Unable to build in android gradle plugin 3.3.2

This is the error I came across while building the project:

*The specified Android SDK Build Tools version (27.0.3) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.3.2.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '27.0.3'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.
*

I even Removed Build Tools version and synced the project again, but it failed again.

Affected Modules: app, authdemo
