Android R8 issue with version 2.8.6

[shubhambansal]

I started getting the following error after updating to version 2.8.6. Until 2.8.5 everything works fine.

https://issuetracker.google.com, using 'Shrinker (R8)' as component name. You can
disable R8 by updating gradle.properties with 'android.enableR8=false'.

I have the same issue when used Android Gradle plugin v3.4.0 and Gradle v5.1.1 to build Apk. My workaround is Android Gradle plugin upgrades to 3.5.3 and Gradle upgrades to v5.5 then succeed to build Apk. But in build log still seen

Can you please check if this issue still occurs with the latest Gson version? The way the module-info.class file is included in the Gson JAR was changed and should hopefully now cause fewer issues. Also make sure to use the latest build tools and plugins (e.g. Gradle).

I am going to close this because no answer has been provided. If you still experience this with the latest Gson version, feel free to comment here again with more details.
