Java – Google Calendar API not found – Calendar class missing

I’m trying to make an app that uses Google’s API for its calendar service. I’m referencing this guide and now stuck on one step. Specifically, >this step

It tells me to import these classes:

import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson.JacksonFactory;
import com.google.api.services.calendar.Calendar;
import com.google.api.services.calendar.model.*;

Now, I’ve downloaded the (I think complete) library: >this source.but it still gives me an error on the following two lines:

import com.google.api.services.calendar.Calendar;
import com.google.api.services.calendar.model.*;

Where can I get these two classes? Or should I follow another example? Any help would be appreciated.

To use the Google Calendar API, you need two specific libraries, which are:

• Calendar service java: https://developers.google.com/resources/api-libraries/download/calendar/v3/java
• Google API client java:https://code.google.com/p/google-api-java-client/downloads/detail?name=google-api-java-client-1.15.0-rc.zip&can=2&q=

And make sure to import all required jars.
That’s it.
