带有示例的官方 Google Cloud Java SDK答案

【问题标题】：Official Google Cloud Java SDK with examples带有示例的官方 Google Cloud Java SDK
【发布时间】：2021-03-23 06:26:25
【问题描述】：

另外，是否有一个示例 maven 项目说明使用 Java SDK 创建虚拟机/实例？以及一个示例，说明所需的所有依赖项和示例代码

寻找与 AWS Java SDK 非常相似的方法来创建 VM，如下面的链接 https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/javav2/example_code/ec2/src/main/java/com/example/ec2/CreateInstance.java

找到了这个，但不确定这是否是官方支持的 SDK。 https://github.com/googleapis/google-cloud-java 如果有创建 VM 的示例，请分享。
