@Ilya Muradyan there is something weird going on with the maven package for the kernel that I managed to reduce to a simple PoC:

I have one class that simply tries to embed the kernel:

import org.jetbrains.kotlinx.jupyter.IkotlinKt;
import java.io.*;


public class BugDemo {

    public static void main(String[] args) {
        IkotlinKt.embedKernel(
                new File(args[1]),
                null,
                null);
    }
}

a default gradle file as generated by IntelliJ for a new project that specifies the maven package as a dependency

plugins {
    id 'java'
}

group 'org.example'
version '1.0-SNAPSHOT'

repositories {
    jcenter()
    mavenCentral()
}

dependencies {
    implementation 'org.jetbrains.kotlinx:kotlin-jupyter-kernel:0.8.3.281'
}

Building then fails with:

gradle classes

> Task :compileJava FAILED
error: org.jetbrains.kotlinx.jupyter.libraries.ResolutionInfoProvider: class file for org.jetbrains.kotlinx.jupyter.libraries.ResolutionInfoProvider not found
/home/fmagin/gits/jupyter-gradle-test/src/main/java/BugDemo.java:5: error: cannot access ResolutionInfoProvider
public class BugDemo {
       ^
  class file for org.jetbrains.kotlinx.jupyter.libraries.ResolutionInfoProvider not found

FAILURE: Build failed with an exception.

I have no idea if this is a bug or if I am doing something wrong.

Does adding implementation 'org.jetbrains.kotlinx:kotlin-jupyter-shared-compiler:0.8.3.281' to build.gradle fix the problem?

[Florian Magin]

yes it does!

[Ilya Muradyan]

Well, I'll add shared-compiler as compile dependency for kernel artifact (it was runtime before)

[Ilya Muradyan]

Thanks for reporting

[Florian Magin]

No problem. I was chasing this down for hours and was thinking this was some weird caching or dependency issue with my setup

[Florian Magin]

What confuses me is that I already managed to setup automated CI builds for a project that uses the kernel and that worked.

[Florian Magin]

but that involved copying libraries around to accommodate the weird build process of Ghidra Plugins, so this might have been why it worked

[Florian Magin]

anyway, thanks for the quick response and fix!
