How can I exclude sub-dependencies from unmanaged dependencies?

问题

I know in sbt you can do something like this to exclude specific sub-dependencies of dependencies for some lib your project uses:

  val kafka        = "org.apache.kafka"    %  "kafka-clients"        % "0.9.0.1" excludeAll(
    ExclusionRule(organization = "com.sun.jdmk"),
    ExclusionRule(organization = "com.sun.jmx")
  )

How can I do this for an unmanaged jar? I put an unmanaged library jar 'something.jar' in my project's lib directory but sbt is giving me errors for some dependencies of something.jar that I don't care about. How can I exclude these?
