Support the K2 Compiler about anvil HOT 12 OPEN

As far as I can see, there is no way of disabling it for Kotlin 2.0?

You can force language version 1.9 while still using Kotlin 2.0.0.

You can get fairly far with the 2.5.0 betas. I wrote some instructions here: https://www.zacsweers.dev/preparing-for-k2/#anvil. The TL;DR is that yes, projects with component merging will require language version 1.9, but any projects using just factory gen can use KSP instead.

We're working on it, we didn't expect the IR APIs we use to break in 2.0 as they weren't annotated as obsolete in the compiler.

With all due respect, that just means you're blocked on your internal policy, not anvil.

It will be released when it's ready. Out of respect for the many subscribers to this issue and general OSS etiquette, please accept this answer for now. We'll update this thread when there's something to update.

No ETA currently, we more or less have to get #751 and #704 done first

@ZacSweers I did, but it relies on a beta version of the anvil plugin. That's something we generally don't allow in our builds is any beta plugings or runtime dependencies. So i was curious when a release version of anvil will at least support the workaround.

Can the k2 warning be disabled (or shown only once)? It shows up literally thousands of times in build logs when K2 is enabled.

With 1.9.20 out and 2.0 next, is there an ETA for K2 support, as would love to start testing and sending feedback to the KT team.

K2 seems to be out and stable now. As far as I can see, there is no way of disabling it for Kotlin 2.0? So all Anvil projects are stuck at 1.9 for now.

This is definitely very unfortunate. One of the big boosts to using kotlin 2.0.0 is that the compose compiler is versioned and delivered along with the kotlin compiler. This is going to prevent people from using that new compose compiler alongside of anvil.

Is there any kind of a timeline as to when this support might be available?

@mattinger did you read the post I linked above?

That is a fair assessment @ZacSweers , which is why i'm asking if there's an ETA on a release version where the workaround will be applicable. It's a beta09 if i remember correctly, so i would think it won't be far off. The again, it is a build tool, and not something we're distributing, so i might be able to get an exception.

from anvil.

I was not implying that anyone should rush anything. I was just asking if you did have an ETA so i can make an informed decision on trying to get usage of the beta version approved. If the answer is that there's no current ETA, that's fine.
