Neo4J Scala incorrect version? - maven-2

Question

I'm trying to use Neo4J embedded in my Java application. I'm using spring-data-neo4j, and allowing that to resolve dependencies. I'm getting an error when I start the application:
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

I'm using Spring-data-neo4j 2.2.0.RELEASE and Neo4J server 1.8.1. The relevant parts of my pom.xml look like this:
<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>
The error in the logs suggests that the version of Scala is wrong, but as far as I can see, I'm using the version that comes as part of the Neo4J dependencies.
Can anyone help me with getting the dependencies sorted out so the app has the right library versions?
