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.

我嘗試使用獨立的java並且它工作正常，但在我的項目中拋出錯誤。 它在以下行拋出異常：

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

感謝您的指導。

您的類路徑中必須存在一個早於16.0.1的Guava版本。 java驅動程序僅支持Guava 16.0.1到19（3.2.0將很快發布，將支持16.0.1到21）。

檢查類路徑以查找舊版本的guava，並將其替換為16.0.1和19.0之間的版本。 您的應用程序也可能在您的類路徑中有多個番石榴罐，在這種情況下您應該刪除舊的。
