gradle version causes AS to fail build

[MNDaveC]

build.gradle still using gradle 1.0.0 causes Android studio 2.2.2 to fail build... PLEASE UPDATE throughout all course projects.
classpath 'com.android.tools.build:gradle:1.0.0'

hey there even I'm facing a similar issue... how do I resolve this:

Error:Unsupported method: BaseConfig.getApplicationIdSuffix().
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.

@SachitNayak I resolved this by just updating the gradle version, it is unfortunate that the course author is not maintaining the project to keep it working. I'm currently using the following in my production projects:
com.android.tools.build:gradle:3.0.1
