How to use scripting in 1.3.30

Support
1

Until 1.3.20 I used scripting without problem in the following way:

  • Added resource file javax.script.ScriptEngineFactory into META-INF.services folder with content org.jetbrains.kotlin.script.jsr223.KotlinJsr223JvmLocalScriptEngineFactory

  • Added dependency to project:

    compile(kotlin(“stdlib-jdk8”))
    compile(kotlin(“script-util”))
    compile(kotlin(“script-runtime”))
    compile(kotlin(“compiler-embeddable”))

  • Initialized my code by

      private val engine: KotlinJsr223JvmLocalScriptEngine

  init {
      System.setProperty("idea.use.native.fs.for.win", "false")
      engine = ScriptEngineManager().getEngineByExtension("kts") as KotlinJsr223JvmLocalScriptEngine
  }

  • Used the eval on kts source like this

    val building = engine.eval(src) as Building

It works properly until kotlin version 1.3.20, but when I switched to 1.3.30 I got the following exception:

This suggests that there were some incompatible changes within the new version, but I was not able to find any information on this.

How should I evaluate scripts in 1.3.30?

Same problem in 1.3.31
