我使用以下Mave依赖项：
<spring-data-neo4j.version>4.2.0.M1</spring-data-neo4j.version>
<neo4j-ogm.version>2.1.0-SNAPSHOT</neo4j-ogm.version>
现在我无法通过我的测试，但有以下异常：

我做错了什么以及如何解决这个问题？
答案 0 :(得分：1)
我已使用正确的依赖项解决了该问题：
<spring-data-neo4j.version>4.2.0.BUILD-SNAPSHOT</spring-data-neo4j.version>
<neo4j-ogm.version>2.1.0-SNAPSHOT</neo4j-ogm.version>
<强>已更新
