I'm developing a Play! application using sbt 1.2.8 scala 2.12.10 I'm trying to upgrade Play from 2.7.4 to 2.8.1, but during compilation I get [error] Input length = 1. No stack trace, nothing. It was compiling up until 2.7.4.
I've found java.nio.charset.MalformedInputException: Input length = 1
result with Google, but I can't imagine how that could be relevant to Play! version bump.
The scalac options:
"-deprecation","-explaintypes", "-feature", "-unchecked", "-language:_", "-Xlint",
"-Ywarn-dead-code", "-Ywarn-extra-implicit", "-Ywarn-inaccessible",
"-Ywarn-infer-any", "-Ywarn-nullary-override", "-Ywarn-nullary-unit",
"-Ywarn-unused:implicits", "-Ywarn-unused:locals", "-Ywarn-unused:patvars",
"-Ywarn-unused:privates"
Any clues would be appreciated
