Failed to install the following SDK components:
build-tools;30.0.3 Android SDK Build-Tools 30.0.3
Install the missing components using the SDK manager in Android Studio.

Screw you. I am not installing Android Studio. It is the worst

I was getting this error when installing an android build tool:

.\sdkmanager.bat "build-tools;30.0.3" --verbose

Unable to create file or properties. The problem was the administrator rights. Run the same using CMD as an Administrator
