expected a field symbol, you provided a method symbol A typical cause of this problem is using a field accessor symbol instead of a field symbol. To obtain a field symbol append nme.LOCAL_SUFFIX_STRING to the name of the field, when searching for a member with Type.members or Type.declarations. This is a temporary inconvenience that will be resolved before 2.10.0-final. More information can be found here: https://issues.scala-lang.org/browse/SI-5895.
