Google Docs Java API 的构建问题
我正在尝试使用一些谷歌文档功能，我决定学习他们提供的基本教程 这里
我按照他们的指示进行操作，但在尝试运行时出现以下错误：
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/Maps

我仔细检查了我的构建路径中是否具有所需的所有依赖项，我知道它们在我的项目中得到了认可，因为当我从引用的 API 实例化对象时，IDE 不会抱怨。
任何帮助将不胜感激。
I'm trying to get some google docs functionality going and I've decided to do the basic tutorial they provide here
I followed their instructions to the T but got the following error when I tried to run:
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/Maps

I double checked that I had all of the dependencies that were required in my build path, and I know they are recognized in my project because the IDE isn't complaining when I instantiate objects from the referenced API's.
Any help would be appreciated.

我缺少以下 Jar，这显然是需要的，但在教程中没有提到。
I was missing the following Jar which is apparently needed but not mentioned in the tutorial.
