cmd1.sc:10: Symbol 'term akka.stream.scaladsl' is missing from the classpath.
This symbol is required by 'class akka.http.scaladsl.model.SslSessionInfo'.
Make sure that term scaladsl is in your classpath and check for conflicting dependencies with `-Ylog-classpath`.
A full rebuild may help if 'SslSessionInfo.class' was compiled against an incompatible version of akka.stream.
