Neo4J Java程序示例失败,错误为

我正在尝试运行下面提到的基本neo4j java程序( https://neo4j.com/developer/java/ ,使用maven。

虽然我可以成功编译,但是当我运行它时,我得到一个运行时异常,表明程序找不到类,如下所示。

java com.ravi.nFourJ.App

这是我的pom.xml文件。

我做了mvn编译,在project dir下创建了一个名为'target'的文件夹。

└── target
    ├── classes
    │   └── com
    │       └── ravi
    │           └── nFourJ
    │               ├── App$1.class
    │               └── App.class
    └── maven-status
        └── maven-compiler-plugin
            └── compile
                └── default-compile
                    ├── createdFiles.lst
                    └── inputFiles.lst

在我导航到“target/classes”目录并运行程序之后

java com.ravi.nFourJ.App

它给出了上述错误。

1. 我在这里做错什么了吗?
2. 在哪个依赖项中找到包/类“org/neo4j/driver/v1/transactionwork”?
