Cannot call kotlin main class from command line

Question

I have a java project written in kotlin. main class is in kotlin. I have some JNI calls from different file of the projects. The problem is, I need to call the main class, which is written in kotlin from command line. Here is the command that I am using:

/Java/jre/bin/java -cp /app/cs/production/project/ com.test.project.Main u=$123 p=$123 host=$123 appimgv=$imgversion nocfg &

It generates this error:

#Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: kotlin/TypeCastException

What am I doing wrong over here? It works perfectly if I use java codes for main class with the extension .java to the main file. It just does not work with .kt

Your classpath doesn't specify the Kotlin dependencies, only the classes of your own project — Mark Rotteveel, Mar 08 '22 at 17:02
Here is an example: `java -Dkotlin.home="${KOTLIN_HOME}" -cp "${KOTLIN_HOME}/lib/kotlin-runner.jar" "org.jetbrains.kotlin.runner.Main" Main` — Darkman, Mar 08 '22 at 17:22
