Cannot resolve YouTube class/symbol, YouTube Data API Java sample issue

问题

I'm trying to execute the Search by keyword sample code from YouTube Data API Java Samples collection.

In order to do that I:

1. Created a new project in IntelliJ IDEA.
2. Downloaded latest google-api-java-client-featured.zip.
3. Added the libraries from the google-api-java-client-featured to the project via Project Structure → Libraries → New Project Library.
4. Created a class Search.java and copy pasted the sample.

IDEA can't resolve YouTube class:

/**
 * Define a global instance of a Youtube object, which will be used
 * to make YouTube Data API requests.
 */
private static YouTube youtube;

My question:
Where can I find this YouTube class or what have I to do in order to be able to execute the official YouTube Data API Java sample?

It appears that there is more to download. You got everything except the actual YouTube Data API. As of this writing it can be found at https://developers.google.com/api-client-library/java/apis/youtube/v3. At that site there is the option to download a .zip file, or obtain through Maven or Gradle.

I found it by searching (googling) for the class com.google.api.services.youtube.YouTube, which I found listed as an import in the Sample that you linked above.
