How to Set `-Ypatmat-exhaust-depth off` scalac flag?

[Kevin Meredith]

Given the following compile-time error:

Exhaustivity analysis reached max recursion depth, not all missing cases are reported.

[error] (Please try with scalac -Ypatmat-exhaust-depth 40 or -Ypatmat-exhaust-depth off.)

So, heeding that warning, I updated my `build.sbt`:

scalacOptions ++= Seq(

  "-Ypatmat-exhaust-depth off"

)

Then, I typed `reload`, and then `compile`, but got this error:

[error] bad option: '-Ypatmat-exhaust-depth off'

How can I properly add this scalac option?

[Seth Tisue]

it's two arguments, so:

    scalacOptions ++= Seq("-Ypatmat-exhaust-depth", "off")
