Based on the response #4165 (comment), this will not be implemented.

[xiaozhikang0916]

So, according to #4327 (comment) and #4165 (comment), if I need to use string resources in multiple modules with compose, I have to extract those resources in one public module and export all the resources by handwriting codes?

This isn't really an acceptable solution.

• Multimodule projects are not supported yet. The JetBrains team is working on adding this functionality in future releases. For now, store all resources in the main application module.

• The publication of Compose Multiplatform libraries with resources is not supported yet. The JetBrains team is working on adding this functionality in future releases.

Currently, there are some limitations in underlying things that block us from doing this. We're working with Kotlin and other teams to make this happen.

Please consider making the default visibility public of the generated Res class for the current limitations to avoid the boilerplate exposing fields or hacking scripts.

#4327 (comment)

[xinzhengzhang]

Is it possible to add at least a turn off switch to control the resource itself if it is not expected to use the resource? Or is it more recommended not to use the composeResources directory in this case?

[terrakok]

Could you explain your problem? I don't get it

Could you explain your problem? I don't get it

Main reasons:
I am using bazel to organize kmm projects, and will generate ide projects (gradle) for R & D similar to rules_xcodeproj for iOS. For some generate artifacts (ksp & kapt) I currently have my own generation pipeline and do not use gradle plugin. This is why I want to be able to control the production products (Res) myself.

Other reasons:
Currently there are many limitation on using Res, such as requiring the use of one module to integrate Res, and handwriting template code to expose internal resources is not very friendly, and I will even consider analyzing the Res pipeline to make these internal resources public. This is also I hope there is a switch to turn off this part, and I manage the pipeline generation of integrated Res myself

Thank a lot for the support!
In addition, I would like to confirm about Resources.Options

So far I see only enum class ResourceClassGeneration {Auto, Always} I would like to ask if there are plans to separate the Resource compile tool like aapt in android and open {Never} to add more freedom for some customization scenarios?
