gradle谷歌驱动器依赖没有得到解决

Question

我正在尝试运行代码

import com.google.api.services.drive.Drive;
import com.google.api.services.drive.model.ParentList;
import com.google.api.services.drive.model.ParentReference;

import java.io.IOException;

// ...

public class MyClass {

  // ...

  /**
   * Print a file's parents.
   *
   * @param service Drive API service instance.
   * @param fileId ID of the file to print parents for.
   */
  private static void printParents(Drive service, String fileId) {
    try {
      ParentList parents = service.parents().list(fileId).execute();

      for (ParentReference parent : parents.getItems()) {
        System.out.println("File Id: " + parent.getId());
      }
    } catch (IOException e) {
      System.out.println("An error occurred: " + e);
    }
  }

  // ...

}

用于了解父母的详细信息。

添加的依赖项是

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.11'
    compile 'com.google.api-client:google-api-client:1.22.0'
    compile 'com.google.oauth-client:google-oauth-client-jetty:1.22.0'
    compile 'com.google.apis:google-api-services-drive:v3-rev59-1.22.0'
}

代码示例来自from this page

import com.google.api.services.drive.model.ParentList;
import com.google.api.services.drive.model.ParentReference;

以上导入实际上没有得到解决。请帮帮我。
