Steps

error log Exception in thread "main" org.scalafmt.Error$PreciseIncomplete: <input>:16: error: Unable to format file due to bug in scalafmt ) on save or run scalafmt in sbt.

origin code:

class A {
  def foo: B =
    a.b() { c =>
        val d = c.add(
          D[E](
            1, {
              case conditionNameShouldLongEnough =>
                foo1(objectNameShouldLongEnough, objectNameShouldLongEnough)
                0
              case conditionNameShouldLongEnough =>
                foo1(objectNameShouldLongEnough, objectNameShouldLongEnough)
                1
            }
          )
        )
      }
      .f("f")
}

Here is my demo to call internal api of scalafmt, it is proved that this bug is introduced by configuring optIn.configStyleArguments to false. style Intellij include this configuration, so using config file I paste above also has this issue.

import org.scalafmt.Scalafmt
import org.scalafmt.config.ScalafmtConfig.default
import org.scalafmt.config.{ContinuationIndent, Docstrings, ScalafmtConfig}

object Test extends App {
  val code =
    """
      |class A {
      |  def foo: B =
      |    a.b() { c =>
      |        val d = c.add(
      |          D[E](
      |            1, {
      |              case conditionNameShouldLongEnough =>
      |                foo1(objectNameShouldLongEnough, objectNameShouldLongEnough)
      |                0
      |              case conditionNameShouldLongEnough =>
      |                foo1(objectNameShouldLongEnough, objectNameShouldLongEnough)
      |                1
      |            }
      |          )
      |        )
      |      }
      |      .f("f")
      |}
    """.stripMargin
  println(code)
  val config = ScalafmtConfig.default.copy(

    docstrings = Docstrings.ScalaDoc,
    maxColumn = 120,
    continuationIndent = ContinuationIndent(2, 2),
    optIn = default.optIn.copy(

  val formattedCode = Scalafmt.format(code,style = config,range = Set.empty).get
  println(formattedCode)
