Kotlin compiler popup plugin not working

Question

I am using Realm and it needs an open keyword for model classes.

Following https://blog.jetbrains.com/kotlin/2016/12/kotlin-1-0-6-is-here/ , I tried using a pop-up compiler plugin to remove the open keyword from the classes of the Realm model.

First, I added a compiler popup plugin and set the annotation package name

 buildscript { dependencies { classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlin_version" } } apply plugin: "kotlin-allopen" allOpen { annotation("com.mycompany.myapp.annotation") } 

Secondly, I generated an annotation

 package com.mycompany.myapp.annotation annotation class AllOpenAnnotation 

Finally, I added an annotation to the Realm model class

 @AllOpenAnnotation class Model { var id: Int = -1, var title: String = "", var desc: String? = null }: RealmObject() 

But an error occurs error: cannot inherit from final Model .

Is there something I did wrong?

You need to add the annotation name to the path in your configuration file:

 allOpen { annotation("com.mycompany.myapp.annotation.AllOpenAnnotation") }
