Arch Linux User Repository

i don't know if this is obvious to everyone but i had to switch my system java default to openjdk 17 via 'sudo archlinux-java set java-17-openjdk'. compile failed with a default version of 21.

Getting this when running either neo4j start or neo4j-admin

ERROR! Neo4j cannot be started using java version 1.8.0_265. 
* Please use Oracle(R) Java(TM) 11, OpenJDK(TM) 11 to run Neo4j.
* Please see https://neo4j.com/docs/ for Neo4j installation instructions.

Have you thought about moving the jars to /usr/share/java/neo4j/lib?

I had more success getting neo4j-admin to work with the following patch:

Updated

Getting it to run:

$ sudo -s     #Not sure this is fully needed, but this outdated crap is annoying)
# mkdir -p /usr/share/java/neo4j/logs/
# NEO4J_HOME=/usr/share/java/neo4j neo4j start

It'll complain that /usr/share/java/neo4j/conf/neo4j.conf doesn't exists. And if you're here for bloodhound, then simply login to the web-tool once via http://localhost:7474/ and change the password before running bloodhound. If it still doesn't work, do

# cd /usr/share/java/neo4j/data/databases/
# mv graph.db/ graph.db.orig
# cp -r /usr/share/bloodhound/BloodHoundExampleDB.graphdb/ graph.db

And you'll get the example up and running, which you can wipe.

I am unhappy that this package is vastly outdated.

Symlink is broken:

$ cypher-shell
find: ‘/usr/bin/../share/cypher-shell’: No such file or directory

A quickfix is to add neo4j binary folder to $PATH:

export PATH="/usr/share/neo4j/bin/:$PATH"

So the actual cypher-shell script gets called first.

Thanks, oliv. Updated.

The systemd service file must be updated as neo4j java libraries are now stored in a different folder: From: Environment=NEO4J_HOME=/usr/share/neo4j

To: Environment=NEO4J_HOME=/usr/share/java/neo4j

I've made a new package which uses the latest git version here: https://aur.archlinux.org/packages/neo4j-git/

It's based on the structure of the Debian package.

I have multiple issues with this package.

The default enviroment variables is set wrong for me, I need to change at least NEO4J_HOME and when I try execute the server I receive:

Error: Could not find or load main class org.neo4j.server.CommunityEntryPoint
