Probleme beim Kompilieren der Spielanwendung
Beim Kompilieren meiner Play Framework-Anwendung sind einige Probleme aufgetreten. Manchmal läuft die Anwendung einwandfrei, aber meistens treten diese Probleme sowohl mit dem sbt- als auch mit dem activator-Tool auf. Hier ist ein Beispiel für das Kompilieren meiner Anwendung mit sbt:

[error] Total time: 16 s, completed Oct 31, 2014 11:18:25 AM
Other Mal werde ich diesen Fehler mit sbt clean compile bekommen:
[info] Compiling 15 Scala sources and 1 Java source to C:\Server\trunk\target\scala-2.11\classes...
[trace] Stack trace suppressed: run last compile:compile for the full output.
[error] (compile:compile) java.lang.NoClassDefFoundError: Lcontrollers/ReverseAssets;
[error] Total time: 45 s, completed Oct 31, 2014 11:45:49 AM
Dann beende ich sbt und führe sbt clean compile erneut aus und alles scheint gut zu kompilieren. Ich werde sogar Activator Run ausführen und alles wird gut kompiliert, aber keine der Routen wird erkannt:
# Home page
GET / controllers.Application.index
GET /login controllers.Application.login
Und dann bekomme ich beim Kompilieren mit Activator Run Fehler:
[info] Compiling 15 Scala sources and 1 Java source to C:\Server\trunk\target\scala-2.11\classes...
[error] C:\Server\trunk\target\scala-2.11\src_managed\main\controllers\routes.java:13: error: cannot find symbol

Dann starte ich Activator Clean Run und bekomme einen ganz anderen Fehler:

Ich habe auch ein paar verschiedene Fehler bekommen, aber der Kürze halber werde ich sie hier nicht schreiben. Ich habe versucht, die Ordner .sbt und .ivy2 / cache zu löschen, aber das hat das Problem nicht gelöst.
So was mache ich, damit meine Spielanwendung ohne scheinbar nicht deterministische Fehler kompiliert und ausgeführt wird?
