hi, I'm having problem with running Kotlin .jar from Java, I'm writing plugin that works correctly when written in Java, but crashes when compiled with Kotlin, error is:
java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics
. I see that kotlin folder was correctly compiled into .jar

Check your dependencies, I've often seen this error when two different versions of stdlib are present in the project.
./gradlew :your:module:dependencyInsight --dependency kotlin-stdlib
replace
:your:module:
with your own values of course.

strange, i don't see any other versions here, my idea is problably wrong then.
oh, you're using gradle 4.10.2, it's not compatible with kotlin 1.3.0, if you're writing a plugin you should use 1.2.61 for 4.10.2

Adrian Wawrzak

11/16/2018, 1:36 PM
ok, let me check it
thank you, that led me to actual solution, .jar was properly built, but there was property that I need to set
JsonTransformation.Assertion.ui.allowed.packages=kotlin
now it works

Any link that an issue that kotlin 1.3 is incompatible with the latest Gradle version @Czar

From what I understand when you're writing a gradle plugin you have to use the version of kotlin bundled in gradle. That may or may not be the case, though. I should've added "I think so" 🙂
Since Adrian made it work, seems I wasn't right after all.
