with latest 2.12.1 nightly, "class scala.IndexOutOfBoundsException not found" #88

Closed SethTisue closed 7 years ago

SethTisue commented 7 years ago

this was found by the Scala 2.12 community build, but can be reproduced independently, on the 2.12.0 branch of paradise, with:

++2.12.1-de003f7-nightly
set every scalaBinaryVersion := "2.12"
tests/test

resulting in a lot of repeated errors like:

@xeno-by are you available to look at this? if this is an issue for Scala 2.12.1, we'll need to know soon. also, this is making every 2.12.x Scala community build fail.

xeno-by commented 7 years ago

I will do that tomorrow. Been travelling the last week.

What resolver should I use? 

resolvers += "release-temp" at "https://scala-ci.typesafe.com/artifactory/scala-release-temp/"

I noticed I was answering this question a lot, so: http://stackoverflow.com/questions/40622878/how-do-i-tell-sbt-to-use-a-nightly-build-of-scala-2-11-or-2-12

xeno-by commented 7 years ago

Can reproduce. Will investigate now.

xeno-by commented 7 years ago

It turns out that paradise itself is fine.

It's the code of the test macro that changed behavior. After I fixed the test, everything became green again. See https://github.com/scalamacros/paradise/commit/a976e750e15078fb19f0007b1d1c64e6acb6da87 for more information.
