hi all, I've recentlly updated to arrow 0.13.1 and facing some issue with the shouldBeRight { ... } function:

the error I get:

'java.lang.Object arrow.core.Either$Right.getB()'
java.lang.NoSuchMethodError: 'java.lang.Object arrow.core.Either$Right.getB()'

I have version 4.4.3 for kotest libraries, and updated the intellij kotest plugin (version: 1.1.31-IC-2021.1)
the shouldBeRight() function works as expected, only the shouldBeRight { value -> ...} fails.

Any help is apreciated, thank you!

The arrow assertions from the main kotest repo are based on 0.11.x

[sam]

try using the stand alone assertions package

https://github.com/kotest/kotest-assertions-arrow

[sam]

same stuff, but those are based on 0.13.x

[vio]

did use that
this is how the import looks like: import io.kotest.assertions.arrow.either.shouldBeRight

[sam]

definitely seems like a version mismatch at runtime

[sam]

If you do a gradle build scan you will be able to see if arrow 0.11 or 0.12 is sneaking in somewhere

[vio]

this gradle scan is awesome thanks 🙏

[sam]

yeah its good 🙂

[vio]

hopefully I'm looking in the right place (dependencies -> runtimeClasspath and testCompileClasspath) dependencies look ok

[sam]

There's gotta be something lurking I would say

[vio]

yep

@albertosh @vio the name of the values in arrow internal changed from .b to .value

@sam we might need to use fold instead of pattern matching to future proof kotest and avoid breaking changes and make it compatible with arrow 0.10 - > 0.13.x

the arrow module has been updated to 0.13.x so should work for .value, but yes in general I agree, fold will be more future proof
