尝试使用EmbeddedCassandraServerHelper.startEmbeddedCassandra();方法，但一直收到此错误。除了configurationException类之外，我还可以针对该方法中抛出的异常访问每个类。不知道为什么它没有捡起来。我在下面发布了我所有的依赖项，希望这里的人能看到我错过的东西。谢谢
准确误差为java: cannot access org.apache.cassandra.exceptions.ConfigurationException class file for org.apache.cassandra.exceptions.ConfigurationException not found

这可能是另一个问题的症状。根据我的经验；类未找到"；在运行Cassandra时，使用较新版本的Java通常会出现异常。
Cassandra 3.11及更早版本仅适用于Java 8。Java 11支持直到Cassandra 4.0(Cassandra-16894(才添加。
使用较新版本的Java构建应用程序是可能的，但除非使用受支持的JVM，否则无法运行Cassandra。干杯
