[Piflyer]

I was trying to run ./gradlew assembleDebug when this keep appearing`

Configure project :grpc The com.google.protobuf plugin was already applied to the project: :grpc and will not be applied again after plugin: android-library

FAILURE: Build failed with an exception.

• What went wrong: The Android Gradle plugin supports only Protobuf Gradle plugin version 0.8.6 and higher. The following dependencies do not satisfy the required version: root project 'sample-googleassistant-master' -> com.google.protobuf:protobuf-gradle-plugin:0.8.3

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

• Get more help at https://help.gradle.org

Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0. Use '--warning-mode all' to show the individual deprecation warnings. See https://docs.gradle.org/5.1.1/userguide/command_line_interface.html#sec:command_line_warnings

BUILD FAILED in 2s ` I tried Android studio 2.3, and the warning still persistently show. Is there a way to get rid of it. Thanks.

You're using Gradle v6? Isn't the latest version v5.x?

What version of the Android Studio Gradle plugin are you using?

I was able to solve this problem by downgrading the Gradle version in Project Structure. When I check back, it still keeps bugging me to update to Gradle 5.1.1, which is weird.
