Scala stack traces are complex, mostly because of the way anonymous functions are translated to bytecode. Here's a example:
java.lang.IllegalStateException
at com.company.IdentityVerifier$$anonfun$go$2$$anonfun$apply$2.apply$mcII$sp(IdentityVerifier.scala:19)
at com.company.IdentityVerifier$$anonfun$go$2$$anonfun$apply$2.apply(IdentityVerifier.scala:17)
at com.company.IdentityVerifier$$anonfun$go$2$$anonfun$apply$2.apply(IdentityVerifier.scala:17)
at scala.collection.TraversableLike$$anonfun$map$1.apply(TraversableLike.scala:244)
at scala.collection.TraversableLike$$anonfun$map$1.apply(TraversableLike.scala:244)
at scala.collection.immutable.List.foreach(List.scala:318)
at scala.collection.TraversableLike$class.map(TraversableLike.scala:244)
at scala.collection.AbstractTraversable.map(Traversable.scala:105)
at com.company.IdentityVerifier$$anonfun$go$2.apply(IdentityVerifier.scala:17)
at com.company.IdentityVerifier$$anonfun$go$2.apply(IdentityVerifier.scala:16)
at scala.collection.TraversableLike$$anonfun$flatMap$1.apply(TraversableLike.scala:251)
at scala.collection.TraversableLike$$anonfun$flatMap$1.apply(TraversableLike.scala:251)
at scala.collection.immutable.List.foreach(List.scala:318)
at scala.collection.TraversableLike$class.flatMap(TraversableLike.scala:251)
at scala.collection.AbstractTraversable.flatMap(Traversable.scala:105)
at com.company.IdentityVerifier$.go(IdentityVerifier.scala:16)
at com.company.UserMap.setLastUserId(UserMap.scala:12)
at com.company.UserConsumer.setCurrentUser(UserConsumer.java:69)
at com.company.UserConsumer.consume(UserConsumer.java:64)
at com.company.UserProducer.execute(UserProducer.java:19)
at com.company.UserCreator.execute(UserCreator.java:18)
at com.company.UserCreatorMain$1.run(UserCreatorMain.java:37)
at com.company.UserCreatorMain.main(UserCreatorMain.java:51)
I've found stackifier (it's their example), but it's a pain to keep pasting stack traces to a webpage. Is there a way to print "better" stack traces automatically?
