I'm trying to debug a failing test on Windows where I run a .class file from java . Maybe you'll spot what's wrong... details in the thread

[Piotr Krzemiński]

the execution looks like this:

java -cp C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes MainKt

and in C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes there are these files/dirs:`

- C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes
    - C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes\MainKt.class
    - C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes\META-INF
    - C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes\META-INF\main.kotlin_module
    - C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes\MutableMyClass.class
    - C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes\MyClass.class
    - C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes\MyClassCopyDslKt$copy$result$1.class
    - C:\Users\RUNNER~1\AppData\Local\Temp\Kotlin-Compilation13472995364104513328\classes\MyClassCopyDslKt.class

On MacOS/Linux, it works fine

on Windows, I'm getting java.lang.ClassNotFoundException: MainKt

tried playing with kind of slashes, but it doesn't help

reproducible in this PR: https://github.com/krzema12/snakeyaml-engine-kmp/pull/593

oh, I think the culprit is in separation of paths in classpath - I actually didn't include the other path in the executed command above. My code has : as separator, and on Windows it's illegal since we have e.g. C:\, so we need a semicolon. Trying it now

That was it

[Stefan Oltmann]

I work on a Windows app (because most people have that), but I develop it with a MacBook (because the experience is better). I stumble into these kind of issues all the time. 🫣

[Piotr Krzemiński]

As if Microsoft really, deliberately wanted Windows to be different in some areas... Like "we'll need extra support for Windows, so it's going to cost you" 😁

Well there are a lot of reasons for this going way back and it's really hard to objectively say if : or ; is a better separator.
