Wie kann ich überprüfen, welche Linie verursacht es?

SBT kompilieren dauert 361 s und es wirft:

Sie sollten Remote Debugging verwenden können. Erstellen Sie eine Remote-Debugger-Konfiguration in Ihrer bevorzugten IDE (http://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Fconcepts%2Fcremdbug.htm für Eclipse, https://www.jetbrains.com/help/idea/2016.2/run-debug-configuration-remote.html für IDEA) mit scala-compiler-<your-scala-version>-sources.jar und scala-reflect-<your-scala-version>-sources.jar. In

set javaOptions in compiler := List("-Xdebug", "-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8002")

(entnommen aus https://groups.google.com/d/msg/scala-user/XI_Ujax_Oq8/o2Hrs-KjAgAJ) in Ihrem SBT bauen. Wenn Sie dann sbt compile ausführen, wird gewartet, bis Sie eine Debugsitzung starten. Setzen Sie einen Ausnahme-Breakpoint für StackOverflowError und Sie sollten das Problem lokalisieren (nicht unbedingt auf eine bestimmte Zeile).
