Jdbc pentaho与Neo4j数据库的连接：错误

我下载了pentaho的社区版来创建仪表盘。 我的电脑上有一个Neo4j数据库，里面有我的数据。 当我尝试将报告连接到Neo4j数据库时，出现了一个无法解决的错误

我在报告design/lib/jdbc文件中添加了在市场上找到的Neo4j连接器tht

我打开pentaho，创建一个新报告，并添加一个新的JDBC连接，该连接类型为generic database，包含以下信息：

作为泛型数据库的连接类型 自定义连接URL为jdbc:neo4j://localhost:7474 自定义驱动程序类名为org.neo4j.jdbc.driver

Neo4j正在运行

当我点击test时，我有以下错误：

Erreur lors de la connexion à la Base de données [Neo4j connection] : org.pentaho.di.core.exception.KettleDatabaseException:

Error connecting to database: (using class org.neo4j.jdbc.Driver)
