Hello! Are there any repos or examples of how to use Kotlin script engine in Intellij plugin dev?
I’m trying to start with a simple code:

setIdeaIoUseFallback()
val engine = ScriptEngineManager().getEngineByExtension("kts")!!

I’ve added dependencies and /services/javax.script.ScriptEngineFactory file. But the engine is actually null. There is no factory for Kotlin in

ScriptEngineManager().engineFactories

If you depend on the Kotlin plugin it provides a different factory for the script engine manager

org.jetbrains.kotlin.jsr223.KotlinJsr223JvmScriptEngine4Idea

[raulraja]

The issue with this factory is that the first time you invoke it and tries to connect to the kotlin compiler daemon it calls Thread.stop and it blows up with a ThreadDeath exception.

@gammanik what does setIdeaIoUseFallback() do?

I guess I need to do something like this

val clazz: Class<*> = Class.forName("org.jetbrains.kotlin.script.jsr223.KotlinJsr223JvmLocalScriptEngine")
val factory: ScriptEngineFactory? = ScriptEngineManager(clazz.classLoader).getEngineByName("kotlin")?.factory

[gammanik]

ScriptEngineManager(clazz.classLoader)

Instead of empty construtor

I get it from gere

At least this way I can see the factory

[gammanik]

setIdeaIoUseFallback() does nothing

thanks!
