Neo4j嵌入式：java.lang.UnsupportedOperationException: 没有安装查询引擎。

neo4j
3

当我尝试执行针对嵌入式Neo4J实例的查询时，我遇到了以下异常：

No query engine installed.
java.lang.UnsupportedOperationException: No query engine installed.
    at org.neo4j.kernel.impl.query.NoQueryEngine.noQueryEngine(NoQueryEngine.java:56)
    at org.neo4j.kernel.impl.query.NoQueryEngine.executeQuery(NoQueryEngine.java:33)
    at org.neo4j.kernel.impl.factory.ClassicCoreSPI.executeQuery(ClassicCoreSPI.java:77)
    at org.neo4j.kernel.impl.factory.GraphDatabaseFacade.execute(GraphDatabaseFacade.java:429)
    at org.neo4j.kernel.impl.factory.GraphDatabaseFacade.execute(GraphDatabaseFacade.java:412)
    at org.neo4j.kernel.impl.factory.GraphDatabaseFacade.execute(GraphDatabaseFacade.java:396)

以下依赖项已包含："org.neo4j" % "neo4j-cypher" % "3.1.3"

这是我的代码片段，我从我的测试中执行：

val graphDb = new GraphDatabaseFactory().newEmbeddedDatabase(new File(my_db_path))
graphDb.execute(my_query)

这是Neo4J部分的依赖树:

有人知道这里出了什么问题吗？

提前感谢。

请分享你的 pom.xml。 - Bruno Peres
这实际上是一个SBT，但这些是URL： build.sbt - https://github.com/Supernova-Team/hubble/blob/features/hubble-graphite-writer/build.sbt 依赖项：https://github.com/Supernova-Team/hubble/blob/features/hubble-graphite-writer/project/Dependencies.scala并且它在以下项目中失败 - hubbleGraphiteReaderDependencies。 - Doe

运行时验证正确的类路径

为了加载Cypher引擎，您需要一些名为"neo4j-cypher-compiler*.jar"的JAR文件。在调试模式下评估System.getProperty("java.class.path")以查看JVM访问的完整JAR列表。根据您的SBT输出，看起来您已经有这些JAR文件，但是运行时才是唯一的真相。

原因＃1：依赖项遮蔽

可能是您的某个依赖项与neo4j的传递依赖项发生冲突。将neo4j放在SBT中更高的位置可以解决此问题。 （这就是我所做的）

原因＃2：达到最大命令行长度（仅限Windows）

Neo4j有大量的JAR文件。可能是java命令对于Windows的最大字符数太长了。请参见：如何在Windows中设置长Java类路径？
