I just updated to 4.4.3 with kotlin 1.4.32 and am seeing some method not found exceptions in my build pipeline that I don’t see locally.

java.lang.NoSuchMethodError: 'java.lang.Object kotlinx.coroutines.DelayKt.delay-VtjQ1oo(double, kotlin.coroutines.Continuation)'
        at io.kotest.assertions.timing.EventuallyKt.eventually(eventually.kt:123)
        at io.kotest.assertions.timing.EventuallyKt.eventually$default(eventually.kt:77)
        at io.kotest.assertions.timing.EventuallyKt.eventually-rnQQ1Ag(eventually.kt:48)

Dropping back down to Kotest 4.4.1 seemed to work. Building on Java 11.

Yeah we've seen this before, duration is experimental in Kotlin and we shouldn't have used it. https://github.com/kotest/kotest/issues/2149

@Jim perhaps its worth getting this into 4.5 after all ?

[Jim]

Yeah I can get to that this week

[sam]

I don't mind doing the work, if we agree on an approach

[Peter]

https://blog.jetbrains.com/kotlin/2021/04/kotlin-1-5-0-rc-released/#duration-api-changes looks like it's remaining experimental for 1.5 😞

[sam]

Yeah that's really annoying

[Jim]

😞 just release it already

[Peter]

i've been trying 1.5 ... no go 😞

[Peter]

Caused by: java.lang.NoSuchMethodError: 'io.kotest.assertions.until.FixedInterval io.kotest.assertions.until.FixedIntervalKt.fixed-LRDsOJo(long)'

[Peter]

(works fine with 4.4.3 and 1.4.32)

[sam]

We're going to add a new eventually package that doesn't use durations at all. Hopefully within a few days

[Peter]

🙏

[Jim]

Yep gonna start on that tomorrow.. I need a break tonight

[sam]

Slacker ! ;)

[Peter]

thanks guys 😄

[Peter]

gents - did these changes make it in? eventually seems to be still using kotlin.time.Duration and it’s blowing up at runtime being a value class in kotlin 1.5 - am i doing something wrong?

[Peter]

Caused by: java.lang.NoSuchMethodError: 'java.lang.Object io.kotest.assertions.timing.EventuallyKt.eventually-D5N0EJY(long, kotlin.jvm.functions.Function1, kotlin.coroutines.Continuation)'

[Peter]

first parameter is a long

[Peter]

looks like code previously built against an inline class with 1.4 is not compatible with 1.5 where this particular class was changed to a value class? that seems alarming

[sam]

They have changed the durations yes

[sam]

So we need to rebuild teh eventually support - we're going to add a new package with a fresh implementation that doesn't use durations at all

[Jim]

“Slacker” is right 😞 gonna take a look at lunch today

[sam]

now that 4.5 is out, we can do this for a 4.5.1 release

[Peter]
