java - Janus Graph - gremlin-server - Java 客户端 - 找不到 apache.commons.configuration 的类文件

Question

我尝试通过 Java 客户端访问 Cassandra 上的 janus 图，但无法通过 Client 类使用属性文件。

public static void main(){

    Cluster cluster = Cluster.open("remote.yaml");
//  Cluster cluster2 = Cluster.build();

    Client client = cluster.connect();
    graph = JanusGraphFactory.open("conf/janusgraph-cassandra-solr.properties");

错误:

Answer 1

这个问题也在 janusgraph-users 上被问到。谷歌集团。我在该帖子中的回答:

org.apache.commons.configuration.Configuration is not found in Apache commons-lang. It is in Apache commons-configuration.

There are a lot of dependencies for the JanusGraph/TinkerPop stack, so you're best approach would be to use a tool like Apache Maven or Gradle to manage the dependencies for your project, rather than adding the jars one by one. Please refer to the code examples included with the distribution.
