我正在尝试运行教程google drive api测试

我几乎提到了所有罐子，并且已经下载了config.json文件。但是我收到以下错误

我已经尝试了stackoverflow.com/questions/50687434/error-running-spark-main-class-exception-in-thread-thread-0-java-lang-noclas中提到的多个答案，但这对我没有帮助。我还附加了我的buildpath依赖项。请让我知道问题是什么。

我用蚂蚁和月食。

解决方法

经过多次试验，对我有用的是：

1. 添加了guava-11.0.2.jar
2. 已删除google api客户端json 1 2 3 alpha.jar
3. 重新下载了credential.json
4. 开始一个新项目，仅在资源文件中包含所需的jar，如附件所示
