If I rm the file and compile, it works fine, until the next compile.

Sometimes it emits a very long traceback, sometimes not, but the error message is the same.

If it's absolutely necessary, I can share the source code of the file under question. It's basically just ~30 or so definitions of type class instances of play-json's Format[T]/Reads[T]/Writes[T] + a few scalaz's Monoid[T] instances.

Short one:

[error] missing or invalid dependency detected while loading class file 'Mapping.class'.
[error] Could not access type $anon in value com.soda.profile.analysis.evidence.TwitterEvidence.twEvIO,
[error] because it (or its dependencies) are missing. Check your build definition for
[error] missing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic classpath.)
[error] A full rebuild may help if 'Mapping.class' was compiled against an incompatible version of com.soda.profile.analysis.evidence.TwitterEvidence.twEvIO.
java.lang.ClassCastException
[error] error while loading Mapping, class file '/Users/erik/code/soda-profile/core/target/scala-2.11/classes/com/soda/profile/models/Mapping.class' is broken
[error] (class java.lang.RuntimeException/error reading Scala signature of Mapping.class: null)

Loading the Queries object which extends the above problematic Mapping trait from sbt console yields the following. I'm posting it here since the error message is the same so it's probably relevant.

All in all, is this a SBT bug or a Scala/scalac one?

Looks like scalac's classfile parser, by the stack trace. sbt could still have somethign to do with it, but I'd check to see if it's reproducable sans-sbt

@eallik Any update on this? Were you able to reproduce the issue without using sbt?

I'm getting the same issue. Error:

If anyone could offer reproducible test case that would move this issue forward.

I am closing this due to inactivity, but if this is still relevant let us know with more details (reproduction steps etc).
