我正在尝试使用嵌入在我的 Java 应用程序中的 Neo4J。我正在使用 spring-data-neo4j，并允许它解决依赖关系。启动应用程序时出现错误：

我正在使用 Spring-data-neo4j 2.2.0.RELEASE 和 Neo4J 服务器 1.8.1。我的 pom.xml 的相关部分如下所示：
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-neo4j-aspects</artifactId>
<version>${spring-data-neo4j.version}</version>
</dependency>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-kernel</artifactId>
<version>1.8.1</version>
</dependency>
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>1.8.1</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.0.2.GA</version>
</dependency>
日志中的错误表明 Scala 的版本是错误的，但据我所知，我使用的是 Neo4J 依赖项中的版本。
任何人都可以帮助我整理依赖项，以便应用程序具有正确的库版本吗？
