@romain-grecourt could you please confirm if it is OK to add versions for example dependencies, or if these should be version managed in dependencies/pom.xml.

Need to double check with Joe, we should add them to dependencies/pom.xml only if we have an existing approval for them. At the very least we should declare properties for these versions to make it look cleaner.

Hello @tvallin, there were some changes related to presence of slf4j libraries, and I think that is why the merge branch is failing. could you kindly fix this, I will review/merge as soon as the pipelines pass

This requires a bit more work. working on this myself

@barchetta I have added a logback core dependency management to dependencies. This is already part of logback-classic (a transitive dependency).
This version management is needed for Cassandra, which depends on both of these libraries explicitly (and we would end up with different versions of them)
