Could not use Neosemantics plugin

[Sayed Nafiz Haider]

I am facing problem while deploying the neosemantics plugin in Windows 10.

I am following the instructions to use the stored procedure which can take the OWL file and convert into a Neo4j ontology. I have built using maven and copied the neosemantics-[…].jar file to the plugin directory. The neo4j.conf file in my case was located in this “C:\Users\Nafiz\AppData\Roaming\Neo4j Community Edition” folder.  Added the line as you instructed at “https://github.com/jbarrasa/neosemantics”. However, after I try to close and kill the neo4j-ce.exe and run again, I receive errors: ” Starting Neo4j failed: Component ‘org.neo4j.server.database.LifecycleManagingDatabase@7e45466d’ was successfully initialized, but failed to start. Please see attached cause exception.”

I have tried the zip release of the same version and tried using console application, updated the conf file. Still I see the error. Any help is much appreciated.

Sounds like a version issue, pleaese check the apoc docs for the right version to deploy to 3.1.3

Same for neosemantics
