У меня были некоторые проблемы с компиляцией моего игрового каркасного приложения. Иногда приложение работает нормально, но в большинстве случаев эти проблемы возникают с помощью инструментов sbt и activator. Вот пример компиляции моего приложения с помощью sbt:

[error] 12 errors
[error] (compile:compile) javac returned nonzero exit code
[error] Total time: 16 s, completed Oct 31, 2014 11:18:25 AM

В других случаях я получу эту ошибку с помощью sbt clean compile:

[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

Затем я выхожу из sbt, затем снова запускаю sbt clean compile, и все, кажется, компилируется нормально. Я даже запустил активатор run и все отлично компилируется, но ни один из маршрутов не распознается:

# Home page
GET     /               controllers.Application.index

GET     /login          controllers.Application.login

И тогда я получу ошибки компиляции с активатором run:

Я также получил несколько разных ошибок, но для краткости я не буду их здесь писать. Я пробовал предложения по удалению папок .sbt и .ivy2 / cache, но это не решило проблему.

Так что мне делать, чтобы мое игровое приложение компилировалось и работало без, казалось бы, недетерминированных ошибок?
