after upgrading to 1.2.6: `A fatal error happened in `SameAPI`: different extra api hashes for no traits!`

See original GitHub issue

steps

Have multi-module project Change SBT version to 1.2.6

problem

Change SBT version and compile project. Get exception like:

...

After next recompilation, project managed to get built.

expectation

Upgrade of patch versions should be simple, but if there are some internal format incompatibilities, then SBT must inform user to discard previous compilation results.

notes

There are several such places where SBT fails to compile. The exception happens for case classes like:

    final case class ClassName(field: OtherCaseClass)

    object SetupResponse {
      implicit val ClassNameFormat: OFormat[ClassName] = Json.format
    }

@jvican it seems that there’s more unforeseen issues with the API check you added in zinc. Any idea why ? What about just disabling the assertion ?
