Spring Social ProviderSignInUtils.getConnection is returning "error: cannot find symbol" - spring

Question

I'm creating a controller to register an user that has logged in using oauth2 but whenever I try to get the connection using ProviderSignInUtils.getConnection(request) it says the function does not exist.
This is my controller:
import org.springframework.social.connect.web.ProviderSignInUtils;
#RequestMapping(value = "/register", method = RequestMethod.GET)
public String showRegistrationForm(WebRequest request, Model model) {
Connection<?> connection = ProviderSignInUtils.getConnection(request);
RegistrationForm registration = createRegistrationDTO(connection);
model.addAttribute("user", registration);
return "user/registrationForm";
}
Those are the maven dependencies:
<dependency>
<groupId>org.springframework.social</groupId>
<artifactId>spring-social-config</artifactId>
<version>1.1.2.RELEASE</version>
</dependency>

ProviderSignInUtils.getConnection was removed in Spring Social 1.1.2, however the documentation wasn't updated to reflect this. The example code at github shows this instead
#Inject
public SignupController(AccountRepository accountRepository,
ConnectionFactoryLocator connectionFactoryLocator,
UsersConnectionRepository connectionRepository) {
this.accountRepository = accountRepository;
this.providerSignInUtils = new ProviderSignInUtils(connectionFactoryLocator, connectionRepository);
}
#RequestMapping(value="/signup", method=RequestMethod.GET)
public SignupForm signupForm(WebRequest request) {
Connection<?> connection = providerSignInUtils.getConnectionFromSession(request);
if (connection != null) {
request.setAttribute("message", new Message(MessageType.INFO, "Your " + StringUtils.capitalize(connection.getKey().getProviderId()) + " account is not associated with a Spring Social Showcase account. If you're new, please sign up."), WebRequest.SCOPE_REQUEST);
return SignupForm.fromProviderUser(connection.fetchUserProfile());
} else {
return new SignupForm();
}
}
You need to create your own local providerSignInUtils so it has access to the connectionFactoryLocator and connectionRepository.
