Anyone having trouble with multi-platforms projects and 1.3.10?

I'm getting this:
(if it makes any difference, I'm using the Gradle Kotlin DSL)

> Task :common:compileKotlinCommon FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':common:compileKotlinCommon'.

I think the Kotlin DSL is known to be incompatible with the multiplatform plugin, but I haven't tried it myself so that might have changed recently.

Is it Gradle 5.0-rc? There's a known issue with Kotlin 1.3.10 and Gradle 5.0-rc, you need to either use Kotlin 1.3.0 or Gradle 4.10.2 until it's fixed: https://youtrack.jetbrains.com/issue/KT-28203

[Eugenio]

ohhhh

[Eugenio]

yeah I'm using 5.0-rc3!

[Eugenio]

thanks @h0tk3y

[serebit]

I’ve been having this issue as well, glad I found this!

[h0tk3y]

The fix should be available in Gradle 5.0-rc4, according to the comments on the issue mentioned above.

[Eugenio]

@h0tk3y there's a similar-ish issue that apparently happened between Gradle 4.10.1 and 4.10.2, where when trying to compile Kotlin I get (using <...> as a placeholder for "some classes"):

e: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class <...>, unresolved supertypes: <...>
    class <...>, unresolved supertypes: <...>

e: <...>.kt: (6, 12): Unresolved reference: <...>
e: <...>.kt: (27, 15): Unresolved reference: <...>

@Eugenio Please check your projects for implementation dependencies: those are not exposed for dependent modules' compilation. See this issue and comments: https://youtrack.jetbrains.com/issue/KT-28223
