Hi,
I have no kotlin skills, but I am trying to add it (in fact upgrade to 1.3) in https://github.com/the-benchmarker/web-frameworks/pull/2951
Could someone help me ?
I have some messages Class 'kotlin.Unit' is compiled by a pre-release version of Kotlin and cannot be loaded by this version of the compiler on gradle 6.5 and kotlin 1.3.72

I'd ditch the + in the versions, as it sounds like a version mismatch is happening between Kotlin parts.

[waghanza]

sorry, you mean ?

[waghanza]

who thing it's a version mismatch ?

[Nikky]

could also be that you need to run gradle clean to make it behave.. but my money would also be on version mismatch to something like eap versions

try running gradlew dependencies ?

[waghanza]

is there a way to avoid eap ?

Could you check it using gradle 5.4.*?

[waghanza]

gradle version is provided by docker image no ?

[e5l]

It depends on your configuration. Usually we're using wrapper and specify it in gradle-wrapper.properties . But it also can be system global, without wrapper

[waghanza]

I do not override this, I prefer using the default
