Apoc failed to find a compatible version

Question

I'm brand new, fresh and clean with Neo4J. Just downladed and installed the Neo4J Desktop application, working offline. Noticed that the plugins don't get the install button enabled.

Creating a graph DB and trying to install manually the apoc plugin with latest jar file (compatible one), it fails to get loaded apparently.

Using NEO4J Desktop 1.1.17 offline + server 3.5.2 + APOC 3.5.0.2 jar in plugins folder

I've followed the online doc and updated neo4j conf auhtorizing things in there.

dbms.security.procedures.unrestricted=apoc.*
dbms.security.procedures.whitelist=apoc.*

Restarted things but still with no success. What Am I doing wrong in here ? Seems quite a basic issue but as there is no stupid question...

Thanks for your feedbacks Best regards Any hint.

Answer 1

I have neo4j server (not desktop) version 3.5.4.

I downloaded apoc 3.5.0.3 which if memory serves was a zip archive. After unzipping, I copied the one jar into my plugins directory.

I modified the config file as you indicated. I used commas to separate the entries.

I did not update the whitelist parameter which remains commented out in my config file.

Next I restarted neo4j and the apoc procedures seem to work.

Have a look at my transcript below for the details of my setup:

FWIW, the graph algorithms procedures also work.

It is possible that you have two installations and modified the non-running one???
