Component used: androidx.room:room-compiler

Version used: 2.7.0-alpha04

Compilation of the attached project fails with

e: file:///.../composeApp/build/generated/ksp/metadata/commonMain/kotlin/ExpenseDatabase_Impl.kt:25:8 Class 'ExpenseDatabase_Impl' is not abstract and does not implement abstract base class member 'clearAllTables'.

As figured out by others, creating an extra interface and making the database class inherit it fixes the problem:

interface DB {
    fun clearAllTables() {}
}

@Database(entities = [Expense::class, Person::class], version = 1)
abstract class ExpenseDatabase : RoomDatabase(), DB {
    abstract fun expenseDao(): ExpenseDao

    override fun clearAllTables() {
        super.clearAllTables()
    }
}

This fix is prepared in the attached sample project, uncomment to see it working.
