Plugin with Scala 2.11 and scalafmt 1.1.0 cause NoSuchMethodError

See original GitHub issue

We use Scala 2.11.11 plugins.sbt:

addSbtPlugin("com.lucidchart" % "sbt-scalafmt" % "1.10")

build.sbt

scalafmtVersion in ThisBuild := "1.1.0"

sbt scalafmt throws

java.lang.NoSuchMethodError: scala.Product.$init$(Lscala/Product;)V
	at scala.meta.inputs.Input$String.<init>(Input.scala:23)
	at scala.meta.inputs.Input$String$.apply(Input.scala:23)
	at org.scalafmt.config.Config$.fromHoconString(Config.scala:55)
	at com.lucidchart.scalafmt.impl.ScalafmtFactory.fromConfig(ScalafmtFactory.scala:11)
	at com.lucidchart.scalafmt.impl.ScalafmtFactory.fromConfig(ScalafmtFactory.scala:9)
	at com.lucidchart.sbt.scalafmt.ScalafmtCorePlugin$autoImport$$anonfun$18.apply(ScalafmtCorePlugin.scala:143)
	at com.lucidchart.sbt.scalafmt.ScalafmtCorePlugin$autoImport$$anonfun$18.apply(ScalafmtCorePlugin.scala:134)
...

My guess is that this is because scalafmt-impl 1.10-1.0 has not been published for Scala 2.11 so it tries to use scalafmt-impl_2.12 in a Scala 2.11 project.

@dragisak I also solved the error by manually specifying the scalafmtVersion, maybe the default value for the version is a bit off?

@dragisak I was able to resolve that error by removing scalafmtVersion := "1.0.0-RC4" from the build.sbt. I am not sure about the reason though.
