Maven: Unused dependencies and test-only dependencies
baulea opened this issue · 2 comments

mvn dependency:analyze lists some used undeclared / unused declared / non-test scoped test only dependencies.
In a first step I would like to
- remove unused declared
- change non-test scoped test only dependencies to scope test
I would be glad if you assign this issue to me.

After manual verification I found the following items to reduce complexity:
core/pom.xml:
- set test scope for org.jukito:jukito
- remove com.fasterxml.jackson.datatype:jackson-datatype-jdk8, because it is unused
- remove direct dependency ch.qos.logback:logback-core, because it is a direct dependency from ch.qos.logback:logback-classic and not used in the core project directly
kafka-testing/pom.xml
- remove com.google.protobuf:protobuf-java-util, because it is unused
- remove dependency for com.github.os72:protoc-jar. It is only used as and not additionally as dependency
