"val lines = comments.flatMap(_.lines)" in FieldT.scala: type mismatch

[eLvErDe]

Hello,

Most of the version fails to build with the following error:

[error] /home/acecile/packaging/marathon/marathon-1.9.109/build/type-generator/src/main/scala/mesosphere/raml/ir/FieldT.scala:76:36: type mismatch;
[error]  found   : java.util.stream.Stream[String]
[error]  required: scala.collection.GenTraversableOnce[?]
[error]     val lines = comments.flatMap(_.lines)

Best regards, Adam.

I can remember having also problems building on centos7. I decided to extract it from the docker images.
