How to debug gds with neo4j CE

[fantaga]

Dev Env:

GDS version: 2.12.1
Neo4j version: 5.26.0-SNAPSHOT
Operating system: Windows 11
IDE: IDEA 2022
JDK:OpenJDK 17.11

Desrription:

1. I try to debug graph-data-science-2.12.1.jar on neo4j5 in embeded way.
2. I put the jar file into ${NEO4J_HOME}/plugins and modified ${NEO4J_HOME}/conf/neo4j.conf .dbms.security.procedures.unrestricted=gds.* dbms.security.procedures.allowlist=gds.*
   added.
3. then I run debug with org.neo4j.server.CommunityEntryPoint#main() method, App parametrers are follow:
   --home-dir=D:\Dev\Java\Bigdata\neo4j-community-5.16.0-SNAPSHOT --console-mode=true

Result

Console output prints like follows:

It seems that something goes wrong with procedure.GraphDataScienceProcedures facade did not be registried at org.neo4j.procedure.impl.FieldInjections#components.

sincerly!

Hey,

you need to use a compatible GDS version, depending on your Neo4j version. A list of compatible versions can be found in our documentation at https://neo4j.com/docs/graph-data-science/current/installation/supported-neo4j-versions/

Your message says that you use 5.26, your log says that you use 5.16; GDS 2.12 is not compatible with either of them. Also, we can only claim compatibility for released versions of Neo4j, if your SNAPSHOT version is representing some in-development state, there is a chance that GDS is just not be compatible with that state.

Thx for ur solutions.
I tried the realease edtion neo4j-community-5.26.0 and gds neo4j-graph-data-science-2.13.1.jar,it did not work.

Is it possible that I run Neo4J main method in source code？ it's ok with starting with win-shell neo4j.bat start.

thx anyway!
