Scala: Wtyczka SBT Eclipse nie buduje Breeze from scalanlp.org - eclipse-plugin, sbt, scala-ide, scala-breeze

Jestem nowy w Breeze (http://www.scalanlp.org/) i ogólnie Scala. Proszę o pomoc w generowaniu Projekt Eclipse dla Breeze z sbt. Mam zainstalowaną wtyczkę Eclipse do sbt. Kiedy próbuję sbt eclipse kończy się niepowodzeniem z następującymi błędami. Co jest źle? Dzięki!

Odpowiedzi:

To znany błąd w sbteclipse: https://github.com/typesafehub/sbteclipse/issues/128

Możesz spróbować skomentować projekt „doc” w definicji Project.scala i sprawdzić, czy to pomoże. W przeciwnym razie myślę, że jest to błąd w sbteclipse, który należy rozwiązać w pierwszej kolejności.
