This error is likely due to the fact that the simple jar task doesn’t take all its runtime dependencies.

From gradle documentation, In your build.gradle.kts you can either create a "fatJar" task or add that to your jar task:

tasks.withType {
    // Otherwise you'll get a "No main manifest attribute" error
    manifest {
        attributes["Main-Class"] = "com.example.MainKt"
    }

    // To add all of the dependencies
    from(sourceSets.main.get().output)

    dependsOn(configurations.runtimeClasspath)
    from({
        configurations.runtimeClasspath.get().filter { it.name.endsWith("jar") }.map { zipTree(it) }
    })
}
