Question about SyntheticResolveExtension and K2. We are currently trying to make our plugin K2 compatible but are running into a few problems. We cannot move to CompilerPluginRegistrar since we still depend on being able to control the ordering of plugins, but when we enable supportsK2 = true in ComponentRegistrar it doesn’t seem work. At least the extension is never run.

So right now I am assuming it is either a bug or SyntheticResolveExtension is not supported, but if it is the later what should we replace it with?

SyntheticResolveExtension is K1 specific
K2 alternative is FirDeclarationGenerationExtension

So just to be sure. If we continue to use ComponentRegistrar we need to detect what version of the compiler is running and either register FirDeclarationGenerationExtension or SyntheticResolveExtension or does FirDeclarationGenerationExtension also work with K1?

[dmitriy.novozhilov]

You can register both
Some just won't be used by the compiler

Cool. Thank you very much 🙏
