Java 如何在Eclipse中使用Google日历API jar文件创建事件？

我在后面遇到了困难。我正在EclipseIDE中编写一个简单的Java类，它能够在我的Google日历中插入一个新事件

我已经下载并将生成路径添加到我的项目中。此外，我还为谷歌日历API创建了凭据，并下载了client_secret.json文件

我正在使用：

import com.google.api.client.util.DateTime;
import com.google.api.services.calendar.model.Event;
import com.google.api.services.calendar.model.EventAttendee;
import com.google.api.services.calendar.model.EventDateTime;
import com.google.api.services.calendar.model.EventReminder;

public class CreateEventCalendar {
    // Refer to the Java quickstart on how to setup the environment:
    // https://developers.google.com/google-apps/calendar/quickstart/java
    // Change the scope to CalendarScopes.CALENDAR and delete any stored
    // credentials.

    Event event = new Event().setSummary("Google I/O 2015").setLocation("800 Howard St., San Francisco, CA 94103")
            .setDescription("A chance to hear more about Google's developer products.");

    DateTime startDateTime = new DateTime("2015-05-28T09:00:00-07:00");
    EventDateTime start = new EventDateTime().setDateTime(startDateTime)
            .setTimeZone("America/Los_Angeles");event.setStart(start);

    DateTime endDateTime = new DateTime("2015-05-28T17:00:00-07:00");
    EventDateTime end = new EventDateTime().setDateTime(endDateTime)
            .setTimeZone("America/Los_Angeles");event.setEnd(end);

    String[] recurrence = new String[] { "RRULE:FREQ=DAILY;COUNT=2" };event.setRecurrence(Arrays.asList(recurrence));

    EventAttendee[] attendees = new EventAttendee[] { new EventAttendee().setEmail("lpage@example.com"),
            new EventAttendee().setEmail("sbrin@example.com"), };event.setAttendees(Arrays.asList(attendees));

    EventReminder[] reminderOverrides = new EventReminder[] {
            new EventReminder().setMethod("email").setMinutes(24 * 60),
            new EventReminder().setMethod("popup").setMinutes(10), };
    Event.Reminders reminders = new Event.Reminders().setUseDefault(false)
            .setOverrides(Arrays.asList(reminderOverrides));event.setReminders(reminders);

String calendarId = "primary";event=service.events().insert(calendarId,event).execute();System.out.printf("Event created: %s\n",event.getHtmlLink());
}}

如何在谷歌日历中插入新活动？我如何授权申请？如何使用创建的凭据

任何帮助都将不胜感激

我在其他网站上找到了可能的解决方案，但没有一个有效：

在管理模式下运行eclipse

在DriveQuickstart.class.getResourceAsStream（“/client\u secret.json”）中更改

InputStream

to

InputStream in=newfileinputstream（“\\client\u secret.json”）

---

当我启动Quickstart类时，会创建一个“StoredCredentials”文件
