I only tried to resolve the library’s dependencies on my machine but it was fine

@martinklepsch yeah the syndrome looks similar. jackdaw also uses a custom maven repo for Confluent’s libraries (https://github.com/FundingCircle/jackdaw/blob/master/project.clj#L43)

I’m not sure if I committed this but I tried adding more repos to :mvn/repos (deps.clj I think). If you want you could give that a shot
