I currently observe a strange behaviour when I create a distribution via wasmJsBrowserDistribution . Each time when I create a new distribution an additional .wasm file gets added to the distribution. See screen-shot. I am talking about the ones with 3.7 MB. After each real build (after a code change) an additional one is added. The previous ones get updated time stamps, which is also strange. This is a bug, right?

Same issue

[Michael Paus]

Even worse, when I manually clear the output folder all the previous .wasm files are re-created after the next build.

I’ve noticed the same thing 🤔

But if I do a gradle clean, it helps;
Went from 9 wasm-files to 2.

But having to do a gradle clean before each build slows down things quite a bit 🤨.

Ok, I will report it (after lunch 😉).

thank you for reporting!

Looks like the problem started with kotlin 2.1.0. No such issue with 2.0.21

I asked my colleague to take a look

I just want to add that I'm using Kotlin 2.1.0 with Compose Multiplatform 1.8.0-alpha01 (not compose-web) but I don't have this problem - only one wasm file is created for me.

Just a small notification that the above issue was just fixed. https://youtrack.jetbrains.com/issue/KT-73907/Wasm-Duplication-of-files-in-browser-distribution#focus=Comments-27-11344610.0-0
