java.lang.NoClassDefFoundError: arrow/core/NonFatalOrThrowKt

[JesusMcCloud]

We're having a really weird issue, we don't even know how to debug.

Our KmmResult library uses Arrow for its nonFatalOrThrow function and we use it in all of our KMP projects, so we can export XCode frameworks whose APIs still make sense.

Most of the time, but not always, when running tests for some projects depending on KmmResult (and thus, transitively depending on arrow-core) from IDEA (not the CLI), we encounter java.lang.NoClassDefFoundError: arrow/core/NonFatalOrThrowKt.

As a consequence, testcases fail all over the place and debugging becomes impossible. A nasty workaround is to define the nonFatalOrThrow function in our test sources to shadow the call to arrow, but we don't want that for obvious reasons.

This behaviour is independent of Kotlin version. We are using arrow-core 1.2.4.
