Cannot compile the project

[nordfalk]

If you clone and open the project with Android Studio 3 you get this error message:

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.

I tried modifying
classpath 'com.android.tools.build:gradle:1.1.3'
to
classpath 'com.android.tools.build:gradle:3.0.0'
but I get another error (Error:The "android" command is no longer included in the SDK. Any references to it (e.g. by third-party plugins) should be removed.)
