Question

使用java客户端创建Cassandra Cluster对象时，我看到了以下异常。

 val cluster = Cluster.builder().
    withProtocolVersion(ProtocolVersion.V3).
    addContactPoint("127.0.0.1").
    build()

例外情况表示未找到com.google.common.util.concurrent.MoreExecutors.listeningDecorator方法。但是库（guava）被添加到classPath。

[error] Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.listeningDecorator(Ljava/util/concurrent/ExecutorService;)Lcom/google/common/util/concurrent/ListeningExecutorService;

show fullClasspath - 包含guava

将番石榴更新为最新版本。您还可以检查是否与任何其他JAR冲突。

java.lang.NoSuchMethodError：com.google.common.util.concurrent.MoreExecutors.listeningDecorator
