Google 文档 Api 驱动没有方法导出

Google docs Api Drive no method export

我需要获取 pdf 格式的文档文件。我阅读了这篇文章 https://developers.google.com/drive/v3/web/manage-downloads 并尝试使用它,但我的驱动对象中没有方法导出。你能帮助我吗?

这是我的 Pom 文件:

<google-api-version>1.20.0</google-api-version>
<dependency>
            <groupId>com.google.api-client</groupId>
            <artifactId>google-api-client</artifactId>
            <version>${google-api-version}</version>
        </dependency>
        <dependency>
            <groupId>com.google.oauth-client</groupId>
            <artifactId>google-oauth-client</artifactId>
            <version>${google-api-version}</version>
        </dependency>
        <dependency>
            <groupId>com.google.apis</groupId>
            <artifactId>google-api-services-drive</artifactId>
            <version>v2-rev170-${google-api-version}</version>
        </dependency>
        <dependency>
            <groupId>com.google.oauth-client</groupId>
            <artifactId>google-oauth-client-jetty</artifactId>
            <version>1.21.0</version>
        </dependency>

将 POM 中的版本更改为此

<dependency>
        <groupId>com.google.apis</groupId>
        <artifactId>google-api-services-drive</artifactId>
        <version>v3-rev6-1.20.0</version>
</dependency>
