I got this while trying to build this morning:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:3.9.0:go-offline (default-cli) on project neo4j-genai-plugin: The following artifacts could not be resolved: com.neo4j:enterprise-it-test-support:jar:2026.05.0 (absent): Could not find artifact com.neo4j:enterprise-it-test-support:jar:2026.05.0 in central (https://repo.maven.apache.org/maven2) -> [Help 1]

This seems to be an upstream mistake; community/genai-plugin/src/test/java/org/neo4j/genai/ai/file/embed/FileVectorEmbeddingRBACTest.java:31-32 is an enterprise-only test. in community/genai-plugin/pom.xml it is pulling com.neo4j:enterprise-it-test-support into every default community build. The patch (name it fix-genai-plugin.patch):

In PKGBUILD:

1. Add "fix-genai-plugin.patch" as a last entry to the sources= array
2. Add "SKIP" as a last entry to the sha256sums= array
3. In the prepare() function, right under cd $_pkgname-$pkgver add:
4. patch -p1 < "$srcdir/fix-genai-plugin.patch"

After that, makepkg and you should have a fresh neo4j-community package.

I filed a bug upstream.

• $bin_archive seems to have changed from neo4j-community-$pkgver to neo4j-$pkgver/neo4j-community-$pkgver
• LICENSES.txt does not seem to exist anymore
• NOTICE.txt does not seem to exist anymore
• conf/* files are not found

I had to change $bin_archive to "$srcdir/neo4j-$pkgver/neo4j-community-$pkgver" (note: relative path didn't work, not sure why), and I had to remove the "$bin_archive/LICENSES.txt" and "$bin_archive/NOTICE.txt" from the install line (all in the package() function).

@rubin55 I will look into this change soon, thanks for your kind words

I just discovered this package is being kept up-to-date again, much happiness. Fwiw, I would like to suggest a few changes:

The above diff does the following things:

• I succesfully compiled and ran all unit- and integration tests with GraalVM Java 25; hence java version can be >=21 instead of =21;
• I suggest letting the user choose however they want to java, using archlinux-java set, and don't override JAVA_HOME and PATH;
• This package (correctly!) provides cypher-shell, hence should conflict with cypher-shell AUR package, also with neo4j-community-bin;
• I suggest having a provides line that explicitly provides neo4j, neo4j-community, and cypher-shell

Thanks for the great packaging job, I'm very happy to run a from-source Neo4j.

@r4um I will look into it, thanks for reporting

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.
