qualcuno mi può aiutare su questo? ho bisogno di pubblicare la mia app. la soluzione sarà apprezzata. grazie in anticipo.

Answer 1

Basato sul post qui: https://plus.google.com/112998433182673852267/posts/ApBBBjv9szw

Che cosa sta realmente accadendo è che la classe "fromstring" mancante è un'annotazione che non è effettivamente presente in un file di classe in Joda-tempo-2.0.jar. Esiste un reclamo (http://www.scala-lang.org/node/10575) per cui un file di classe di annotazione mancante non dovrebbe influire sulla compilazione, il che sembra corretto, ma non so dove questo sia formalmente dichiarato.

È necessario aggiungere http://joda-convert.sourceforge.net/ al percorso di generazione del progetto.

Answer 2

Se non sono necessarie le classi mancanti, è possibile eliminare gli avvertimenti:

-dontwarn org.joda.convert.**
