java - Gremlin 控制台无法初始化 neo4j2 嵌入式数据库

Question

我想使用 Gremlin 控制台对嵌入式 Neo4j2 数据库进行一些 Gremlin 查询。通过 Rexster 的 Gremlin 不是问题。

当我尝试加载图表时，收到以下错误消息:

org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.kernel.impl.transaction.XaDataSourceManager@4405a711' was successfully initialized, but failed to start. Please see attached cause exception 

具有以下堆栈跟踪:

有人可以帮助我让 Gremlin 控制台与 neo4j2 图形数据库一起使用吗？

提前致谢

正如 cybersam 已经提到的，堆栈跟踪的相关部分是:

org.neo4j.kernel.impl.storemigration.UpgradeNotAllowedByConfigurationException: Failed to start Neo4j with an older data store version. To enable automatic upgrade, please set configuration parameter "allow_store_upgrade=true"

如果您认为您的数据存储区与您正在使用的库版本相同，请仔细检查类路径是否有重复项。如果您有两个不同的版本，通常无法确定使用哪一个。
