it looks like this is a known issue solved in `1 9 x` <https youtrack jetbrains com issue KT 56357>

Samuel Gammon · Answer

but the workaround is very mysterious to me ```publish pom packaging = klib org jetbrains kotlin gradle plugin VariantImplementationFactories getProvider project artifact tasks named wasmJar extension = klib ```

Samuel Gammon · Answer

Samuel Gammon · Answer

we have solved this it seems to be a bug where we are calling the JS IR compiler ``` kotlin + org jetbrains kotlin gradle plugin VariantImplementationFactories getProvider project js IR browser ``` inserting that line above the IR compiler config fixes it in case anybody else runs into this will file on youtrack slightly smiling face

Without knowing it or having looked into it the problem seems to be that the Kotlin plugin does something deferred that then happens to late at an unsupported time and with that call the action is done eagerly
