Cannot resolve files when importing them Google API's

Question

I'm developing a Glassware for Google Glass. I'm trying to import these files:

import com.google.api.client.json.jackson.JacksonFactory;
import com.google.api.services.oauth2.Oauth2;
import com.google.api.services.oauth2.model.Userinfo;

but I'm getting errors on them. They are below:

The import com.google.api.client.json.jackson cannot be resolved
The import com.google.api.services.oauth2 cannot be resolved
The import com.google.api.services.oauth2 cannot be resolved

I'm not sure why I'm getting these errors. I'm building off of the quickstart java project. My Maven Dependencies are below:

Why am I getting these errors? Am I not importing a .jar? I can't find any .jar's that aren't included that should be, but there could be one. Thank you for your help.

Answer 1

Add the client libraries to the project.

See download and setup instructions for google-api-java-client.

Answer 2

try adding:

<dependency>
   <groupId>com.google.apis</groupId>
   <artifactId>google-api-services-oauth2</artifactId>
   <version>{version}</version>
</dependency>
