How to get rid of Incremental annotation processing requested warning during the build?

Question

I have just started using android development. I am facing this warning message

[kapt] Incremental annotation processing requested, but support is disabled because the following processors are not incremental: io.realm.processor.RealmProcessor (NON_INCREMENTAL).

I got a warning when I was programming with the book as a reference. I've looked into several solutions and tried, but couldn't find a solution. Please give me some advice.

Here's my build.gradle(Modules: app) files.

Incremental annotation processing support was added in 5.11.0. You are using 5.1.0. I don't remember the changelogs per version as well as I used to, so you might want to check the changelog to see what changed over time. https://github.com/realm/realm-java/blob/master/CHANGELOG.md — EpicPandaForce, May 05 '20 at 03:51
If you are NOT using the Realm Sync functionality (`Realm Object Server`), then you should be safe to update to 6.1.0. — EpicPandaForce, May 05 '20 at 03:54

You are using Realm-Java 5.1.0.

Incremental annotation processing was added to Realm in 5.11.0.

You should try to update to 6.1.0, the only breaking change was in regards to the Realm Object Server PermissionManager API, which you probably aren't using, but contains important bug fixes like the 6.0.1 fix regarding encrypted Realms.
