[GitHub] [shardingsphere] ziliangzeng opened a new issue #13307: Referencing sharding-jdbc and log4j-over-slf4j at the same time will cause conflicts. What is the specific reason?
ziliangzeng opened a new issue #13307:
URL: https://github.com/apache/shardingsphere/issues/13307
## Question
I try to introduce sharding-jdbc into the old project. The project used org.slf4j:log4j-over-slf4j:1.7.26 before, which would cause conflicts to fail. Try to check the dependency package of sharding-jdbc and find that org.slf4j:log4j-over-slf4j is not referenced. Will different dependencies affect each other? Is there any way to deal with it? Thank you.
## version
org.apache.shardingsphere:shardingsphere-jdbc-core:5.0.0-beta
org.slf4j:log4j-over-slf4j:1.7.26

By using the method of elimination, I found that `<exclusion>
<groupId>org.apache.shardingsphere</groupId>
<artifactId>shardingsphere-db-discovery-core</artifactId>
</exclusion>`
is The main cause of conflict
What kind of problems will it cause if I exclude this dependency? What is this module used for?
