Android studio, strange error while building kotlin: wrong code generated

Question

I'm trying for a few days to build my android project (contains mostly kotlin)... I tried to change versions for everything, and I keep getting the same error while building!

The message I'm getting looks like this:

Kotlin Compiler:

org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: wrong code generated

Java Compiler:

org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: Couldn't transform method node:

java.lang.IllegalArgumentException

I didn't do any dramatic change that could cause it to happen... I tried to rebuild, clean, delete everything, change versions for everything, but I still can't get rid of that.

How can I solve this?

Thanks!

This Kotlin issue has very similar error stack trace; https://youtrack.jetbrains.com/issue/KT-23941 (and also code to reproduce the issue if it happens to look familiar). — harism, Jul 22 '18 at 22:31

I too have faced the same error

It's mainly due to when you initialize any layout field without assigning the value to it.

  fab_add_vehicle.setOnClickListener { view ->


        if (add_note_lnr.visibility == View.VISIBLE && add_vehicle_lnr.visibility == View.VISIBLE) {

            add_note_lnr.visibility = View.GONE
            add_vehicle_lnr.visibility = View.GONE


        } else {
            add_note_lnr.visibility = View.VISIBLE
            add_vehicle_lnr.visibility = View.VISIBLE

            add_note_lnr //This the line of code which is causing the error: wrong code generated. Search in your code this kind of calling the UI fields and not using it

        }
    }

So there may be chances that you are not using the field which you just called. Please review your code from any class and remove that field

Above is my code which was causing the issue which I removed and issue disappear.

Error : e: org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: wrong code generated

Ref images Line of code causing the issue

You are a life saver, this should get more upvotes. Thanks bro. — Sharp Edge, Nov 29 '19 at 12:34
Your example helped me, in my case, it was binding.ediText.text!!.clear. I switched it to binding.ediText.text!!.clear(), and it worked! — Mrityunjay Kumar, Jul 16 '20 at 18:54
i spent 2 hours and didn't notice flying view name in the code. +1 — Aks4125, Aug 14 '20 at 06:51
