GoogleCredential.Builder() cannot be resolved - oauth-2.0

Question

I am developing a Service Account application to obtain Token for accessing downstream services. However, I am facing an issue with compilation. Eclipse prompts an error "The type com.google.api.client.auth.oauth2.Credential$Builder cannot be resolved. It is indirectly referenced from required .class files". Code snippet below:
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson.JacksonFactory;
public class AppMain {
public static void main(String[] args) {
// TODO Auto-generated method stub
final HttpTransport TRANSPORT = new NetHttpTransport();
final JsonFactory JSON_FACTORY = new JacksonFactory();
GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(TRANSPORT)
.setJsonFactory(JSON_FACTORY)
.setServiceAccountId("SOMETHING#developer.gserviceaccount.com")
.setServiceAccountScopes(BigqueryScopes.BIGQUERY)
.setServiceAccountPrivateKeyFromP12File(new File("key.p12"))
.build();
}
}
Please help. Thanks in advance.

Answer 1

I resolved this error with overriding google-api-client dependency to this -
<dependency>
<groupId>com.google.api-client</groupId>
<artifactId>google-api-client</artifactId>
<version>1.22.0</version>
</dependency>

I resolved above issue and getting token by adding one more jar in library "google-oauth-client-1.22.0.jar". Below is code snippet
GoogleCredential googleCredentials = GoogleCredential.fromStream(serviceAccount);
GoogleCredential scoped = googleCredentials.createScoped(
Arrays.asList(
"https://www.googleapis.com/auth/firebase.messaging"
)
);
scoped.refreshToken();
String token = scoped.getAccessToken();
