java - jclouds 文件系统示例

Question

我正在尝试测试这个示例 http://jclouds.apache.org/guides/filesystem/但我收到此错误:

BlobStoreContext context = ContextBuilder.newBuilder("filesystem")
                 .overrides(properties)
                 .buildView(BlobStoreContext.class);

错误:

13:39:23 ERROR main step.AbstractStep - Encountered an error executing the step
java.lang.NoClassDefFoundError: com/google/gson/TypeAdapter
    at org.jclouds.rest.config.RestModule.configure(RestModule.java:62)

谢谢!

尝试将 Guava 从 14.0 升级到 15.0，以匹配 jclouds 对 Guava 的依赖。不要使用高于 15.0 的版本，因为 jclouds 1.7.x 解决了 Java 7u51 和 Guava < 16.0.1 之间的不兼容性问题，并且解决方法不支持更新的 Guava:
