A modern programming language that makes developers happier.

kotlinlang

I've added a stability configuration file (<https://developer.android.com/jetpack/compose/performance/stability/fix#configuration-file>) and got it to work fine, _except_ when combined with configuration cache.
ksp task fails with "arraycopy: element type mismatch: can not cast one of the elements of java.lang.Object[] to the type of the destination array, java.lang.String"
Has anyone experienced anything similair?
More details in:thread:

Configuration file is added with:

`tasks.withType(KotlinCompile).configureEach {`
    `kotlinOptions.freeCompilerArgs += [`
            `"-P",`
            `"plugin:androidx.compose.compiler.plugins.kotlin:stabilityConfigurationPath=$rootDir/compose/compiler_config.conf"`
    `]`
`}`

this is the exception I get:

`org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':applibs:common:kspDebugKotlin'.`
        `at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.lambda$executeIfValid$1(ExecuteActionsTaskExecuter.java:148)`

ah, that's probably Groovy's GString getting in the way

see <https://github.com/google/ksp/issues/1367>

and consider using build.gradle.kts which doesn't have this problem (and many others)

Thank you!!! That fixed the issue.

Migrating to kotlin DSL is on the list of future work yes :)

(and what fixed the issue was doing:

```tasks.withType(KotlinCompile).configureEach {
    kotlinOptions.freeCompilerArgs += [
            "-opt-in=kotlinx.coroutines.ExperimentalCoroutinesApi",
            "-P",
            "plugin:androidx.compose.compiler.plugins.kotlin:stabilityConfigurationPath=$rootDir/compose/compiler_config.conf".toString()
    ]
}```
