What does

java.lang.NoSuchMethodError: 'void Common_main$Strategy.<init>(java.lang.Boolean, Common_main$Matrix, int, kotlin.jvm.internal.DefaultConstructorMarker)'

want to tell me?
Obviously, it compiled fine, but now it does not run? o_O

The called constructor is

data class Strategy(
    val failFast: Boolean? = false,
    val matrix: Matrix? = Matrix()
) { ... }

And it is called like

Strategy()

The class decompiled to Java shows the constructor it is complaining about.

Hmmm

$ javap -p -c Common_main\$Strategy.class | grep DefaultConstructorMarker | grep Strategy
  public Common_main$Strategy(Common_main, java.lang.Boolean, Common_main$Matrix, int, kotlin.jvm.internal.DefaultConstructorMarker);
$ javap -p -c Branches_and_prs_main\$2.class | grep DefaultConstructorMarker | grep Strategy
      72: invokespecial #72                 // Method Common_main$Strategy."<init>":(Ljava/lang/Boolean;LCommon_main$Matrix;ILkotlin/jvm/internal/DefaultConstructorMarker;)V

Looks like a bug in the evaluator to me.
Could you, please, file an issue in YT?

[Vampire]

I wanted to. But I first have to reproduce. I was in a rush and juggled the code until it worked like I needed it and then was not able to instantly reproduce it.

[Vampire]

No, unfortunately I'm not able to reproduce right now and local history of the files is not available anymore. 😞
I could create an issue, but withot reproducer it will probably not help much.

[Vampire]

Oh, now I got it again. Will try to boil it down.

[Vampire]

Great, boiled it down to
foo.main.kts

@file:Import("bar.main.kts")

println(Foo())

and
bar.main.kts

class Foo(
    val bar: Nothing? = baz
) {
    companion object
}

val Foo.Companion.baz
    get() = null

=>

java.lang.NoSuchMethodError: 'void Bar_main$Foo.<init>(java.lang.Void, int, kotlin.jvm.internal.DefaultConstructorMarker)'
	at Foo_main.<init>(foo.main.kts:3)

[ilya.chernikov]

Thank you very much!

[Vampire]

Argh, all the effort just get it closed as a duplicate of an issue you reported 11 months ago. 🙈 😄

[ilya.chernikov]

I'm sorry. But it is always helps to have a second repro, so thank your anyway!

[Vampire]

Yeah, don't worry. 🙂

I just always hate getting things closed as duplicate.
Either means I was too lazy to search first or my search-fu failed on me.
And they probably do not count to the "you get a free all products pack" license issues. 😄

I think I have a similar issue… I tried to run an old script but suddenly it does not work

java.lang.NoSuchMethodError: 'void <http://org.slf4j.Logger.info|org.slf4j.Logger.info>(java.lang.String, java.lang.Throwable)'

[ribesg]

It's very weird, and also this script worked before. Something broke in an update to Kotlin. I wonder if and how I can roll it back

[ribesg]

In my case I'm referencing slf4j from like a 4-libs dependency chain so I don't think I can make a reproducer easily

[ribesg]

I don't know if it's the same issue. The one linked says it affects Kotlin 1.7.0. In my case, I have the error using Kotlin 1.8.20 but not 1.8.0.
I used sdkman to install different versions of kotlin (Homebrew does not have past versions)

[Vampire]

My issue was / is against 1.8.21

[ribesg]

Did you try rolling back to an earlier version of Kotlin (if you can)?

[Vampire]

No, I adapted my code to not trigger the bug 🙂

[ribesg]

Well I can't adapt my code to not use <http://log.info|log.info> 😄

[Vampire]

I didn't imply you could 😄
