Android DataBinding KAPT Incremental Support

Question

I've looked at this answer and others on this site and using Google, but I have yet to find an answer that works for this problem. This is the remaining non-incremental annotation processor that is listed by the newest version of KAPT:

Incremental annotation processing requested, but support is disabled because the following processors are not incremental: android.databinding.annotationprocessor.ProcessDataBinding (NON_INCREMENTAL)

Please note that I have migrated to AndroidX and am using AGP 3.4.1 (cannot upgrade to AGP 3.5.x) and Gradle 5.5. Any help would be much appreciated.

cannot upgrade to AGP 3.5.x

That is going to be a problem. Quoting Google:

I am pleased to inform that data binding has become incremental, starting with AGP 3.5.0-alpha05. For safety we've put this feature behind a flag, currently off by default. To enable it, please set android.databinding.incremental=true in the Gradle properties file.

If you jump all the way to AGP 3.6.x (currently in alpha), incremental compilation is enabled by default.

However, on your version, AFAIK, incremental compilation support simply did not exist for the databinding stuff.

What does AGP stand for? – J Blaz Jun 23 '20 at 16:01

That is what I thought. I am on 4.0.0 and still have the warning. – J Blaz Jun 24 '20 at 17:22
@JBlaz: Does the warning go away if you add `android.databinding.incremental=true` to your `gradle.properties` file? – CommonsWare Jun 24 '20 at 17:28
No, it is still there. – J Blaz Jun 24 '20 at 20:38
OK, that may be worth a fresh SO question with a [mcve] showing what you have. – CommonsWare Jun 24 '20 at 20:42
