Caused by: java.lang.IllegalStateException: Detected Guava issue #1635 which indicates that a version of Guava less than 16.01 is in use.  This introduces codec resolution issues and potentially other incompatibility issues in the driver.  Please upgrade to Guava 16.01 or later.

我尝试使用独立的java，它工作正常，但在我的项目中抛出错误。它在以下行抛出异常:

this.cluster = Cluster.builder().addContactPoint(node).withPort(port).build();

感谢您的指导。

您的类路径中必须有一个早于 16.0.1 的 Guava 版本。 java驱动仅支持Guava 16.0.1至19(即将发布的3.2.0将支持16.0.1至21)。

检查您的类路径中是否有旧版本的 Guava ，并将其替换为 16.0.1 和 19.0 之间的版本。您的应用程序的类路径中也可能有多个 Guava jar ，在这种情况下，您应该删除旧的。
