hey! I'm trying to use Kotlin's JSR223 Scripting API for embedded DSLs in my Application. I have created the required "javax.script.ScriptEngineFactory" file in 
src/main/resources/META-INF/services
, and also included the
Copy code
implementation org.jetbrains.kotlin:kotlin-script-util:$kotlinVersion"
implementation org.jetbrains.kotlin:kotlin-script-runtime:$kotlinVersion"
implementation org.jetbrains.kotlin:kotlin-compiler-embeddable:$kotlinVersion"
dependencies, and am now trying to call a simple script using
Copy code
val scriptEngine = ScriptEngineManager().getEngineByExtension("kts")!!
println(scriptEngine.eval("1+5") as Int)
but It does not execute, as i'm getting a 
ClassNotFoundException: org.jetbrains.kotlin.scripting.compiler.plugin.repl.GenericReplCompiler
any ideas what causes this / how to fix it? thanks!
Some more stacktrace

Which kotlin version are you using? If your using 1.3.50 and up you need to add a few dependencies for the runtime environment.
Copy code
runtime "org.jetbrains.kotlin:kotlin-scripting-compiler-embeddable:$kotlinVersion"
  compile "org.jetbrains.kotlin:kotlin-compiler-embeddable:$kotlinVersion"
But that may look from project to project different. There are maybe better solutions, but that is what worked for me.

thanks! i'm using 1.3.61, and adding these dependencies did change something, and it now actually executes! Sadly, i'm now getting a huge warning:

any ideas?
c
your dependencies are still wrong, they conflict with each other. try with:
Copy code
implementation("org.jetbrains.kotlin:script-runtime:$kotlinVersion")
runtimeOnly("org.jetbrains.kotlin:scripting-jsr223-embeddable:$kotlinVersion")
You can look at a working example here: https://github.com/AlexCzar/kotlin-script-demo

I am experiencing the same problem with a dependency clash. Is there a way to resolve it ? Or to detect where the dependency clash is? The build scan seemed fine to me, but I might have missed something. I also tried it with the build settings from the example project that was linked here by @Czar and the one from the test directory in Kotlin for 
KotlinJsr223JvmLocalScriptEngine
, but it throws the same error. Any help or suggestion is welcomed.
