Include the following as a dependency:

implementation "android.arch.lifecycle:extensions:1.1.1"

This dependency is for both ViewModel and LiveData and thus would not require you to give separate dependencies for the same either; i.e. the first two dependencies indicated by you can be replaced by the aforementioned lifecycle extensions dependency.
