you need to add above android{} on your gradle

ext {
supportVersion='27.1.1'
}

The error tells that there is no value for the variable $supportVersion. If you know exactly what version you would like to use then define supportVersion like you have defined buildToolsVersion. I am not sure but its the same for your case. 

buildToolsVersion '27.0.3'
supportVersion '27.0.3'

Or replace supportVersion with buildToolsVersion in your existing file.
