Apache nifi 在NiFi中使用缓存处理器时获取InvalidClassException

我试图使用NiFi中的PutIgniteCache处理器将一些流文件放入Ignite缓存，但从我看到的SerialVersionUID中存在一些不匹配。你知道我怎么解决这个问题吗

我使用的是NiFi版本1.9.0、Ignite版本1.6.0和Java 8

以下是我收到的错误：

您似乎已经将JCache1.0与JCache1.1混合在一起（在同一个节点上的不同节点上）。确保类路径中只有一个版本的JCache（

cacheAPI-*.jar

）

FWIW，这看起来像是一个可操作的bug（我在NiFi PMC上）。我建议你把这个放到我们的用户列表中，这样我们就可以开始讨论了。
