Using openjdk 21

For anyone that needs neo4j-browser plugin I created a hook with a script to updated it and install it when the package neo4j-community updates.

The hook located at /etc/pacman.d/hooks/neo4j-browser.hook

[Trigger]
Operation = Install
Operation = Upgrade
Type = Package
Target = neo4j-community

[Action]
Description = Update Neo4j Browser JAR for neo4j-community
When = PostTransaction
Exec = /usr/local/bin/update-neo4j-browser

The script located at /usr/local/bin/update-neo4j-browser

#!/bin/sh

set -e # Exit immediately on error

# Get the Neo4j version, trimming unnecessary spaces or newlines
NEO4J_VERSION=$(neo4j --version 2>/dev/null) || {
    echo "[!] Failed to determine Neo4j version. Ensure Neo4j is installed and accessible."
    exit 1
}

# Construct the download URL
DOWNLOAD_URL="https://repo.maven.apache.org/maven2/org/neo4j/client/neo4j-browser/${NEO4J_VERSION}/neo4j-browser-${NEO4J_VERSION}.jar"

# Set the plugins directory and destination file
PLUGIN_DIR="/var/lib/neo4j/plugins"
DEST_FILE="${PLUGIN_DIR}/neo4j-browser-${NEO4J_VERSION}.jar"

# Create the plugins directory if it doesn't exist
if [ ! -d "$PLUGIN_DIR" ]; then
    echo "[*] Creating plugins directory at $PLUGIN_DIR"
    mkdir -p "$PLUGIN_DIR"
    chown -R neo4j:neo4j "$PLUGIN_DIR"
    chmod -R 755 "$PLUGIN_DIR"
fi

# Download the Neo4j Browser JAR file
echo "[*] Downloading Neo4j Browser version ${NEO4J_VERSION} from ${DOWNLOAD_URL}..."
if ! curl -fsSL -o "$DEST_FILE" "$DOWNLOAD_URL"; then
    echo "Failed to download Neo4j Browser JAR from ${DOWNLOAD_URL}."
    exit 1
fi

# Set the correct permissions for the JAR file
echo "[*] Setting permissions for $DEST_FILE..."
chown neo4j:neo4j "$DEST_FILE"
chmod 755 "$DEST_FILE"

echo "[*] Neo4j Browser ${NEO4J_VERSION} installed successfully."

Remember that the script needs sudo if you run it manually else the download will fail. This is not an issue when triggered by Pacman/yay.

After starting/restarting the service sudo systemctl restart neo4j.service navigate to http://localhost:7474

for anyone who needs to download neo4j-browser you can get it from the maven repo:

https://repo.maven.apache.org/maven2/org/neo4j/client/neo4j-browser/5.24.0/

Please add neo4j-browser to this package. It doesn't make sense to install it manually.

Can we get neo4j-browser added to this? It seems that with the newer versions the browser is in a separate repo. No idea how hard that would be.

@hainkind I needed to do the same. Took me a second but I definitely think its worth mentioning for others.

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.

@carsme - No problem. Thank you for updating it so quickly.

@tjcim My bad, should be fixed in 5.17.0-2. Thanks for reporting!
