[Gopal S Akshintala]

Has anyone faced this error with latest Kotest: 4.6.0 with Gradle 7.0, gradle-jvm:16, Kotlin: 1.6, Java: 16

Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class io.kotest.core.test.TestContext, unresolved supertypes: kotlinx.coroutines.CoroutineScope
Adding -Xextended-compiler-checks argument might provide additional information.

do you have coroutines in your test dependencies? from the error it seems that adding it could fix it

[Gopal S Akshintala]

No I dnt hv coroutines

[Gopal S Akshintala]

let me share my gradle file

[Gopal S Akshintala]

https://github.com/overfullstack/ds-algo/blob/master/build.gradle.kts

[Gopal S Akshintala]

I tried with 4.6.0 as well as the 4.7-snapshot of kotest

[Gopal S Akshintala]

only kotest in my dependencies uses coroutines

[Gopal S Akshintala]

from the error, it looks like something to do with Kotest @christophsturm

[christophsturm]

i think if you add coroutines as a test dependency the error will go away

[Gopal S Akshintala]

No it didn’t work! I get a stackoverflow
` at org.jetbrains.kotlin.codegen.coroutines.CoroutineTransformerMethodVisitor.spillVariables$findSuspensionPointPredecessors$dfs(CoroutineTransformerMethodVisitor.kt:722)

[Gopal S Akshintala]

Looks like a known issue: CompilationException: Back-end (JVM) Internal error: wrong bytecode generated (with coroutines) : KT-39285 (jetbrains.com)

[Gopal S Akshintala]

But shouldn’t Kotest take care of coroutine dependency?

[sam]

Coroutines should be included - sounds like a version clash as 4.6 is using 1.5 of coroutines

[sam]

What version of kotlin are you using

[Gopal S Akshintala]

I use Kotlin 1.5 as well

[Gopal S Akshintala]

You may find my Gradle file here, I control version from gradle.properties : https://github.com/overfullstack/ds-algo/blob/master/build.gradle.kts

[sam]

I will clone and test. What command are you using in gradle?

[Gopal S Akshintala]

gradle clean build

[Gopal S Akshintala]

Gradle version I have is 7.0, with jvm 16.0.1

[Gopal S Akshintala]

Thanks!

Trying 1.8

[sam]

Oh this is a java project

[sam]

I will need to upgrade my version of java

[Gopal S Akshintala]

It's a mixed project with java and Kotlin

[Gopal S Akshintala]

Now i get this error in my other project as well which uses java 11

[Gopal S Akshintala]

I observed this error started after I used kotest-gradle plugin
