Ich habe versucht, von Neo4j 2.3 auf 3.0.1 zu aktualisieren. Ich kann die Datenbank als Dienst starten, kein Problem.

Aber wenn ich versuche, eine ausführbare Neo4j-Datei zu erstellen und auszuführen, finde ich einen Fehler, den ich nicht beheben kann. Unter Neo4j 2.x kann ich problemlos ausführbare Dateien erstellen. Unten ist meine Hauptmethode:

public class StartDB {
    public static void main(String[] args) {
        new GraphDatabaseFactory()
        .newEmbeddedDatabaseBuilder(Paths.get(args[0]).toFile())
        .loadPropertiesFromFile(args[1])
        .newGraphDatabase();
    }
}

Ich habe einen einfachen POM mit 1 Abhängigkeit:<dependencies> <dependency> <groupId>org.neo4j</groupId> <artifactId>neo4j</artifactId> <version>3.0.1</version> </dependency> </dependencies>

Die Befehlszeilenargumente sind die Pfade zu meiner Datenbank bzw. zu meiner Konfiguration. Nachfolgend finden Sie die Stapelverfolgung dieses Diagramminstanziierungsfehlers.

Da ich die DB als Dienst mit "bin / neo4j" starten kann, dachte ich, dass es eine Diskrepanz zwischen den Dateien unter /neo4j-community/3.0.1/lib und den von Maven bereitgestellten Dateien geben muss. Ich habe versucht, meine ausführbare Datei mit Java -cp "/neo4j-community/3.0.1/lib/*" ohne Erfolg auszuführen. Jede Hilfe wäre dankbar.
