I've more or less finished porting my <FloatingActionButtonSpeedDial> library to Compose and I'm now...

# compose

I've more or less finished porting my FloatingActionButtonSpeedDial library to Compose and I'm now in the process of publishing it to maven central but, when I generate the AAR, I can't understand why, all the composable classes throw an Unresolved reference.
The crazy thing is that the the enum on the same package is perfectly fine. And so is the AAR of the classic view library.

And of course the issue does not happen if I import the gradle module directly instead of using the AAR.

Do I need to do something special to generate an AAR with Composable?

build.gradle of the library module

I really don't get it, the classes seem to be there:

[tad]

They aren't there, actually. The *Kt.class files are just the top-level declarations from the .kt file, not the classes that are missing from that import list.

[Roberto Leinardi]

I said classes but it's not a class, it's just a composable annotated function, and it's there, or am I missing something?

[tad]

Ah, okay. That's strange, I'm not sure why they would be stripped from the AAR.

[Roberto Leinardi]

I really don't know what else to try, I went on github and checked a bunch of different compose libraries and I can't find anything special inside the build.gradle...
It's so frustrating: after all the effort to port the library now I'm blocked by this weird bug...

[tad]

One thing that gives me pause is setting targetSdkVersion for a library project; usually you specify a minSdkVersion and let the consuming application set the target, otherwise there are some arcane rules used by the manifest merger

[tad]

You appear to be excluding the consumer-proguard rules as well

[tad]

And *.kotlin_module which would probably explain why the top-level functions aren't being resolved

[tad]

Where did that config come from? I would clear out packagingOptions and only add what's necessary to get the project to build

[Leland Richardson [G]]

you might want to ensure that the module you are calling them from is using the Compose Compiler

[Albert Chang]

I can't tell from the build script but yes this looks like the symptom when you strip out META-INF/<module name>.kotlin_module from the aar. That file is needed to access top-level members.

[Roberto Leinardi]

@tad thank you for the suggestions. targetSdkVersion set for all the modules via build conventions

[Roberto Leinardi]

oh wow! The packagingOptions exclusion list was causing the problem! I don't remember from where I took that list but it never occurred that could have these side effects on AAR (I'm using it for months on a couple of apps without issue). But yeah, from now on I'll drop it and just manually add only what's needed.
Thanks a lot!
