是否可以在编译时验证是否为Kotlin中的Factory类调用了所需的函数？

@Retention(AnnotationRetention.SOURCE)
@Target(AnnotationTarget.FUNCTION)
annotation class RequiredFunction

class MyFactory {
    @RequiredFunction
    fun doSomething() {
        // 实现具体的逻辑
    }
}

@AutoService(Processor::class)
class FactoryValidatorProcessor : AbstractProcessor() {
    override fun getSupportedAnnotationTypes(): MutableSet<String> {
        return mutableSetOf(RequiredFunction::class.java.canonicalName)
    }

    override fun process(annotations: MutableSet<out TypeElement>?, roundEnv: RoundEnvironment?): Boolean {
        roundEnv?.getElementsAnnotatedWith(RequiredFunction::class.java)?.forEach { element ->
            // 检查函数是否被调用
            // 如果没有被调用，可以在编译时报错或警告
        }
        return true
    }
}

dependencies {
    // 其他依赖
    implementation 'com.google.auto.service:auto-service:1.0-rc7'
    annotationProcessor 'com.example:factory-validator-processor:1.0'
}
