neo4j 2.0无法启动 [英] neo4j 2.0 having trouble starting

问题描述

我有我的DB_Path

I have my DB_Path

String DB_PATH = "path/to/data/graph.db"

然后我正在运行

GraphDatabaseService graphDb = new EmbeddedGraphDatabase(DB_PATH)

我遇到的（完全例外）

但是如果我之前运行clearDB ie

However if I run a clearDB before i.e.

try
{
   FileUtils.deleteRecursively(new File(DB_PATH));
}
catch ( IOException e )
{
   throw new RuntimeException( e );
} 

任何人都有更多的想法吗？谢谢！

Anyone have any more thought into this? Thanks!

推荐答案

原来这是版本问题。您需要在Java 7

Turns out it was a versioning problem. You need to run this in Java 7
