Neo4j Browser configuration for Spring Boot with embedded Neo4j

Add these dependencies to pom.xml:

    <dependency>
        <groupId>org.neo4j.app</groupId>
        <artifactId>neo4j-server</artifactId>
        <version>2.3.6</version>
    </dependency>
    <dependency>
        <groupId>org.neo4j.app</groupId>
        <artifactId>neo4j-server</artifactId>
        <version>2.3.6</version>
        <classifier>static-web</classifier>
    </dependency>

Invoke this method,

    @SuppressWarnings("deprecation")
    public void neo4jBrowser() {
        EmbeddedDriver embeddedDriver = (EmbeddedDriver) Components.driver();
        GraphDatabaseService gdb = embeddedDriver.getGraphDatabaseService();
        try {
            WrappingNeoServerBootstrapper neoServerBootstrapper;
            GraphDatabaseAPI api = (GraphDatabaseAPI) gdb;

            ServerConfigurator config = new ServerConfigurator(api);
            config.configuration()
                .addProperty(Configurator.WEBSERVER_ADDRESS_PROPERTY_KEY, "127.0.0.1");
            config.configuration()
                .addProperty(Configurator.WEBSERVER_PORT_PROPERTY_KEY, "8686");

            neoServerBootstrapper = new WrappingNeoServerBootstrapper(api, config);
            neoServerBootstrapper.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

I do this from 

    @EventListener
    public void onApplicationEvent(ContextRefreshedEvent event) {
        neo4j.neo4jBrowser();

To ftp a Maven artifact to Sharefile use Wagon and the Wagon plugin: pom.xml

  <distributionManagement>
    <repository>
      <id>ftp-repository</id>
      <url>ftp://newrelic.sharefileftp.com</url>
    </repository>
  </distributionManagement>

  <build>
    <extensions>
      <extension>
        <groupId>org.apache.maven.wagon</groupId>
        <artifactId>wagon-ftp</artifactId>
