Errors with scalatest 2.1.RC1 and scalacheck 1.11.3

[Patrick Mahoney]

Hello Bill,

I upped the version numbers on scalatest to the recent RC and scalacheck to the most recent 1.11.3.

I then run a clean compile. Many of these stacktraces that show up in our test stream:

[error] Uncaught exception when running com.company.lang.Test: java.lang.NoClassDefFoundError: Could not initialize class com.company.lang.tools.ClassName$

We also get many traces like the following. I'm thinking that it is a scalatest / scalacheck incompatibility.

Just wanted to make sure you had feedback re: the RC.

Thanks for your work Bill,

Hi Patrick,

I'm not sure what the first issue is, but the second one is likely that you need to upgrade ScalaCheck to 1.11. We also upgraded versions of other optional dependencies. They are all defined in the pom here:

https://oss.sonatype.org/content/groups/public/org/scalatest/scalatest_2.10/2.1.RC1/scalatest_2.10-2.1.RC1.pom

If you're using scalaz, though, then that's going to be a problem because they haven't yet released a version with ScalaCheck 1.11. I was waiting for that but got tired of waiting, because it was annoying users who didn't use scalaz and wasting their time. Let me know if you still get the first issue. I'm guessing com.company is a cleaned up name for your one of your own internal packages?

Bill
