未解决的参考设置Titan

我想使用Cassandra和Java来设置Titan。未解决的参考设置Titan

我导入库到我的项目使用：

compile group: 'com.thinkaurelius.titan', name: 'titan-cassandra', version: '1.0.0'

，我从复制的源例子：

https://github.com/thinkaurelius/titan/blob/master/titan-core/src/main/java/com/thinkaurelius/titan/example/GraphOfTheGodsFactory.java

但下面的东西不起作用：

import com.thinkaurelius.titan.core.TitanKey; 
import com.thinkaurelius.titan.core.attribute.Geoshape; 
import static com.thinkaurelius.titan.graphdb.configuration.GraphDatabaseConfiguration.INDEX_BACKEND_KEY; 
import static com.thinkaurelius.titan.graphdb.configuration.GraphDatabaseConfiguration.STORAGE_DIRECTORY_KEY;

不存在

012因为个

及以下抛出错误，他无法解析引用：

Configuration storage = config.subset(GraphDatabaseConfiguration.STORAGE_NAME_SPACE); 
    storage.setProperty(GraphDatabaseConfiguration.STORAGE_BACKEND_KEY, "local"); 
    storage.setProperty(GraphDatabaseConfiguration.STORAGE_DIRECTORY_KEY, directory); 

    Configuration index = storage.subset(GraphDatabaseConfiguration.INDEX_NAMESPACE).subset(INDEX_NAME); 
    index.setProperty(INDEX_BACKEND_KEY, "elasticsearch"); 


    index.setProperty(STORAGE_DIRECTORY_KEY, directory + File.separator + "es");
