java.lang.NoClassDefFoundError：無法初始化類com.datastax.driver.core.Cluster

我有一個Maven項目爲項目A Ajava.lang.NoClassDefFoundError：無法初始化類com.datastax.driver.core.Cluster

的pom.xml：

<dependencies> 
     <dependency> 
      <groupId>com.app.cops</groupId> 
      <artifactId>cassandra-logging</artifactId> 
      <version>0.0.1-SNAPSHOT</version> 
     </dependency> 
</dependencies>

的pom.xml該項目卡桑德拉 - 日誌記錄：

的警察測井projecct具有下面的代碼：

CassandraCopsComponentLogger.instance = new CassandraCopsComponentLogger(); 

       String hosts = CassandraClientUtil.getHost(); 
       String localDC = CassandraClientUtil.getLocalDC(); 
       Cluster cluster; 
       if (StringUtils.isNotEmpty(localDC)) 
       { 
        cluster = Cluster.builder().addContactPoints(hosts.split(",")) 
          .withCredentials(CassandraCopsComponentLogger.USER_NAME, CassandraCopsComponentLogger.AUTH_CODE) 
          .withQueryOptions(new QueryOptions().setConsistencyLevel(ConsistencyLevel.LOCAL_ONE)) 
          .withLoadBalancingPolicy(new TokenAwarePolicy(DCAwareRoundRobinPolicy.builder().withLocalDc(localDC).build())).build(); 
       } 
       else 
       { 
        cluster = Cluster.builder().addContactPoints(hosts.split(",")) 
          .withCredentials(CassandraCopsComponentLogger.USER_NAME, CassandraCopsComponentLogger.AUTH_CODE) 
          .withQueryOptions(new QueryOptions().setConsistencyLevel(ConsistencyLevel.LOCAL_ONE)).build(); 
       } 

       Session session = cluster.connect(); 
       CassandraCopsComponentLogger.mappingManager = new MappingManager(session);

我不斷獲取以下行除外：

cluster = Cluster.builder().addContactPoints(hosts.split(","))

我在卡桑德拉測井項目單元測試，與此代碼工作正常。但是，當我打電話從項目中相同的代碼我得到的

java.lang.NoClassDefFoundError: Could not initialize class com.datastax.driver.core.Cluster

您的設置似乎罰款。項目A的構建是否成功？ – chaitan64arun

是的。項目A能夠成功構建 –

我能夠通過降級卡桑德拉依賴版本<version>2.1.9</version>解決這個問題。不知道這是如何幫助，但我能夠前進。

更新版本卡桑德拉驅動核心和卡桑德拉驅動器映射到3.3.0 - 這個工作對我來說：

 <dependency> 
      <groupId>com.datastax.cassandra</groupId> 
      <artifactId>cassandra-driver-core</artifactId> 
      <version>3.3.0</version> 
     </dependency> 
     <dependency> 
      <groupId>com.datastax.cassandra</groupId> 
      <artifactId>cassandra-driver-mapping</artifactId> 
      <version>3.3.0</version> 
     </dependency>
