[Question] Build Error: The option setting 'android.enableR8=false' is deprecated

[ArneBAR1]

Hey,

When I try to build for Android I receive the following error:

Starting a Gradle Daemon, 1 incompatible and 1 stopped Daemons could not be reused, use --status for details

Hello! This looks like an intermittent compilation issue that we cannot reproduce with a clean version of the project. Maybe the Android build settings are in a broken state, or the Android SDK isn't correctly installed with Unity? It might be worthwhile to restart with a clean version of the project. Cheers, Florian

Hi again, the following forum entry might be related or not:

https://forum.unity.com/threads/do-we-have-a-solution-for-warning-the-option-setting-android-enabler8-false-is-deprecated.1250713/

Maybe the mitigation steps apply to your case as well.

Cheers, Florian

Hey Florian, I fixed it by removing my other unity editor versions and removing .android and .gradle file under "C:\User\MYCurrentUser" and then reinstalling the needed unity version.
