I'm new to Gradle, but recently I wanted to use Kotlin-Jupyter notebook for a project.
I followed the instructions, I cloned the repo at https://github.com/Kotlin/kotlin-jupyter...
Throughout my struggles, I have gone through 5 or 6 errors, all of which have taken days to fix.
I am getting this new error when typing in the command gradlew install
, it is an internal exception:
> Task :kotlin-jupyter-publish:compileKotlin FAILED
The `kotlin-dsl` plugin applied to project ':kotlin-jupyter-publish' enables experimental Kotlin compiler features. For more information see https://docs.gradle.org/6.8.2/userguide/kotlin_dsl.html#sec:kotlin-dsl_plugin

Yes, it is quite long. I am unsure what the cause of the error is - to be quite frank, I'm a a beginner when it comes to Gradle. I was wondering why I am getting this error and how I could fix this.
Again, just recently I installed the JDK and set the environment variable for the JDK. I am not sure if the error has risen because of this, if so - here is my environment variable, maybe I have set it wrong:
C:\Program Files\Java\jdk-16
