Task ksoup entitescompileCommonMainKotlinMetadata FAILED

w: Language version 2.0 is experimental, there are no backwards compatibility guarantees for new language and library features
e: Compilation to metadata is not supported with language version 2.0 right now

I'm getting this error while building my project using K2
Kotlin gradle plugin: 1.8.20

[dmitriy.novozhilov]

1.8.20 does not support MPP compilation
It will be released in alpha stage in 1.9.0

@dmitriy.novozhilov I tried again after the 1.9.0-Beta release and it works fine, but the build time was the same. I tried it on my library Ksoup which contains only kotlin stdlib with no other dependencies, it's super lightweight so I though that it's not the best project to see the improvements.

[dmitriy.novozhilov]

Yeah, there is a more-or-less constant time of compiler initialization, which is the same for K1 and K2 compilers
And on small projects this time may be greater then compilation itself

[dmitriy.novozhilov]

Anyway, it's very good to know that you didn't faced any issues
Thank you for checking this!
