问题：
Unsupported method: AndroidProject.getPluginGeneration().
The version of Gradle you connect to does not support that method.
To resolve the problem you can change/upgrade the target version of Gradle you connect to.
Alternatively, you can ignore this exception and read other information from the model.

General Issue:-
It can occur because AS was checking availability of the Instant Run feature. The fixed is to disable Instant Run:
Windows & Linux:
File -> Settings -> Build, Execution, Deployment -> Instant Run.
Mac:
Android Studio -> Preferences -> Build, Execution, Deployment -> Instant Run.
