I have a Multi Module KMP + CMP Project with a separate Non-CMP module just for Data Models
Now whats happening is that when I generate Compose Compiler Report, all my composable which take those models as parameter as shown as "Not Stable"

The solution I know is to make that data models module a CMP Module, add compose-runtime and mark all data classes with @immutable, but I dont want to make my data layer modules a CMP Module

Is there any other way of achieving it?

You can enable just the compose compiler on that module for it to apply the right stability to those classes

Or read this https://fvilarino.medium.com/exploring-jetpack-compose-compilers-stability-config-f1ccb197d6c0 so that you can manually explain which classes are supposed to be considered stable with a text file.
Go read at “Enabling the stability argument” and on

I'm facing this error

e: Unsupported plugin option: androidx.compose.compiler.plugins.kotlin:stabilityConfigurationPath=/Users/vaibhav/Projects/Medial/MedialMultiplatform/shared/stability-config.txt

I'm on Compose Multiplatform 1.5.12

This is how my plugin args looks like

kotlinOptions {
            // Trigger this with:
            // ./gradlew assembleRelease -PenableMultiModuleComposeReports=true --rerun-tasks
            if (project.findProperty("enableMultiModuleComposeReports") == "true") {
                freeCompilerArgs += listOf("-P", "plugin:androidx.compose.compiler.plugins.kotlin:stabilityConfigurationPath=$rootDir/shared/stability-config.txt")
                freeCompilerArgs += listOf("-P", "plugin:androidx.compose.compiler.plugins.kotlin:reportsDestination=" + rootProject.buildDir.absolutePath + "/compose_metrics/")
                freeCompilerArgs += listOf("-P", "plugin:androidx.compose.compiler.plugins.kotlin:metricsDestination=" + rootProject.buildDir.absolutePath + "/compose_metrics/")
            }
        }

I’ve never used it myself tbh, just pointed you to an article I’ve seen about it 🤷
