Hi @alikemalocalan, can you provide a little more context on your setup prior to running the sbt command?

Maybe Problem would be adding jackson into every sub project dependencies. why did com.fasterxml.jackson.core had added every finagle util dependencies. maybe it would be enough just to put it in the com.twitter:util-core ?
