Perché NoClassDefFoundError viene generato con "run" ma funziona bene con "dist"?

Question

Prima di porre la domanda avevo letto la domanda Play framework java.lang.NoClassDefFoundError only in dev mode e diversi altri post. Non mi hanno aiutato a risolvere il mio problema.

Ho creato un progetto utilizzando Typesafe Activator 1.2.12 e play-scala modello. Ho anche impiegato Slick 2.1.0.

Voglio incorporare il database h2 con estensione h2gis in gioco.

Quando il progetto Play è iniziato ad usare activator run, il seguente Execution exception viene visualizzata nel browser:

La seguente analisi dello stack è sulla console:

18013 [play-akka.actor.default-dispatcher-3] ERROR application -

Tuttavia, se Eseguo activator dist ed eseguo l'applicazione funziona bene (!)

Il file jar per h2 è in lib e in riferimento a sbt e senza utilizzare h2gis, non si verifica alcun errore.

Il codice sorgente del progetto è su GitHub come progetto weird-error. Utilizzare il progetto per affrontare l'errore.

Aggiornamento:

Ecco l'output di analisi con il comando ./activator run -J-XX:+TraceClassLoading incollo solo una parte di esso, sembra CoordinateArraySequence sollevare l'eccezione.

Provate ad aggiungere queste dipendenze al file build.sbt invece di mettere i file all'interno della lib.

"com.typesafe.slick" %% "slick" % "2.1.0", 
"org.orbisgis" % "h2gis" % "1.1.0", 
"com.vividsolutions" % "jts" % "1.13" 

in modalità dev, il gioco SBT sarebbe utilizzare più classloader per sostenere hot-ricaricando mentre dopo dist ci sarà solo un programma di caricamento classe per gestire il vostro progetto. Detto questo, mettere tutto nello stesso posto potrebbe risolvere il tuo problema.
