我正在为 Google Glass 开发 Glassware。我正在尝试导入这些文件：

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

但我在他们身上遇到了错误。它们如下：

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

我不确定为什么会收到这些错误。我正在构建快速入门 java 项目。我的 Maven 依赖项如下：

为什么我会收到这些错误？我没有导入 .jar 吗？我找不到任何不应该包含的.jar，但可能有一个。谢谢您的帮助。

将客户端库添加到项目中。

请参阅google-api-java-client 的下载和设置说明。

尝试添加：

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