf4j.timbre.TimbreLoggerFactory]

adding it results in

 SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory]

using these dependencies

        io.dgraph/dgraph4j {:mvn/version "2.0.2"}
        com.taoensso/timbre {:mvn/version "4.10.0"}
        com.fzakaria/slf4j-timbre {:mvn/version "0.3.19"}
        org.slf4j/slf4j-api {:mvn/version "1.7.21"}

Are you able to reproduce and/or know the cause of this?

This is a bug in dgraph4j, which lists org.slf4j/slf4j-simple as a compile-time dependency in the default scope. Libraries should not propagate specific slf4j bindings to dependent projects - see the slf4j FAQ.

Please file a bug report with dgraph4j, telling them to scope their dependency on org.slf4j/slf4j-simple correctly to stop it propagating to other people's projects. You could link them to this comment.

A temporary workaround for you, until dgraph4j fix their project, is to manually exclude it from your project dependencies:

• deps.edn:
  io.dgraph/dgraph4j {:mvn/version "2.0.2" :exclusions [org.slf4j/slf4j-simple]}
• lein project.clj:
  [io.dgraph/dgraph4j "2.0.2" :exclusions [org.slf4j/slf4j-simple]]

Please confirm this fixes your problem. Thanks

work around worked, and bug report filed. Great work on this project!
