gt java lang ClassNotFoundException io kotest fp OptionKt This looks like a normal dependency error you seem to be using version of Kotest that requires Arrow but Arrow can t be found on the classpath

dave08 · Answer

Arrow I never used Arrow does the regular Kotest framework require it Or maybe it has something to do with the Robolectric extension I tried updating

dave08 · Answer

Thanks for the pointer I ll try to look into what s requiring Arrow

sam · Answer

OptionKt is part of kotest not arrow but i agree just looks like deps error
